Establishment of Regressive Equation for Leaf Area of Camellia azalea

Abstract

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.
