- Intervention effect Water stress reduced leaf net assimilation rate by 60% in Tannat versus well-watered plants.
- Intervention effect Water stress reduced leaf net assimilation rate by 60% in Duras.
- Intervention effect Water stress reduced stomatal conductance by 64% in Tannat.
- Intervention effect Water stress reduced stomatal conductance by 46% in Duras.
- Association Berry fresh mass components varied significantly by cultivar and water availability.
- Observation Tannat seed, skin and flesh represented about 6%, 12% and 82% of berry fresh weight.
- Observation Duras seed, skin and flesh represented about 3%, 12% and 85% of berry fresh weight.
- Association Seed, skin and flesh proportions varied with berry size.
- Intervention effect Water stress increased total seed mass per berry.
- Association Anthocyanin content and seed tannin concentration varied by variety and water stress treatment.
- Association Seed tannin varied more with berry size and less with vine water status than skin tannin or anthocyanin.
- Intervention effect Water stress had a positive effect on anthocyanin content in Tannat.
- Association Seed and skin tannin concentrations decreased as berry fresh weight rose.
