摘　　要：杉木雄性不育株与可育株叶绿素含量和硝酸还原酶活力的比较＊吕洪飞余象煜李平何福基关键词杉木、雄性不育株、叶绿素含量、硝酸还原酶活力、发育时期硝酸还原酶（ＮＲ）活力被认为是判断杉木（Ｃｕｎｎｉｎｇｈａｍｉａｌａｎｃｅｏｌａｔａ（Ｌａｍｂ．）Ｈｏｏｋ．）生...This paper deals with the study on the chlorophyll content(Ch C) and nitrate reductase (NR) activity in different developmental stages by comparing male sterile plant (MSP) with male fertile plant(MFP) of Cunninghamia lanceolate (Lamb.)Hook.The Ch C of MSP is significantly higher than that of MFP on fertile soil; otherwise,it′s lower than that of MFP.The Ch C of MSP declined with the decrease of soil fertility.Within the forest,the ratio of chlorophyll a and b of MSP is smaller than that of MFP.It shows that MSP is more tolerant than MFP .MSP is suitable to grow on more fertile soil.Before the second ten days of April,the NR activity of MSP is obviously weaker than that of MFP,showing that it has higher level of nitrogen fertilizer resistance.More fertilization may increase its Ch C,and promote its growth. In nutritive growth stage,the NR activity of MSP is significantly higher than that of MFP,showing that MSP has higher ability of nitrate assimilation and grows fast.
