It is not exactly known how long dry plant specimens last in storage, but with proper conservation, they have been able to last many centuries. Specimens collected by Linnaeus in the eighteenth century and by Banks and Solander on the Endeavour voyage in 1788 are still excellently preserved. [4] The specimens may be whole plants or plant parts.

Drying starts at the bottom of the bin, which is the first place air contacts. The dry air is brought up by the fan through a layer of wet grain. Drying happens in a layer of 1 to 2 feet thick, which is called the drying zone. The drying zone moves from the bottom of the bin to the top, and when it reaches the highest layer, the grain is dry.
Step 1: Water imbibition, the uptake of water, results in rupture of seed coat. Step 2: The imbibition of the seed coat results in emergence of the radicle (1) and the plumule (2); the cotyledons are unfolded (3). Step 3: This marks the final step in the germination of the seed, where the cotyledons are expanded, which are the true leaves.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.
