Other claims from this paper (4)
- Intervention effect Endosperm from six dormant lines produced no α-amylase unless GA3 was supplied.
- Mechanism The authors infer coadaptation between seed dormancy and dependence of endosperm hydrolysis on embryo-produced gibberellins.
- Mechanism Variation among nondormant lines argues against simple pleiotropy and suggests multiple loci or alleles.
- Association The authors infer that long-term endosperm stability gives little advantage to wild-oat seeds with brief soil residence.
