摘要
对樟树、大叶女贞、观光木、山杜英、乳源木莲和乐昌含笑6种阔叶林的叶性状进行了研究。结果表明,樟树叶长和叶宽成显著相关,而其他5种树种的叶长和叶宽成极显著相关,相关系数的顺序为观光木>大叶女贞>乐昌含笑>山杜英>乳源木莲>樟树。各树种的叶长和叶面积成极显著相关,相关系数的顺序为乐昌含笑>观光木>山杜英>乳源木莲>大叶女贞>樟树。各树种的叶宽和叶面积也成极显著相关,相关系数的顺序为观光木>乳源木莲>樟树>乐昌含笑>大叶女贞>山杜英。各树种的叶面积和叶干重成极显著相关,相关系数的顺序为观光木>山杜英>大叶女贞>乳源木莲>樟树>乐昌含笑。
A study was carried out on the leaf treats within six broadleaved stands, namely, Cinnamomum yuyuanensis, and Michelia chapensis. The results showed that the significant and very significant correla- tion between leaf length and leaf width existed in C. camphora stand and other stands, respectively, and the order of correlation coefficient was T. odorum〉 E. sylvestris〉 L. lucidum ） M. yuyuanensis〉 C. camphora〉Michelia chapensis. There was a very significant correlation between leaf length and leaf area with a correlation coefficient order of Michelia chapensis 〉 T. odorum〉E, sylvestris） M. yuyuanensis L. Jucidum〉 C. camphora〉Michelia chapensis. The strong significant correlation between leaf width and leaf area was also apparent with a correlation coefficient order of T. odorum 〉 M. yuyuanensis 〉 C. camphora 〉 Michelia chapensis 〉 L. lucidum 〉 E. sylvestris. The significant correlation was found be- tween leaf area and leaf dry weight with a correlation coefficient order of T. odorum）E, sylvestris〉L. lucidum〉M, yuyuanensis〉C, camphora〉M, chapensis.
