华杂6号叶面积简易测定方法

Study on an easy measuring method of leaf area of Huaza 6(Brassica napus L.)

在直播条件下,研究了华杂6号的叶长、叶宽、长宽乘积与叶面积,单叶面积与整株叶面积的关系。结果表明,华杂6号的单片叶面积与叶长、叶宽、长宽乘积都呈幂函数关系,但单片叶面积与长宽乘积关系最密切,其次是叶宽,最后是叶长。单株叶面积与单片叶面积呈一元线性函数关系,但相关性最好的叶片所处叶位,随绿叶数的增加而降低。

Study on the correlation of leaf area and width and the correlation of the total leaf area of a plant its length, width, and the product of length and and a single leaf area of the plant were conducted on the condition of direct sowing by using Huaza 6. The results showed that, leaf area was correlated in power function with its length, width, and the product of length and width. The product of length and width had the closest relation to the leaf area, and followed by its width and length. The total leaf area of a plant was correlated in linear function with a single leaf area of the plant, but the leaf correlated to the plant leaf area the most lowered as the number of green leaves increased.
