Predicting models of height and DBH，specific leaf area， crown volume and LAI for Feijoa sallow

Taking 5 years old Feijoa in Sichuan province as material，the predicting models of specific leaf area， crown volume and LAI for Feijoa were developed by using Excel and SPSS tools. The results showed that the predicting model of height and DBH was D=16.24H2 - 53.31H + 78.33；The specific leaf area model was，y=0.630x+0.333（x refers to the result of leaf major axis multiply leaf minor axis）；The crown volume predicting model was V=0.355×L1.825 ×H10.923×D-0.602×H0.916（L refers to crown length，H1 refers to crown height，D refers to DBH，H refers to total height）； The LAI model was LAI=-0.761H2+6.526H+0.187D2-1.187D-4.888（D refers to DBH，H refers to total height）. All of those models were evaluated and the accuracy were 91.65%，88.65%，92.01%. Therefore，the models were suitable for estimating the height and DBH，specific leaf area，crown volume and LAI for Feijoa.
