Seeds are stored in airtight aluminium bags. The number of seeds in each bag varies depending on the size of the seed, but on average each bag contains approximately 500 seeds. The facility has a storage capacity of 4.5 million seed samples. [62] The table below presents the cumulative total of samples (i.e. accessions) deposited by year.
Wheat seed. The endosperm is a tissue produced inside the seeds of most of the flowering plants following double fertilization. It is triploid (meaning three chromosome sets per nucleus) in most species, [1] which may be auxin -driven.

It may be membranous as in citrus where it is the only part consumed, or thick and hard as in the pyrenas of drupe fruits of the family Rosaceae such as peaches, cherries, plums, and ...
Seed dormancy. Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. [1] Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to ...
Apricot stones (kernels are inside) An apricot kernel is the apricot seed located within the fruit endocarp, which forms a hard shell around the seed called the pyrena (stone or pit). [1][2] The kernel contains amygdalin, a poisonous compound, in concentrations that vary between cultivars. Together with the related synthetic compound laetrile ...
Mustard seed. Mustard seeds against a scale of 20 millimetres (3⁄4 inch) Mustard seeds are the small round seeds of various mustard plants. The seeds are usually about 1 to 2 millimetres (⁄32 to ⁄32 in) in diameter and may be colored from yellowish white to black.
