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.
According to the average value of observed data from 1991 to 1994, the correlations between fruit Vc and acid content of 44 grapefruit cultivars were studied. The linear equations, hyperbola, exponential function, power function, logarithmic function, S Type curve and quadratic polynomial curve, the quadratic polynomial Y = 32.12-135.18X + 50.43X ~ 2 (correlation index R = 0.868) is the most suitable regression equation. In addition, This regression curve showed relatively consistent, and further confirmed that there is a very significant and stable correlation between fruit VC and total acid content in the pomelo genotypes.
