| 摘 要： | 本文对19个国内外纤用亚麻品种（系）单株茎重的构成因素进行相关分析和通径分析,结果表明,茎粗、株高、工艺长度与单株茎重成极显著的正相关.经过通径分析可看出,茎粗、株高、分茎数、着粒数4个因素对亚麻单株茎重的变异起主要的决定作用,通径系数为0.92601,剩余通径系数为0.27200.

| Abstract: | The result of both correlation analysis and path analysis for the composing factors of the stem weight per plant of 19 flax varieties is:the stem wideth,the plant length,and crafter length is positive correlation,the stem wideth,the plant length,and number of stem and seed per fructification is factors which influence the the stem weight per plant most,the path coefficient is 0.92601 and the path coefficient of residual is 0.27200. |
