摘　　要： 采用回归的方法 ,对 11个节瓜品种 (品系 )建立了叶面积与叶长、叶宽和两者乘积的线性回归和幂函数回归方程。结果表明 ,各节瓜品种叶面积与相应指标呈极显著回归关系 ,通过比较选择确定一元线性回归和幂函数回归方程较为适用于叶面积的估算 ,同时还得出了各品种通用的回归方程。 Liner and exponent function regression equations were established by leaf area with leaf length, leaf width and the product of the both with 11 chieh-qua(Benincasa hispida Cogn. var.chieh-qua How.)cultivars. The results showed that there were significant correlationship between leaf area of each chieh-qua cultivar and its related factors. One-factor liner and exponent function regression equations were considered suitable to estimate leaf area. And a universal regression equation for all cultivars was given in the report.
