测定果实生长量的方法很多,现介绍下面几种:1.纵、横径测量法用千分卡尺直接测量果实的纵、横径,用纵、横径增长的曲线来表示果实增长的规律。对于近圆形的果实,还可取其纵径和横径的平均值为果实直径上 D,代入球体体积计算公式 V=1/6πD~3,便可求出果实体积及果形指数。此法观测时简便易行。2.周长测量法
There are many ways to determine the amount of fruit growth. The following is introduced: 1. Vertical and horizontal diameter measurement The vertical and horizontal diameter of the fruit is measured directly with a micrometer caliper to show the law of fruit growth with the curve of vertical and horizontal diameter growth. For the nearly circular fruit, but also take the average diameter and diameter of the diameter of the fruit on the D, into the sphere volume calculation formula V = 1 / 6πD ~ 3, you can find the fruit volume and fruit shape index. This method is simple and easy to observe. Perimeter measurement method
