Other claims from this paper (11)
- Observation PRD vines received 66% of the water supplied to controls on average.
- Intervention effect Initially PRD did not alter midday leaf and stem water potential.
- Intervention effect Initially PRD decreased stomatal conductance.
- Intervention effect Continued PRD lowered midday leaf and stem water potential relative to controls.
- Intervention effect Continued PRD decreased berry weight at harvest.
- Observation Beta-carotene and lutein declined after veraison under both irrigation treatments.
- Intervention effect PRD increased berry beta-carotene concentration near maturity at certain times.
- Association The PRD carotenoid effect was greater for lutein than beta-carotene.
- Association The PRD effect on hydrolytically released norisoprenoid concentration was greater in season two.
- Intervention effect PRD increased total C13-norisoprenoid content per berry.
- Mechanism The authors inferred that PRD-induced norisoprenoid concentration increases were independent of berry size and surface-to-volume changes.
