2种不同类型的尖叶胡枝子光合-光响应特性研究
Study on photosynthesis and photo-response characteristics of two types of Lespedeza hedysaroides
摘要
Abstract
The paper studied the chlorophyll contents, photosynthesis and photo-response characteristics of two different types of L. hedysaroides such as yellow green type and dark green type. The results showed that the chlorophyll contents of two types had significant differences. The maximum net photosynthetic rate(Amax), dark respiration rate(Rd) and apparent quantum yield(AQY) of dark green type of L. hedysaroides were higher than the yellow green type, and the apparent light compensation point(LCP) and light saturation point(LSP) of dark green type were lower than that of the yellow green type. The light radiation net photosynthetic rate(Pn), interceller CO2 concentration(Ci), stomatal conductance(Gs), transpiration rate(Tr), water use efficiency(WUE) and leaf temperature of the two types showed different responses to the photosynthetic available radiation flux density(PPFD) to some extent.关键词
