摘　　要：通过测定大叶枸杞(Lycium chinense Mill.)相关形态指标和部分生理指标,研究了其在不同林分郁闭度香樟(Cinnamomum camphora L.)林下的生长状况。结果表明,林分郁闭度越高,大叶枸杞长势越好,成活率越高,叶绿体色素含量也随之增加;但随着林分郁闭度增高,叶片可溶性糖含量逐渐降低。Through measurement of morphology and partial physiology indexes of Lycium chinense Mill. , its growing status under different canopy density of Cinnamomum camphora L. were studied. The results showed that, the higher the canopy density was, the better the growth vigor of Lycium chinense Mill. was, and the higher survival rate was. Thus, the contents of chloroplast pigment increased. However, with the increase of canopy density, the contents of soluble sugar decreased.
