In some trees, like jackfruit, some citrus, and avocado, the seeds can be found already germinated while the fruit goes overripe; strictly speaking this condition cannot be described as vivipary [citation needed], but the moist and humid conditions provided by the fruit mimic a wet soil that encourages germination. However, the seeds also can ...
In home gardens, for example, the seeds of plants which are otherwise difficult to grow from seed may be made viable through scarification. The thawing and freezing of water, fire and smoke and chemical reactions in nature are what allow seeds to germinate but the process can be sped up by using the various methods described thus far.
The bean-shaped achenes of the jackfruit are coated with a firm yellowish aril (seed coat, flesh), which has an intense sweet taste at maturity of the fruit. The pulp is enveloped by many narrow strands of fiber (undeveloped perianth ), which run between the hard shell and the core of the fruit and are firmly attached to it.
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
There have been several seeds known at different times as the oldest viable seed. Dormancy allows seeds to survive for extended periods, which can aid in seed dispersal and spread out the growth and establishment of seedlings , increasing the likelihood that some of the next generations survive if conditions are not suitable for seedling ...
Niger seed yields about 30–35% of its weight in oil which is clear, slow-drying, and edible. Niger seed oil is a polyunsaturated semi-drying oil. It has a pale yellow or orange color with a nutty taste and sweet odor. The raw oil has a low acidity and can be used directly for cooking.
Methyl jasmonate (abbreviated MeJA) is a volatile organic compound used in plant defense and many diverse developmental pathways such as seed germination, root growth, flowering, fruit ripening, and senescence. [1]
Seed oils are characterized by the industrial process used to extract the oil from the seed and a high content of polyunsaturated fatty acids (PUFAs). [10] Critics' "hateful eight" oils consist of canola, corn, cottonseed, soy, sunflower, safflower, grapeseed, and rice bran oils, [ 8 ] which are creations of industrialization in the early ...
