| 摘 要： | 根据1991-1994年连续4年观测资料的平均值,对44个柚品种果实Vc与酸含量的相关关系,通过计算机编程进行了直线方程、双曲线、指数函数、幂函数、对数函数、S型曲线和二次多项式曲线等8种常见方程式配合,确定了二次多项式Y=32.12-135.18X 50.43X~2(相关指数R=0.868)为其最适合的回归方程.另外,各年份间这种回归曲线图表现相对一致,更进一步证实柚品种基因型中果实VC与总酸含量之间确实存在着一种极显著而稳定的相关关系.

| Abstract: | Based on four years'data in 1991 - 1994, the regression model was studied between Vc and acid contents in the fruits of 44 pummelo varieties. After fitting 8 kinds of conventional regression equations by computer programing,quadric polynomial curve Y = 132.12 - 135.18X 50.43X2 (R =0.868**)was ascertained as the most suitable regression equation. The identity of regression graphs among 4 years showed that there was a stable and significant correlation between Vc and acid contents in pumello varietis. |
