不同苎麻品种(系)茎秆抗折力和植株性状的差异及其相关性
|
摘要
以2014～2015年国家苎麻品种(系)生产试验的7个品种(系)为研究对象,研究了三麻成熟期7个苎麻品种(系)在植株性状、茎秆抗折力、木质素含量差异及各测试指标间的相关性。结果表明:不同苎麻品种(系)间在株高、茎粗、壁厚、茎段重量、木质素含量及抗折力方面差异显著。0501株高、茎粗、壁厚、茎段重量和抗折力均列第一位。在茎秆木质素含量方面,G59最高;在皮厚方面,中苎1号最厚;抗折力方面,0501、NC03、中苎1号表现较高。相关分析表明,抗折力与株高、茎粗和壁厚呈显著正相关,与茎段重量呈极显著正相关(相关系数为0.960),与皮厚、木质素含量间相关性未达到显著水平。
Six varieties and control variety Zhongzhu NO.1 were selected as materials to investigate the differences in breaking resistance and other plant characters such as plant height,weight of stem segment,lignin content of stem,stem diameter,wall diameter,fresh bast thickness,etc. Relationships among these traits were studied using the correlation analysis. The results showed that 0501 ranked the first in plant height,stem weight,stem diameter and breaking resistance. G59 had the highest lignin content of stem,and Zhongzhu NO.1 had the thickest fresh bast thickness among all varieties. Breaking resistance of 0501,NC03 and Zhongzhu NO.1 was relatively higher than other varieties. Correlation analysis showed that breaking resistance was significantly correlated to the plant height,stem diameter and wall diameter,extremely significant to weight of stem segment,whereas no significant correlation with fresh bast thickness and lignin content of stem.
