| 摘 要： | 试验通过对48个黄瓜品种9个有关性状因素进行相关分析,找出了与黄瓜弯曲相关的性状。经主成分分析挑选出果柄长、果长、种腔/果粗3个主要因子与黄瓜果实的曲直性关系密切,并进行多元回归分析,证明3个主要因子与弯度呈线性关系,建立了黄瓜果实曲直度的数学表达公式。

| Abstract: | The experiment carried on the correlation analysis of 48 cucumber varieties and 9 factors related to the traits of cucumber, and discovered the cucumber curving on related character. After the principal components analysis, selected 3 main factors of fruit stalk length, fruit length, fruit cavity/fruit diameter which were closely related to the cucumber fruit bending traits, and carried on multiple regression analysis. The study proved that there was a linear relationship between 3 main factors and the bending, and established the mathematical expression formula about different degrees of bending in cucumber fruit. |
