| 摘 要： | 目的]合理调控红麻的产量构成因素,提高红麻的纤维产量。方法]以纤维产量为参考数列,株高、茎粗、皮厚、笨麻率、干皮精洗率5个产量构成因素为比较数列,对8个红麻品种的纤维产量与产量构成因素进行灰色关联度分析。结果]红麻5个产量构成因素与红麻纤维产量的关联度大小顺序依次为:皮厚>株高>干皮精洗率>茎粗>笨麻率。关联度分析表明,在育种上,红麻应选育皮厚、植株高大的品种;在栽培上,应主攻皮厚,增加植株高度,减少笨麻率,协调好产量构成因素之间的关系。结论]红麻的纤维产量与皮厚、株高、干皮精洗率等产量构成因素密切相关。

| Abstract: | Objective] The aim was to reasonably regulate the yield components of kenaf and enhance its fiber output.Method] With fiber outputs as reference number series,5 yield components of plant height,stem thickness,bark thickness,unavailable rate and fiber rate as comparison number series,the grey correlation degree analysis was conducted on the fiber outputs and yield components of 8 kenaf varieties.Result] The correlation degrees between the 5 yield components and fiber output of kenaf in order were bark thickness > plant height > fiber rate > stem thickness > weak kenaf rate.The correlation degree analysis showed that the varieties with thick bark and big plant should be selected in the breeding of kenaf.In cultivation,the research should be mainly on bark thickness,increasing plant height,reducing weak kenaf rate and coordinating the relationships among yield components.Conclusion]The fiber output of kenaf had close relationship with the yield components such as bark thickness,plant height and fiber rate. |
