ABSTRACT Vegetative and reproductive growth responses of vineyard-grown Vitis vinifera cv. Semillon vines to canopy temperatures were followed. Canopies were controlled at means of 29.8°C, 31.5°C and 32.7°C. Stem and leaf growth were affected; length and canopy leaf area was maximal in the warmest treatment and smallest in the coolest treatment. Accumulation of biomass of leaves, stems and bunches was highest in the coolest treatment and lowest in warm conditions. Berry expansion was affected by treatment temperatures but most reduced in the warm treatment, whereas accumulation of sugar in the berries was highest in the coolest treatment. There were treatment differences in yield, with a marked reduction in the warm treatment. Clearly, there were detrimental growth responses to the higher temperatures. The temperature differential between treatments of 3°C was comparable with what might occur with climate change and the study shows such a difference can be detrimental to vine growth and development.

树冠温度的微小差异会影响赛美蓉在葡萄园中的表现吗？

摘要 葡萄园种植的 Vitis vinifera cv. 的营养和生殖生长反应。赛美蓉葡萄树的树冠温度随之而来。檐篷控制在 29.8°C、31.5°C 和 32.7°C。茎叶生长受到影响；长度和冠层叶面积在最暖处理中最大，在最冷处理中最小。叶、茎和束的生物量积累在最冷处理中最高，在温暖条件下最低。浆果膨胀受处理温度的影响，但在温暖处理中减少最多，而在最冷处理中浆果中糖的积累最高。产量存在处理差异，暖处理显着减少。显然，对较高温度存在有害的生长反应。
