本文在对荠菜(板叶型)产量和其相关的八个性状进行相关和回归分析的基础上,明确了荠菜产量构成性状为单株叶数、叶片鲜重和叶柄鲜重,建立了产量构成三因素对产量的三元回归方程(?)=-5.6237+0.3753x_1+9.5734x_6+1.3425x_8,并作了产量主要构成性状对产量的通径分析。
Based on the correlation and regression analysis of the yield and the related eight traits of shepherd’s purse (Plutella xylostella L.), the yield traits of Shepherd’s pursee were determined as the number of leaves per plant, the fresh weight of leaves and the fresh weight of petiole, and the yield components The ternary regression equation (?) = - 5.6237 + 0.3753x_1 + 9.5734x_6 + 1.3425x_8 of the three factors on the yield, and made a path analysis of the yield of the main constitutive characters.
