【摘要】 1990-1992年,以‘巨峰’葡萄为试材,研究了整个浆果生长期间鲜重和体积与纵径、横经之间的关系。结果表明,‘巨峰’葡萄浆果鲜重和体积的增加随浆果横径的增长比随纵径的增长更具有规律性。浆果鲜重体积可以用以浆果横径为自变量的分段曲线回归方程来计算。鲜重和体积的计算方程为:yw=0．641X3,X≤1．000cm;yw=0．121+0．593X3,X>1．000cm和yv=0．002+ 0．628X3,X≤1．000cm;yv=0．202+0．563X3,X>1．000cm。更多还原

【Abstract】 Fresh weight, volume and diameter of ’Kyoho’ grape berry was measured during berry growth in 1990-1992 and relations among the parameters were studied. The results showed that increasing of berry fresh weight and volume followed with transverse diameter were much more measurable than with vertical diameter. Berry fresh weight and volume could be computed by separating curvilinear regression equation with independent variables of berry transverse diameter, of which the computing equation were yw = 0. 641 x3, x≤1. 000cm; yw = 0. 121 + 0. 593 x3, x>1. 000cm and yw = 0. 002 + 0. 628 x3, x≤1. 000cm, and yw = 0. 202 + 0. 563 x3, x> 1. 000cm, respectively.更多还原
