摘要
落叶前的巨峰葡萄(红富士)单叶面积(Y)为62.91cm^2±3.13～3.27cm^2,分别与叶中脉(X_1)、两侧脉(X_3,X_2)以及叶柄长(X_4)呈显著直线相关,r=0.9039～0.9440,Y=-29.78+0.70X_1+3.76X_2+6.86X_3+4.70X_4,R=0.9564。其作用大小依次为侧脉长>侧脉长>叶柄长>中脉长。
Before abscission,the individual leaf area (Y,LA) of grape ' Kyoho' (Vitis vinifera L. X V. labrusca L. cv. Red Fuji) was found significantly correlated with the lengths of the foliar midvein (x1),the two lateral veins (x2,x3),and the petiole (x4)respectively. The leaf area estimated from simple linear measurements accounts for 62. 91±3. 13~3. 27 cm2. All of these parameters present a closely multiple correlation with the LA y= - 29. 78 ± 0. 70x1 ± 3. 76x2 ± 6. 86x3 ± 4. 70x4,R = ± 0. 9564 ), whose effects can be represented by the partial correlation coefficients in the model as x3>x4>x2>x1.
