Genotypic Difference in Phosphorus Uptake and Utilization in Ramie
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 germplasms 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 Lengshuijiang and wild ramie of Changsha.
