摘要
利用回归方程法进行了红掌叶面积测定研究,结果表明:供试的2个红掌品种3种规格植株的叶面积与叶长、叶宽为参数的单双因子均有显著的相关性,相关系数(R2)均以叶长×叶宽为最大;经检验用叶长×叶宽作为参数建立回归方程,以其计算的理论值与实际值没有显著性差异,说明回归方程法属于比较实用的红掌叶面积调查方法。
This paper with linear regression analysis respectively on the leaf area, the length, the width of leaf as single and bi-factor in different varieties, different specifications of A nthurium andraeanum with the method of mathematieat statistics, it obtains respective linear regression equation of high correlation according to the length x the width of leaf, thus proved that it is high reliability for measuring leaf area in A nthurium andraeanum.
