Then embryos were isolated from the endosperm and pericarp by gently pressing the seed at the cotyledon end.
Rather, a stimulus released from the cotyledon is more likely to induce the major cell wall degrading enzyme, endo- mannanase, within the endosperm itself.
Diaspores are gravity dispersed and the seed coat rapidly decays, exposing cotyledons to the immediate environment prior to germination.
The seeds are flattened and seedlings are phaneroepigeal with leafy cotyledons.
Prior to acquisition of desiccation tolerance, seeds produced seedlings with either shortened radicle tips, unexpanded hypocotyls or folded cotyledons.
To facilitate equilibration, seed cotyledons were chopped into c. 1 mm3 pieces.
In cotyledons, methyl esterification ranged from 25 to 40 mole% and was 31 mole% after desiccation.
Seedlings with emerged cotyledons were monitored and removed each time from the pots.
