摘要:
原材料是夏布衣着用的重要限制因素,评价、筛选优异的苎麻品种资源,是制造优质夏布衣料的基础。本研究以30份苎麻品种(种质)为实验材料,浏阳鸡骨白、日本昭和村麻为对照,比较单纤维直径和强力,发现有14个品种均优于对照。对30个苎麻品种及CK1的8个指标进行差异性分析、相关性分析、主成分分析和聚类分析,发现不同品种之间差异极显著,且部分指标之间存在极显著的相关性,30个品种及CK1可分为3类,评价指标可简化为6个。通过隶属函数分析法筛选出了优于对照CK1的品种有大庸黄壳麻(编号18)、割麻(编号11)和乐昌黄皮苎(编号3)。

Abstract:
The quality of grass cloth for clothing is limited by the raw material ramie used for making the cloth. The evaluation and selection of excellent resources of ramie varieties are the basis for the production of high quality grass cloth materials. In this study, 30 ramie varieties (germplasms) were used as experimental materials, and Liuyangjigubai and Ribenzhaohecunma were used as controls. By comparing the diameter and strength of individual fibers, 14 ramie varieties were found to be superior to the controls. Difference analysis, correlation analysis, principal component analysis and cluster analysis were carried out on 8 indexes of the 30 ramie varieties and CK1. Significant differences among the varieties, and among some of the indexes were found. The 30 varieties and CK1 could be divided into 3 categories, and the number of evaluation indexes could be simplified to 6. The varieties better than the control CK1, selected by the method of membership function analysis, were Dayonghuangkema (No. 18),including Gema (No. 11)and Lechanghuangpizhu(No. 3).
