摘要/Abstract

摘要： 通过遮光实验研究了裂叶沙参(Adenophora lobophylla)和泡沙参(A. potaninii)叶片的气孔行为,比较了不同遮光处理对裂叶沙参和泡沙参气孔的生理特性以及生态适应的影响。结果表明:裂叶沙参对不同遮光处理的适应性较差,相反,泡沙参具有较强的适应性和抗逆性;在自然光照和轻度遮光条件下,中午时泡沙参叶片的气孔开度逐渐减小和部分气孔关闭;裂叶沙参光合作用的非气孔限制占主要地位,泡沙参光合作用的气孔限制较明显。

关键词: 裂叶沙参, 泡沙参, 遮光处理, 气孔行为

Abstract: The stomatal behavior of both Adenophora lobophylla and A. potaninii was studied in this paper by means of shading experiment. With effect of different shade treatment on the stomatal physiological character and ecological adaptation of both A. lobophylla and A. potaninii being compared.The main results are as follow: compared with A. lobophylla, A. potaninii has showed strong of drought resistant and adaptive ability for different shade treatment. The stomatal open of blades for A. potaninii cut down gradually and part of the stomata closure in noon in nature light and light shade. The stomatal restriction for A. potaninii in photosynthesising was more evident, so was the non-stomatal restriction in photosynthesising for A. lobophylla.

Key words: A. lobophylla, A. potaninii, shade treatment, stomatal behavior
