摘要
在田间条件下,比较金边黄杨与大叶黄杨光合生理特性的结果表明:(1)金边黄杨的叶绿素含量极显著低于大叶黄杨,类胡萝卜素和花色素苷含量无显著差异;(2)金边黄杨的光合能力显著低于大叶黄杨,表观量子效率、羧化效率分别为大叶黄杨的54%和50%;(3)二者的净光合速率日变化均为单峰曲线,金边黄杨净光合速率和蒸腾速率日积分值分别为大叶黄杨的60%和75%。
Abstract The photosynthetic characteristics of Euonymus japonicus L. f. aureo-marginatus Rehd. and Euonymus japonicus L. in the fields were studied. The results showed that： （1） The chlorophyll contents of E. japonicus L. f. aureo-marginatus Rehd. was much lower than that of E. japonicus L., but the carotenoid and anthocyanin contents were not significantly different between them; （2） The photosynthetic ability of E. japonicus L. f, aureo-marginatus Rehd. was obviously lower than that of E. japonicus L., apparent quantum yield （AQY） and carboxylation efficiency （CE） in E. japonicus L. f. aureo-marginatus Rehd. were 54% and 50% of those in E. japonicus L., respectively; （3） Both of the diurnal variation of Pn were ＂single peak curve＂, the diurnal calculus value of Pn and Tr in E. japonicus L. f. aureo-marginatus Rehd. were 60% and 75% of those in E. japonicus L., respectively.
