The leaves are oblong–ovate to cylindrical with have short petioles, measuring from 14 to even 16 cm in length with the width measuring 5–7 cm. Textures can go from firm to pudding like to almost wet. Some knowledge of the biology of seeds is essential to their proper handling. We believe, if your climate allows, growing outdoors even at germination stage is far better than doing the same indoors. Some species have incredibly strong odor, many people being literally revolted by it, while other types are all but odorless. )The Effect of Seed Position on Germination and Seedling Growth of Durian (Durio zibethinus Murr. In durian germination, the cotyledons are lifted above the soil by elongation of the hypocotyl, but they remain inside the seed. de Vogel (1980) described 16 different types of seedlings among the 150 woody taxa he studied in Malaysia, compared to the four described by Ng (1978). In order to retain the characteristic organoleptic qualities, in some countries, overripened fruits are fermented with salt or sugar to produce ‘tempoyak’ (acid-fermented durian) or ‘lempok.’ Dodol, a traditional sweet dish, is also prepared by cooking durian pulp with sugar. Mannose, citramalic, gluconic, and keto-l-gulonic acids were shown to be strongly correlated to final postharvest stages. The fruit is oblong to round-shaped, with the outer skin being light-green to brown in color (weighs between 1 and 3 kg, 15–16 cm in diameter, and 30–32 cm long). 18 16 5. When the fruit splits and a couple days have passed, and the fruit meat is starting to turn color (darker), it is a good time to harvest. This has the advantage of being able to sow a bunch of seeds from the same collection/tree and not have to setup all the pots until you know they have germinated. Durian fruit is split open to reveal the edible fruit and seeds. 22 8 9. Lai was characterized by a less intense sulfury, fruity, and sweet aroma since it contained fewer sulfur and ester compounds than durian. Indoor air quality is usually very poor due to things like a lot of organic things growing small fungi and releasing spores. In durian germination, the cotyledons are lifted above the soil by elongation of the hypocotyl, but they remain inside the seed. Many materials are great at one or the other but fail at doing both adequately. Most ethylene production from the fruit is related to the husk, which is derived from the ovary wall, whereas the pulp produces only small amounts (Siriphanich, 1996). The durian inflorescence will be in full bloom during 16.00-16.45 hrs, and the anthers burst and shed the pollen grains during 17.45-19.00 hrs. Once the seed start germinating, they can be placed onto soil as above. b. Germinate the seeds in seed box or seed bed with coco peat, fine river sand or saw dust as germination medium. They can grow to over 8kg in weight, be about the size of a basketball, and are covered in variable spikes. We have used multiple methods for germinating durian seeds and time and time again we just keep going back to the basics of what it wants. such as Durian germination pattern occurred for non-emerged seed coats. In her comprehensive survey of the seedlings of Barro Colorado Island (Panama) and the Neotropics, Garwood (2009) recognized seven groups of dicot and three of monocot seedlings and developed keys based on morphological characters to allow one to identify the family to which a seedling belonged. SPME, simultaneous distillation–extraction, and LLE, combined with GC-FID, GC-MS, aroma extract dilution analysis, and odor activity value were used to analyze volatile compounds from banana fruit cv. Waxing or surface coating of durian has been reported to increase the resistance of the peel to gas exchange, thus creating modified atmosphere internally to extend fruit life (Tongdee et al., 1990a). 13 4 1. This product is made from fully ripe durian aril, mixed with sugar and coconut milk or with sugar alone, stirred over a low heat until thickened. Tao Feng, ... Lingyun Yao, in Evaluation Technologies for Food Quality, 2019. 9 15 1. Many things can cause dehydration, and it isn’t always lack of water in the soil. G.A. In the other limit of liquid fraction, wet foams are simulated with variants of Durian’s bubble model (Durian, 1995), or soft-disk models (Langlois et al., 2008; Rognon and Gay, 2009), more familiar in the field of granular materials. 19 18 0. Toivonen, in Postharvest Biology and Technology of Tropical and Subtropical Fruits: Fundamental Issues, 2011. The moss should be placed very loosely to allow good air flow, but to cover the seeds and protect from light and exposure to dehydration. Interest in the reproductive phase of the life cycle of tropical species has led to publication of several volumes of drawings of tree seedlings (e.g., Duke, 1969; de Vogel, 1980). GC-MS has been used to characterize tomato pericarp composition in transgenic plants, to assess metabolic diversity of tomato species, to measure metabolic changes associated with tomato fruit development, and to characterize biochemical changes during the development, ripening, and postharvest shelf life of tomato fruit. Germinate Seeds Plants. A notable recent addition to the literature is the work of Cantat (2010), which augments a dry 2D foam simulation using the vertex model (in which films are assumed straight) with a surface tension that varies with film stretching rate. The tree is small, slender, and evergreen when domesticated as a garden plant in lowland South America. Plate XII. We prefer sunlight under 60-70% shade cloth, but under T5/T8 fluorescent fixtures about 15cm away will also suffice. And good fresh air exchange. Carol C. Baskin, Jerry M. Baskin, in Seeds (Second Edition), 2014. RESULTS The result of the study of early seedling Distribution and Ecology Occurs in CYP and NEQ, widespread. Types of germination reported by Ng (1978) in Malayan rainforest trees. The product can be stored for a long time in a sealed metal container. High temperatures and humidity levels need to be maintained, but not everyone thinks about the alterations they are making. A step be step guide to Growing Rambutan tree indoors. Plate IX. Lastly outside has UV light from the sun, which cannot be matched with the best indoor lighting, and also has far great natural beneficial organisms. The best approach, however, is also one of the most obvious: start by choosing whole products that have inherently high quality in terms of maturity, colour, SSC or SSC:TA ratio, texture, taste, and aroma. (Chapter 5) (a) a cross section of a ripe Monthong durian fruit showing air space between the aril and the husk (notice that most seeds are aborted); (b) checking durian maturity by determining dry matter of the aril using a microwave oven; (c), a chilling injury symptom on durian husk; (d) Phytophthora rot on a durian fruit; (e) a durian dehusking tool; (f) durian paste on display shelf. Durian fruits are high in nutrition and bioactive compounds. Even though farm varieties are popular, some of the wild cultivars (e.g., D. kesudinarum and D. grandiflorus) are also known to produce edible fruits, but these are less preferred owing to poor quality and taste. Hardy in U.S. Department of Agriculture plant hardiness zones 10 through 12, the evergreen tree is grown … Browning of seed and not germinating is usually caused from drying out. Plum Blossom Spring. The soursop tree is around 8–10 m in height, upright, with low branches when fully mature. Furthermore, the pulp is developed from the overlap of several layers of aril, which could result in different physiological inductions between each overlapped layer, responsible for unharmonized ripening of aril pulp which is similar to different maturities between the segments of mangosteen and longkong fruits. Frankies in Hawaii has a few durian varieties. Therefore, it is imperative to reduce weight loss of durian fruit after harvest. Durian are slow to start! This also requires more attention by the grower to make sure things do not dry out. Unlike some other tropical plant species, the durian seedling will form right inside the seed, and the seed itself remains a big bulk shape surrounding it, making it very easy for them to stick or for the seed itself to break the fragile young stem. Gibberellins promotes seed germination and secretes enzyme to break stored food in seed. (Chapter 6) Chilling injury in feijoa. Fatty acids contain the methyl esters of myristic acid, linoleic acid, oleic acid, 10-octadecenoic acid, palmitoleic acid, palmitic acid, and stearic acid. Seeds Planting Plants. Delay Senescene; Induce parthenocarpy in pome fruits; Break bud and seed dormancy - wherein. Take a tray/pot that is at least 10cm deep. Plate XI. Today, attempts are being made to prepare bakery products with durian flavor using the fruit powder. For example, durian, a kind of tropic fruit, has a unique sweet taste and strong stinky aroma. In the case of Durio, seeds can be stored successfully anywhere from 3-20 days (many say 1 week). In its most basic incarnation, the bubble model incorporates a repulsive force between (spherical) bubbles and a friction force proportional to their relative motion. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Leaf Fresh Green. Regardless of cultivars, a substantially higher concentration of total volatile compounds was observed in pericarp than in locular gel, associated with higher levels of aldehydes, hydrocarbons, and nitrogen compounds. Shuaibu Babaji Sanusi, Mohd Fadzelly Abu Bakar, in Exotic Fruits, 2018. Therefore, the self-fertilization inside the flower Mold should not be allowed to spread far, fungal pathogens are a big problem for some people germinating durian seeds. Many of these fruits, including mango, pineapple, mangosteen, durian, jackfruit, litchi and others, are somewhat intimidating to attempt to eat for people who are unfamiliar with them. I was going to put it in a soiless mix in a pot and put that on a heat mat. [62] detected 46 odor-active compounds from Thai durian “Monthong” using aroma extract dilution analysis and GC-olfactometry. W.C. Schotsmans, ... A.B. The seed won't come off the seedling often because they are just slow. So what we want is a fairly airy medium that can hold moisture in its body to maintain a high humidity in all of the air pockets it provides. The special aroma of durian makes this fruit favored only by limited consumers. The durian fruit gets its popularity based on the distinctive odor, aroma, and taste. Plant them lengthwise with the "eye" pointing more towards the soil. The fruit skin is covered with 1–2 cm long thick hexagonal spines and is very hard (55–66%). Owing to a short shelf life, efforts are being made to commercialize durian flesh to convert into fruit powder. Another is the Lattice-Boltzmann method (Benzi et al., 2009), which may offer the ability to investigate the coupling between the flow in the films and in the Plateau border network. Another trend in the FC fruit industry is a movement away from extended shelf life claims or requirements of two weeks or more that are based on product appearance, toward more realistic shelf life periods based on retention of good texture, taste and aroma qualities. Take some clean sphagnum moss and soak it in water until it is fully hydrated. (Chapter 6) Chilling injury in feijoa. Assuming it is still viable, how do you grow it from seed. Figure 9.3. SEED ANATOMY AND GERMINATION OF DWARF PALM Revista Brasileira de Sementes, vol. Thirty-one odorants were considered as odor-active compounds and contributed to the typical banana aroma; 11 of them were reported for the first time as odor-active compounds [66]. As reported in this chapter, a number of approaches and technologies are available or are being researched that have the potential to help realize this goal for FC subtropical and tropical fruits. Use fully developed seeds from mature/ripe durian fruits of the recommended varieties. 3.7. If growing indoors and air quality is going to be poor, it will be tricky to maintain the right temperature and humidity without sacrificing fresh air exchange. 8. This unfortunately likely means the fruit will be spoiled, most likely by bugs, and will not be great to eat. [68] investigated the differences in volatile profile between pericarp tissue and locular gel in tomato fruit. If you need to make a short trip break away and concurrently at the same time enjoy the taste of durians, then you should be part as our prestige guest in durian tour. Creation of innovative, new combinations of different FC fruit mixes is one approach that may be taken. By continuing you agree to the use of cookies. They originate from SE Asia and have for many years being considered the "King of Fruits". For example, durian, a kind of tropic fruit, has a unique sweet taste and strong stinky aroma. Despite its higher fiber content, the durian seed kernel is less gritty in comparison to whole meal wheat flour. It is so important no to sacrifice air quality for humidity, always find a way to increase humidity, do not decrease air flow. Of course the durian was frozen so don't know if it will be vaible. The seeds should be washed with clean water when they are harvested from the fruit. Place the seeds as you would above on the soil, but onto the moss. Cross-section of Annona muricata fruit. Although the seeds should not be exposed to light, at least until the tap root shows, it is important to provide it. Hasten seed germination; Ensure rapid and uniform seedling establishment; Shorten the time of exposure of potted seeds to pests and other stresses. Only plant your durian outside if you receive somewhere between 60–150 in (150–380 cm) of rain per year, and if the temperature stays above 45 °F (7 °C). Loosen up the moss and sprinkle it on top of the seeds filling to the top of the pot. So let’s briefly go over the requirements of Durio species seed germination. A. muricata L. is called soursop in English. (2006) reported a delay of dehiscence in durian fruit after waxing, which prevented water loss. (a) Internal symptoms include vascular browning and pink discoloration of the flesh; (b) external symptoms include longitudinal browning of the skin.Plate XII. Promotes seed germination; Promotes flowing in long day plants and inhibit it in short day plants. This may hold true for many tropical species as well. Toivonen, in, Postharvest Biology and Technology of Tropical and Subtropical Fruits: Fundamental Issues, Methods for modelling food cellular structures and the relationship between microstructure and mechanical and rheological properties, Shuaibu Babaji Sanusi, Mohd Fadzelly Abu Bakar, in, Pinto et al., 2005; Badrie and Schauss, 2010, Pinto et al., 2005; Coria-Téllez et al., 2016, The Molecular Nutrition of Amino Acids and Proteins. Ginkgo Germination Leaf. (Chapter 6) Ripening index for feijoa fruit (a) seed pulp half white, half clear; (b) all of seed pulp area clear, (c) all of seed pulp area clear, but darkening (greyish); (d) seed pulp is completely brown, (e) seed pulp and flesh are brown. Durian seed just starting to germinate. This may involve selection of cultivars with inherently high quality potential or firm texture as well as those with slow ripening behaviour that minimizes sensory changes during FC shelf life. 18 17 1. Tomato Shoots. Durio is a truly variably fruit genus, but luckily seeds, although finicky, germinate in much the same manner. High endogenous ethylene levels in durian husk induces the biological process of husk dehiscence during fruit ripening. Waxing reduces ripening processes, weight loss and dehiscence. (a) Internal symptoms include vascular browning and pink discoloration of the flesh; (b) external symptoms include longitudinal browning of the skin. Jackfruit Seed Propagation: Tips For Growing Jackfruit From Seeds Figure 2. of the seed evolution, Biology of seed development and germination physiology of seed. In epigeal germination, the cotyledons are carried above the soil surface by the elongating hypocotyl, and they expand and become photosynthetic in most species. This trend will most likely utilize new advances in edible film and active packaging development. Modified atmosphere packaging has been a standard component of FC handling throughout the history of the industry. Although they are from the tropics they don’t like standing in constant moisture, even the seeds. Should he send it in damp paper towel or dry? It is not super critical as the tap root will grow down with gravity. An expected trend is a re-examination of MAP design in conjunction with the development of FC fruit products made from more mature or riper fruit and the desire to maintain more of a fresh-picked flavour. Conversely, ready-to-eat durian pulp usually encounters the problem of failure to properly ripen or uneven ripening, due mainly to the very low levels of ethylene produced by the aril. Clean the seeds and rinse it of sugars. Durian paste is the most widely made processed durian across South-East Asia. Novel bakery products such as jam, candy, ice cream, juice, and fruit shake are also being attempted. I got this durian seed from a durian I ate. Most Durio fruit will split open when fully ripening, and this is the ideal time to harvest the seeds. Amazon.com : SD0549 Durian Seeds, Malaysian "King of Fruits" … It is our opinion that harvest time is the most critical aspect of Durio seed success. The volatiles profiles of durians have been investigated. The fruit is what gains real attention. I would even say wait until the very first signs fo mold, as that will allow maximum in fruit ripening before fungus takes its toll. Treatment may be done in several ways: 7.1 Tap water treatment. Gresorth 27 cm Fake Lifelike Durian Artificial Fruit Home Party Shop Christmas Decoration £27.69. Fresh-cut products that provide a convenient, ready-to-eat introduction to these fruits for the uninitiated consumer can serve to expand the consumption and economic demand for these fruits to new market segments. For retail packages it is often packed in clear plastic tubes (Plate IX F). Moisture & Water: One of the most common mistakes people seem to have with germinating durian seeds is that they keep them too wet. We supply enthusiasts and collectors as well as botanical gardens, nurseries and seed dealers of all sizes. It is important not to bury the seeds, as the see will not often come out of the soil when germinating and sometimes this leads to the tip of the plant rotting. This is probably most important to avoid rot, but the seedling will soon need it anyway. When durian pulp is removed from the fruit, it exhibits low respiration and ethylene production rates compared to the husk (Brooncherm and Siriphanich, 1991) which contains high activities of ethylene biosynthetic enzymes. The use of the durian fruit as a therapeutic agent to reduce cholesterol, in treatment of cardiovascular diseases, and as an antioxidant to prevent oxidative stress, obesity, and diabetic mellitus is also reported. The analyses led to the identification of 146 compounds, and 124 of them were positively identified. Li et al. The lipid content of durian seed kernels is low and comparable to that of avocado’s. According to their results, lai cultivars have less diverse sulfurs and esters as compared to durian, which were most probably the key reason for the different aroma characteristics of lai and durian. I have grown many plants from seed in my native land enduring the cold northerly winds of Northeast England. The seedling is wrinkled due to dehydration. Squeeze it in your hand as hard as you can to get most of the water out, this will make it slightly moist but not wet. I have a friend in Malaysia who is planning to send me some durian seed this week. The durian plant is a native of the Malay Peninsula but is widely cultivated in Thailand, the Philippines, and Indonesia, too. In Ng’s (1978) study, 64, 18, 10 and 8% of the 180 species had epigeal, hypogeal, semihypogeal and durian germination, respectively. One trend in the FC fruit industry is that plant breeders and FC companies are developing and selecting cultivars that are inherently suitable for FC processing.

Take your durian seeds and place them on top of the soil without burying them, just sitting them on top so they won’t tip over. When the soil starts drying out, water it a little, not so it drains through as you would a real plant, but just to wet the material in order for it to hold a high humidity and avoid dehydration of the seed. The giant fruits of the jackfruit (Artocarpus heterophyllus) hang from the branches of the 30- to 70-foot-tall tropical tree. 10 7 3. Plate IX. Aroma, a complex mixture of volatile compounds, plays a critical role in the perception and acceptability of fruits and vegetables. Wang et al. The edible part or aril is 22–30% encompassing big seeds (12–15%). Rambutan trees bear fruit that is indeed hairy in appearance. Durio species, collectively referred to as Durians, are a very unique and special tropical fruit. Potseed Germination Seeds: 4 Seeds Durian King of Fruit Rare Seed New viable Seed M51 £17.00. It has a white and juicy flesh, and the fruit may contain 127–170 seeds, depending on the size, distributed in the pulp. Because the seeds are in dormant state and need to absorb enough water to The tree produces an oval or conical shaped fruit, which it is a dark green in color when unripe and transform to lighter green when fully ripe. Gonzalez-Aguilar, ... P.M.A. The authors conducted further research, which disclosed that durian pulp overall odor can be mimicked by only two compounds: ethyl (2S)-2-methylbutanoate and 1-(ethylsulfanyl) ethanethiol [63]. We have found over the years that allowing the fruit to split and waiting an additional 2-3 days is far better as the seeds of many durian species will start germinating inside the fruit. Their flowers are 3.2–3.8 cm in length, which open in the early hours. (a)–(b) mature fruit – for fresh consumption; (c) fruit for processing; (d)–(e) late senescence (developed by The New Zealand Institute for Plant & Food Research limited, Mt Albert, New Zealand). 15 11 1. eeds from the durian fruit can be planted outside immediately after taking them out of the fruit, with no germination period necessary. Mold is a very common problem with such tropical fruit seeds, and is not overly bad in the case of Durio. ACC (1-aminocyclopropane-1-carboxylate) synthase (ACS) and ACC oxidase (ACO) activities in both the husk and pulp increase as the fruit ripens with ACS activity in the husk being higher than that in the pulp (Chaiprasart and Siriphanich, 2000). During on-vine ripening, an increase was observed for the major hexoses, glucose and fructose, cell wall components such as galacturonic acid, and for amino acids such as aspartic acid, glutamic acid, and methionine. Durian seeds germinating on sphagnum moss. We use cookies to help provide and enhance our service and tailor content and ads. Not sure if Bryan from Montoso has any. The seed casings were quite hard and I doubted whether they would rot sufficiently to allow further germination. Pericarp tissue possessed higher levels of cis-3-hexenal, hexanal, heptanal, octanal, nonanal, cymene, terpinolene, undecane, dodecane, 2-phenylethanol, 6-methyl-5-hepten-2-one, 2-methylbutyl acetate, 1-nitro-pentane, and 1-nitro-2-phenylethane, while the abundances of 2-methylpropanal, butanal, 2-methylbutanal, 2-methyl-2-butenal, 2-methylpropanol, 3-methylbutanol, 2-methylbutanol, and 2-butanone were higher in locular gel. They can grow to over 8kg in weight, be about the size of a basketball, and are covered in variable spikes. It may be consumed directly as dessert or used as a stuffing in Chinese moon cake (Maneepun et al., 1994; Paweenakarn et al., 1992). It is really that easy, the only things that must be monitored and maintained are fresh air, humidity and temperature. Nearly 250 volatile constituents have been identified for several fresh and processed banana products; however, only some of them have been recognized as banana flavor contributors. Light: We have noticed that Durio seeds that are exposed to light start to discolor and become hard to germinate. Based on headspace solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC-MS) analysis, a total of 42 volatile compounds were detected in FL 47 and Tasti-Lee tomato fruits. Plant your seeds outdoors if you get lots of rainfall and high temperatures. Fill the container with the soil mentioned above, leaving 3-6cm at the top free. Total . You wan the area to feel "sticky" but when you rub the seeds your fingers should not become wet from condensed moisture forming on the seeds. We prefer and recommend using the sphagnum moss however and will continue the procedure using that as our medium below. Plate X. Locally also called rian tutong or durian maragang, ... 100,000 seeds are delivered worldwide. Woolf, in Postharvest Biology and Technology of Tropical and Subtropical Fruits: Cocona to Mango, 2011. (Chapter 7) Different stages of fig fruit development, externally and internally. The seed should sprout and … They originate from SE Asia and have for many years being considered the "King of Fruits". If the soil isn’t dry, it is likely a root problem, probably rot. In hypogeal germination, the hypocotyl does not elongate above the soil surface, and the cotyledons which remain inside the seed are at or slightly below the soil surface. This is common with a lot of ultra-tropical species and means that seeds cannot be stored long before they die. The middle ground – foams of intermediate liquid fraction and/or those with dissipative flow in the films – is less well described, mainly because of the difficulty in resolving the different length-s cales (films on one hand and the Plateau border network on the other). Dehydrating durian seeds are bad news and become increasingly harder to germinate the longer they are exposed to open air and light. We want to avoid damaging the "eye" of the seed, as this is where the hypocotyl (and eventually tap root) push out of the seed and we dont want to damage it. Temperature: Durian seeds need to be maintained at a fairly consistent temperature that is quite warm. (Chapter 5) (a) a cross section of a ripe Monthong durian fruit showing air space between the aril and the husk (notice that most seeds are aborted); (b) checking durian maturity by determining dry matter of the aril using a microwave oven; (c), a chilling injury symptom on durian husk; (d) Phytophthora rot on a durian fruit; (e) a durian dehusking tool; (f) durian paste on display shelf. Soil: We opt for a medium clay type soil (from outside) mixed with coco coir and medium washed sand in a 50:20:30 ratio. Lower temperatures have worked, but germination rates drop and times increase. Añabesa et al. The biggest issue with all Durio species is their seeds are recalcitrant. Another method we have used quite a lot, and sometimes come back to, is filling a tray about 4-5cm deep with moistened sphagnum moss. The idea is to provide maximum humidity, not high moisture. Gonzalez-Aguilar, ... P.M.A. 1 and 2. Keeping them at a constant 28-29C we have found to be ideal growing them in southern Taiwan. Indoors is also lacking in adequate air flow, generally having very stagnant air in relation to outdoors. We may also add some pumice at about 3-7mm grade. Among them, 24 were never reported to be found in durian before. It is important to identify the trace compounds contributing significantly to banana aroma. This is simply to wash away most of the sugars that will greatly increase the chances of fungi spores germinating and attacking the seed. The fruit of A. muricata is shown in Figs. De Vogel used developmental characteristics of juveniles as well as attributes of the cotyledons and hypocotyl in his classification system. Check the internet to find out your area's rainfall and average temperatures. They are very expensive. Typical banana-related aroma components such as hexanal, 2-pentanone, 2-pentanol, 3-methyl-1-butanol, 3-methylbutyl acetate (isoamyl acetate), and eugenol were detected, and differences in flavor profile were observed between ethylene and nonethylene-treated bananas at the same color stage and between bananas from different origins [65]. The quasi-static rheology of dry foams can be simulated with the Surface Evolver (Brakke, 1992; Wyn et al.. 2008), by assuming that the foam is always in equilibrium (a minimum of surface energy). Most people confuse this with wet or moist, they do not like being wet, but really like being humid! R. Bhat, G. Paliyath, in Encyclopedia of Food and Health, 2016. Durian fruits are seasonal and are popular as the ‘king of fruits.’ A matured tree bears fruit after 5–7 years of planting the seed, and fruits hung on a peduncle, which is firmly attached to the trunk and branch. Chalermchai Wongs-Aree, Sompoch Noichinda, in Postharvest Handling (Third Edition), 2014. Be transplanted to larger pots at a constant 28-29C we have noticed that Durio seeds that are underappreciated by segments.
