Abstract

ABSTRACT: Phosphorus (P) is one of nutrients essential for plant growth. The differences in P content, accumulation, and distribution among 98 rapeseed ( Brassica napus ) varieties with different P use efficiency for grain production (PUEg) were studied. The results showed that there were highly significant differences in P contents of the whole plant and various organs among different rapeseed varieties. Furthermore, PUEg had significantly negative correlations with P accumulations in whole plant, stems, shells, and seeds. The correlation analysis showed that the correlation coefficient of PUEg and P distribution ratio in stems was smaller, and it was significantly negatively correlated in shells, while it showed highly positive correlations in seeds. It indicated that P content in rapeseed plant stems and shells appeared to be transported into seeds to increase P distribution in seedpods at the late maturity stage, which could help improve PUEg.
