对30份不同来源南荻种质资源的9个农艺性状(叶茎比、茎壁厚、株高、节数、最大节长、茎粗、单株重、分枝数和分蘖数)和6个品质性状(含水量、灰分、半纤维素、纤维素、木质素和热值)进行综合评价,结果表明:(1)南荻种质资源农艺性状和品质性状的变异系数变化范围为4.15%~75.02%;(2)主成分分析表明,前5个主成分因子解释了88.68%的变异源,第1主成分因子载荷最高的性状是株高、分蘖数、茎粗,说明产量及其构成因子是南荻的主要变异来源;(3)聚类分析表明,30份南荻种质可划分为3大类,第Ⅰ类群由8份来自洞庭湖地区的种质组成,第Ⅱ类群由14份来自鄱阳湖和长江中下游地区的种质组成,第Ⅲ类群由8份来自长江下...

The present study comprehensively compared and evaluated nine agronomic traits (stem/leaf ratio, culm wall thickness, plant height, node number, internode length, stem diameter, plant weight, shoot number, nodal tiller number) and six energy-quality traits (water content, ash content, cellulose content, hemicellulose content, lignin content, net caloric value) of 30 Miscanthus lutarioriparius accessions. The results showed that (1) M. lutarioriparius has a wide genetic variation as expressed by the large coefficient variation (CV) of the above 15 traits of 4.15%~75.02%; (2) these variations we...
