✓ located verbatim in the source · abstract, characters 1478–1776 Other claims from this paper (16) Intervention effect Shade-grown grapevines at 60% and 30% sunlight had significantly lower Pnsat, Rd and PARc than unshaded vines at flowering and veraison. Intervention effect Shade-grown grapevines at 60% and 30% sunlight had significantly lower PARsat than unshaded vines at flowering and veraison. Intervention effect The apparent quantum yield (φi) of shade-grown grapevines was significantly higher than in unshaded vines. Intervention effect At flowering, Pnsat of grapevines grown at 60% sunlight was about 62% of that of unshaded vines (0900-1100 h). Intervention effect At flowering, Pnsat of grapevines grown at 30% sunlight was about 54% of that of unshaded vines (0900-1100 h). Intervention effect At veraison, Pnsat of grapevines grown at 60% sunlight was about 81% of that of unshaded vines (0900-1100 h). Intervention effect At veraison, Pnsat of grapevines grown at 30% sunlight was about 65% of that of unshaded vines (0900-1100 h). Association The diurnal patterns of Pn, gs and ψ in grapevine leaves were positively correlated with PAR at both phenological stages. Intervention effect Shading significantly reduced leaf transpiration rate in the early morning during flowering. Intervention effect Shading left the calculated intercellular CO2 concentration (Ci) of grapevine leaves unaffected. Association Shading was associated with a decrease in specific leaf dry weight, leaf soluble carbohydrates and starch content of grapevine. Association Shading was associated with a decrease in total leaf area per vine, number of axillary shoots per cane and winter pruning weight. Mechanism The increase of φi, leaf chlorophyll content and the change to a more open canopy increased PAR trapping efficiency, indicating adaptability of the grapevine to low light. Association Vine yield and berry quality decreased linearly with increasing shade intensity in grapevine. Recommendation Grapevine management should ensure that most leaves receive approximately 700 to 900 µmol m-2 S-1 of PAR for most of the day during the crop cycle. Recommendation Factors that modify light availability at the canopy level must be evaluated to reduce risks of low photosynthesis, low yield and poorer grape quality.

✓ located verbatim in the source · abstract, characters 1899–1953 t0 “grapevine ”
✓ located verbatim in the source · title, characters 92–101 Other claims from this paper (14) Observation Leafroll infection reduced grapevine gas exchange. Observation At ripeness, stomatal conductance fell more than net assimilation. Observation Infected leaves had higher intrinsic water-use efficiency. Mechanism The declines in conductance and assimilation were not attributed to lower bulk water potential. Observation Maximum photosystem II quantum efficiency was unaffected by infection. Observation Effective PSII efficiency, electron transport and photochemical quenching decreased significantly. Observation Non-photochemical quenching increased significantly. Observation Virus infection reduced light-saturated CO2 fixation and carboxylation efficiency. Observation Apparent quantum yield of CO2 fixation was significantly higher. Observation Infection markedly reduced photosynthetic pigments, soluble sugars and proteins. Observation Starch and anthocyanins increased significantly under infection. Observation Leaf N, P, Ca, S and Fe concentrations significantly decreased. Observation Leaf K, Mg, B, Cu, Zn and Mn concentrations were unaffected. Observation Lower cluster weight contributed to yield loss. Intervention effect observed original result no effect not significant (as stated) measured Claim · model-written summary
