| 摘 要： | 对10个苎麻种质磷利用效率进行研究,以筛选出磷利用效率较高的种质.采用旱地试验、坡地试验、温室盆栽试验相结合,测定了不同种质的农艺性状、地上部干重和地上部磷含量,运用聚类分析方法,对10个种质磷利用效率进行分类.综合3个试验结果,可将10个品种分为3类：磷素吸收利用较强的是浏阳野麻、中苎1号、湘苎XB、湘苎X3、湘苎X1,磷素吸收利用能力中等的是湘苎X2、湘苎3号、多倍体1号,磷素吸收利用能力较差的是冷水江野麻、长沙野麻.

| Abstract: | The phosphorus use efficiency of ten ramie germplasms was studied by experiments in dry flatland, slope land and pot in greenhouse to screen germplasms with high P efficiency. The agronomic traits, dry weight and P content of shoot were measured, and then 10 ramie germplasms were classified by cluster analysis. The results showed that 10 ramie germ- plasms could be divided into three kinds, the higher phosphorus use efficiency germplasms were wild ramie of Liuyang, Zhongzhu No. 1, Xiangzhu XB, Xiangzhu X3 and Xiangzhu X1, the medium phosphorus use efficiency germplasms were Xiangzhu X2, Xiangzhu No. 3 and Tri - 1, and the lower phosphorus use efficiency germplasms were wild ramie of Leng- shuijiang and wild ramie of Changsha. |
