摘　　要：为了增大濒危植物海南粗榧的种群数量,对海南粗榧进行就地及迁地抚育研究,结果表明:1)在就地抚育过程中,适当增加光照以及增施肥料对海南粗榧株基径的增长有显著影响,对其叶绿素增长有显著影响,并且显著降低SOD酶活,缓解其逆境条件。2)迁地抚育过程中,适当增加光照强度对海南粗榧的生长有显著的促进作用;以营养土作为基质的海南粗榧幼苗叶片叶绿素也有极显著增加;除了降低光照对SOD酶活性增加有影响外,其他环境因子都会降低SOD酶活性。3)人工抚育手段能很好地促进海南粗榧幼苗的生长。In-situ and ex-situ conservation of the endangered plant Cephalotaxus mannii seedlings was studied in this present paper in order to increase its population number.And the results show：（1） increasing light intensity and fertilizer appropriately in the process of in-situ conservation affects significantly the growth of stem base diameter and the content of chlorophyll of the seedlings,and decreases the activity of SOD and eases their stress conditions.（2） Increasing light intensity in the process of ex-situ conservation can promote the growth of seedlings significantly and the content of chlorophyll of the seedlings leaves which cultured at the nutrition soil increased significantly.And in the process of ex-situ conservation,reducing the light intensity increases the activity of SOD and other environmental factors can reduce the activity of SOD.In-situ and ex-situ conservation can make C.mannii seedlings grow better.
