How to use insights on the regulation of germination to improve crop seed and seedling quality in the broadest sense?

The way that nature regulates germination often conflicts with the requirements of the industry.

Nature Agriculture
One seed resulting in one plant is enough All seeds should germinate
Variation in time (bet-hedging) Uniform germination
Genetic variability preferred Genetically identical off-spring
Within their habitat Outside their habitat
Selection for fitness Selection for specific traits
Only short periods of dry seed Long periods of dry seed
Only propagation Propagation and Produce
Survive the environment Survive seed processing

Presenters are asked to address this issue in their presentations.
