摘要
对我国 3 6个陆地棉主栽品种的 1 2个纤维品质性状进行了相关分析和通径分析 ,结果表明 :气流纺品质指标与比强度、长度、细度间呈极显著正相关关系 ,与成熟度间呈极显著负相关 ,环锭纺缕纱强力与比强度、长度、反射率及伸长率间呈极显著正相关 ,与短纤维指数、黄度间呈极显著负相关 ;比强度对气流纺品质指标、环锭纺缕纱强力的直接作用最大 (正向作用 ) ,单强的直接作用次之 (负向作用 )。
The correlation analysis and path analysis of twelve fibre quality characters of 36 mainly-cultivated upland cotton varieties in China are conducted,the results show that there are significant positive correlations at the 0.01 probability level between the quality index of open-end spun yarn and break length, length, thin degree, there is significant negative correlation at the 0.01 probability level between the quality index of open-end spun yarn and maturity. The strength of ring spun yarn has significant positive relation to break length, length, reflecting rate and lengthening rate, and significant negative relation to index of short fibre and yellow degree at the 0.01 probability level. The break length has the largest positive direct function on the quality index of open-end spun yarn and strength of ring spun yarn, and fibre strength has the largest negative direct function on them.\;
