【摘要】 为了对红麻的茎粗和出麻率的关系有一个更清晰的了解,并为以后的红麻育种和栽培提供更好的依据,采用方差、表型和回归分析的方法,对‘福红992’茎粗与其出麻率之间的关系进行研究。结果表明:茎粗对出麻率的影响达极显著或显著水平,二者表型呈抛物线变化,红麻‘福红992’的最佳茎粗范围为1.5~2.0mm。对实验数据进行非线性回归分析发现,指数模型和多项式模型拟合程度较高,相关系数分别为0.9837和0.9310。更多还原

【Abstract】 The aims were to study kenaf stem diameter and Bark rate relation and provide a better basis for the subsequent kenaf breeding and cultivation. The correlation of stem diameter and Bark rate of‘Fuhong 992’ was studied by the analysis of Variance, phenotype and regression. The results showed that stem diameter had significant or highly significant effect on Bark rate and there is parabolic relationship between the two factors in phenotype. The bark rate of‘Fuhong 992’was the best when stem diameter range was 1.5 mm to 2.0 mm. According to the data from experiment, using the method of nonlinear regression analysis and finding that index model and polynomial model had high fitting degree. The related coefficients were 0.9837 and 0.9310.更多还原
