Other claims from this paper (6)
- Observation Embryos from 93 and 70% viability stocks did not differ significantly.
- Observation Reserve mobilization was reduced in 70%-viable seeds.
- Observation Alpha-amylase production decreased.
- Mechanism The authors suggest non-embryonic alterations contribute to seed viability loss.
- Mechanism Failing nutrient supply may mediate this effect.
- Mechanism An inhibitor or toxic substance may also contribute.
