苹果果实体积和重量测定方法的研究

Study on Measuring Methods of Apple Fruit Volume and Weight

本试验对苹果3个品种的果实体积和重量的测定方法进行了研究,建立了测定各品种果实体积和重量的最优多元线性回归方程及幂函数方程。另一分析结果表明:相关回归法、圆球体积法均与排水法测定果实体积的结果差异不显著,但圆球体积法的误差较大。

Linear multiple regression equations and power equations for measuring fruit volume and weight of three apple varieties were established. Further analysis indicated that though the error of global method was greater than the method of correlation and regression and that of drain off water when using them to measure the fruit volume, there were no significant diversities between the three methods said above.
