摘　　要：以兴安桧为试验材料,研究了不同遮荫处理对其叶绿素含量和保护酶活性的影响。结果表明:随着遮荫程度的增加,叶绿素a、叶绿素b、叶绿素a+b含量增加,SOD活性下降,POD活性呈现先升高后下降的趋势,但均显著高于对照,MDA含量显著低于对照。Effects of different shading treatments on chlorophyll and protective enzyme activities of Sabina davurica（Pall.）Ant.were studied.The results showed that with the strengthening of shading treatment,the content of chlorophyll a,chlorophyll b and chlorophyll a＋b increased;SOD activity decreased;POD activity showed a first increasing and then falling tendency,and it was obviously higher than check;the content of MDA was obviously lower than check.
