Seed can last for many years; old spikes 9 to 12 years old have been found to have seed that remains 100% ...
Over time, seeds lose viability, which is the ability to initiate metabolic activity, cellular growth, and germination. Seeds have many cells and tissues that die over time, [ 1 ] and these deaths can be delayed or increased by environmental conditions the seed experiences.
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.
