Other claims from this paper (8)
- Intervention effect Irrigated vines had about 30% higher stomatal conductance than drought-stressed vines.
- Intervention effect Drought stress reduced cluster fresh mass by 18%.
- Intervention effect Drought stress reduced berry fresh mass by 15%.
- Intervention effect Drought stress reduced skin fresh mass by 9%.
- Intervention effect Chitosan application did not significantly affect stomatal conductance, yield or berry ripening parameters.
- Intervention effect The interaction of irrigation and chitosan reduced stomatal conductance only in drought-stressed vines.
- Observation Water restrictions affected stomatal conductance and yield components without compromising berry quality.
- Mechanism The authors suggest chitosan spray at veraison may act as a short-term antitranspirant without affecting vine yield or berry quality.
