摘要: 在位于吉林省东南部中朝交界地带的长白山北坡,选择了三块样地:小天池样地(海拔1800 m)、树线样地(海拔2000 m)、天文峰样地(海拔2325 m),测定了高山红景天的净光合速率、蒸腾速率,计算了表观量子效率和水分利用效率。光合速率和蒸腾速率以天文峰样地最高,树线样地次之,小天池样地最低。表观量子效率和水分利用效率则恰好相反,小天池样地最高,树线样地次之,天文峰样地最低。

Abstract: Three sample plots, which were Xiaotianchi (Alt. 1800 m), Tree Line (Alt. 2000 m) and Tianwenfeng (Alt. 2325 m), were selected from the north slop of ChangBai Mountain located on the Southeastern of Jilin Province. Net photosynthesis rate (Pn) and transpiration rate (Tr) of Rhodiola sachalinensis in three simple plots were measured, furthermore appear quantum yield (AQY) and water use efficiency (WUE) also were calculated correspondingly. The result showed Pn and Tr in Tianwenfeng plot were the highest, the second was in Tree Line plot, and the lowest was in Xiaotianchi plot. However AQY and WUE displayed the reverse trend, which of Xiaotianchi plot presented the highest value, Tree Line plot was the second and Tianwenfeng plot was the lowest.

Key words: Rhodiola sachalinensis, Gas exchange, ChangBai Mountain
