Other claims from this paper (12)
- Intervention effect Water deficits during the early season tended to affect yield more negatively than deficits applied between pea size and harvest.
- Association Yield reduction was associated with reduced bunch differentiation, berry shed and smaller berries.
- Intervention effect Water deficits induced after flowering (T4) significantly reduced berry size.
- Intervention effect Water deficits had no significant effect on juice sugar content.
- Intervention effect Water deficits had no significant effect on total titratable acids.
- Intervention effect Significant browning of dipped raisins from TS and T6 grapevines occurred during some seasons compared with continued irrigation.
- Intervention effect Water deficits between pruning and budbreak significantly reduced yields compared with continued irrigation.
- Intervention effect Low relative humidity and dry soil delayed budbreak of Sultanina grapevines after harvest.
- Intervention effect Low relative humidity and dry soil stimulated excessive shoot growth after harvest.
- Intervention effect Cane mass was significantly higher under low relative humidity and dry soil than under irrigation at 60% PAW depletion.
- Intervention effect Neither water deficits nor shoot regrowth after harvest had any effect on cane starch content at pruning.
- Intervention effect Water stress in the pre-harvest phenological phases was too short to significantly affect vegetative growth.
