摘要
在长沙夏季高温条件下,以翠玉猕猴桃为供试材料,研究不同节位猕猴桃叶片的光合特性。结果显示:不同节位叶片的冠幕PAR、Tair日变化趋势均为单峰曲线型,峰值出现在13∶00左右;RH和Ca的日变化均呈午间低谷型,不同节位叶片的冠幕微气候均无显著性差异。中部叶片的光合能力最强。
Under the high temperature conditions in summer of Changsha, the kiwifruit variety Cuiyu was chosen as material to study photosynthesis characters of kiwifruit leaves at different nodes. The result showed that the daily vanation of PAR and Tair of leaves at different nodes all showed a single peak curve, and the peak showed at 13：00 during a day; the daily variation of RH and Ca all showed a noon trough trend; the canopy microclimate of leaves at different nodes had no significant difference. The photosynthetic capability of middle leaves was the strongest.
