摘　　要：芒属(Miscanthus)植物作为当今最具开发利用价值的纤维素生物质能源植物之一,受到世界上许多国家的广泛关注。中国是芒属植物的分布中心,有着极其丰富的种质遗传资源,这为我国芒属植物的研究利用提供了得天独厚的资源优势。本研究收集来自全国10个省份的30份不同生态型野生芒资源,利用细胞压片和流式细胞仪技术进行染色体数目和倍性的鉴定,以期为我国野生芒种质资源的遗传育种和利用奠定基础。结果表明,30份种质的染色体数目均为2n=2x=38,且均是二倍体。Miscanthus is one of the most important plant genus for fiber biomass development which has drawn the keen attentions throughout the world. China is one of the origins of Miscanthus with wide and abundant distribution and highly genetic diversity. Studies of Miscanthus germplasm will facilitate development of bioenergy industry in China. The ploidy in total of 30 accessions of M. sinensis collected from ten provinces of China was identified using optical microscope and flow cytome try. The results showed that all thirty accessions were diploidy with a cytotype of 2n =-2x=-38, suggesting that diploid may be the major cytotype for wild Miscanthus sinensis in China.
