摘　　要：本文对杉木［Ｃｕｎｎｉｎｇｈａｍｉａｌａｎｃｅｏｌａｔａ（Ｌａｍｂ）Ｈｏｏｋ］的雄性可育株与不育株进行了硝酸还原酶活力和叶绿素含量的比较研究。结果表明：不育株的叶绿素含量高于可育株的４４．７％，这与不育株生长较快相符。而不育株的ＮＲ活力则为可育株的６８．５％。The authors approach to the nitrate reductase activity and chlorophyll content by comparingmale sterile plant with male fertile plant in Cunninghamia Lanceolata (Lamb) Hook. The chloro-phyll content of male sterile plant is 44.7%higher than that of male fertile plant. As a result,male sterile plant grows faster than male fertile plant.But the NR activity of male sterile plant isonly 68.2%of that of male fertile plant
