It was a physical feature that delayed germination until the cell walls broke and permitted the influx of water necessary for germination.
Thus, in the absence of dormancy, delayed and slower rates of germination are evidence of reduced seed vigour and quality.
The cytokinin or ethylene requirements for overcoming thermoinhibition of lettuce germination can also be eliminated or diminished by removing or weakening the endosperm.
Perhaps an orderly sequence of metabolic events is necessary to 'set the stage' for germination.
Factors limiting tropical rain forest regeneration in abandoned pasture: seed rain, seed germination, microclimate, and soil.

Germination and seedling growth of selected dry tropical forest species.
However, they are not particularly apparent at 1 day of germination after priming and their role in the germination process per se is uncertain.
