摘　　要：以杜鹃红山茶(Camellia azalea)成熟叶片为材料,研究杜鹃红山茶叶长、叶宽、叶长×叶宽与叶面积的关系,结果表明:叶长、叶宽、叶长×叶宽与叶面积均呈直线相关,经F检验,差异极显著;所建立的6个回归方程的相关系数高于0.881 488,其中,y=-1 373.824+22.024x1+35.583x2为0.956 6、y=-391.205+12.056x1+0.361x3为0.952 2。所建立的6个回归方程均可应用于杜鹃红山茶叶面积的测算。Taking Camellia azalea mature leaves as tested materials,the relation of leaf length（x1）,leaf width（x2） and leaf length × leaf width with leaf area（y） was studied.The results showed that there was a linear correlation between leaf area and leaf length,leaf width and leaf length × leaf width.By F test,the difference was obvious.Correlation coefficients of six regression equations were higher than0.881 488,among them y =-1 373.824 ＋ 22.024x1＋ 35.583x2 and y =-391.205 ＋ 12.056x1＋0.361x3 reached 0.956 6 and 0.952 2 respectively.All of regression equations could be used in leaf area estimation of Camellia azalea.
