摘要: 对南方红豆杉扦插苗和实生苗光合生理特性比较研究结果表明，南方红豆杉扦插苗叶重、叶绿素a和b、叶绿素总量、CO2补偿点及净光合速率、硝酸还原酶活性均小于相应树龄实生苗。Abstract: The photosynthesis physiological characteristics of the seed seedlings and the cutting seedlings of Taxus chinensis var.mairei were analyzed. The results show that the total amount of hlorophyll, chlorophyll a and b, weight of leaf, CO2 compensation value, active of reductase nitrate and net photosynthesis in the seed seedlings are higher than those of the cutting seedlings.
