摘要

摘要: 分别对浙江西天目山濒危植物天目铁木(Ostrya rehderiana)和羊角槭(Acer yangjuechi)进行叶片气体交换参数日动态测定，探讨其光合与蒸腾作用的影响因素，比较光能利用效率和水分利用效率.结果显示，天目铁木的净光合速率日动态有午休现象；当光合有效辐射没有显著差异时，天目铁木的净光合速率显著大于羊角槭(p0.05)，与其林冠层阳生环境相适应；二者光能利用效率日变化无明显差异，但弱光条件下，羊角槭的光能利用效率高于天目铁木(p0.05)，与其林下层耐阴植物的特性相符；二者的水分利用效率日动态不同，羊角槭高于天目铁木(p0.05)，表明羊角槭蒸腾活动降低而导致.

Abstract: In order to compare the differences of gas exchange between suntolerant and shadetolerant plants, diurnal variations in photosynthetic and transpiration indices were measured using LI6400 portable photosynthesis system in two endangered species, Ostrya rehderiana Chun (suntolerance) and Acer yangjuechi Fang et P. L. Chiu (shadetolerance). Our results showed that O. rehderiana was a bimodal curve in diurnal change of photosynthesis rate (Pn), while A. yangjuechi was a unimodal curve. A. yangjuechi had a higher light use efficiency (RUE) than O. rehderiana under a relatively weak light (p0.05), suggesting A. yangjuechi had an increased net photosynthesis rate (P n) in weaker light conditions, e.g. under a longterm shade circumstance. The water use efficiency (WUE) was also higher in A. yangjuechi than in O. rehderiana (p0.05). This indicated A. yangjuechi had a lower transpiration in shaded conditions.
