摘要
对引进山东的17个茶树品种(群体种)的叶片进行了气孔导度、蒸腾特性的观测研究,得出:茶树品种不同的气孔导度日变化总体趋势基本一致,均呈单峰型曲线;随着株龄的增加,茶树各品种的气孔导度均有不同程度的增加.不同品种茶树蒸腾速率变化趋势与其气孔导度的相同,并随着株龄的增加,各品种茶树的蒸腾速率均有不同程度的增加.综合各项指标从中筛选出适宜在当地推广的茶树品种.
Based on the observation and study on stomatal conductance and transpiration characteristic of tea leaves, which are sampled from 17 varieties of tea plants induced in Shandong province, some new conclusions are presented. Stomatal conductance of different kinds of tea plant all incr~,~se by different degree with plant ages growing, and its general daily changing tendency is generally unanimous and is represented by single-apex curve. Changing tendency of transpiration rates is just same as that of the stomatal conductance. Some tea plant varieties that are suitable for local popularization are selected based on the indexes being synthesized.
