摘  要：
调查枇杷(洛阳青)的枝,叶,果器官中的7个性状对产量的关系,应用通径分析,确认各性状对单株产量的直接效应和间接效应,同时用逐步回归剔除其中不显著的性状,而得到最优回归预测式,它说明要提高批杷单株产量,在栽培技术上应增加总果数,全树叶数及结果枝上的总叶数。

摘  要：
10-or-15-year-old trees of Luo-yang-qing loquat located in Huang-yan,Zhejiang province were employed to study the relationship between yields and somegrowth and fruiting characters including the amount of yields(y),total one andtwo-year-old shoots(x_1),total leaves(x_2),number of bearing shoots(x_6),fruit(x_4),the leaves on the bearing shoots(x_5),total vegetative shoots(x_6)andthe leaves on vegetative ones per tree.Path coefficient is the partial regression coefficient treated With the variablestandardization.It can indicate the direct effect(direct path coefficrent)andindirect effect(indirect path coefficient)in relationship between the causes andeffects among the related variables.After rejection of some insignificant variables,the remainder is only 5 variables.Thus,Stepwise regression of the Variables leadsthe best regression equation.It can be applied to forecast the yield of per tree.It also shows that to raisethe yield,the development of the organs such as x_4,x_5 and x_2 should be promotedso as to increase their quantity.It is of instructive significance to some extentto the culture.
