Other claims from this paper (12)
- Observation Daylily flowers senesce and die within 24 hours after opening.
- Intervention effect Daylily flowers were insensitive to ethylene.
- Intervention effect Exogenous ABA prematurely caused loss of differential membrane permeability in daylily petals.
- Intervention effect Exogenous ABA prematurely increased lipid peroxidation in daylily petals.
- Intervention effect Exogenous ABA prematurely induced proteinase activity in daylily petals.
- Intervention effect Exogenous ABA prematurely induced RNase activity in daylily petals.
- Intervention effect ABA prematurely induced the same proteinase and RNase activity-gel patterns as natural senescence.
- Observation Endogenous ABA increased before daylily flowers opened.
- Observation Endogenous ABA continued increasing during daylily petal senescence.
- Intervention effect Sorbitol osmotic stress raised endogenous ABA levels.
- Intervention effect Sorbitol osmotic stress upregulated the same senescence parameters seen in natural and ABA-induced senescence.
- Observation The mRNA profile of sorbitol-treated prematurely senescing petals closely resembled natural senescence but resembled ABA-treated petals somewhat less.
