Interactions between light and growing season temperatures on, growth and development and gas exchange of Semillon (Vitis vinifera L.) vines grown in an irrigated vineyard

► We measured high-light-high temperature affects on vine growth and development. ► Shoot phenology was unaffected but fruit and leaf growth increased by high-light. ► Fruit ripening delayed by low-light but increased by high temperature. ► Sun/shade attributes of photosynthesis accounted for changed growth patterns.
