Abstract
A field trial was carried out to study the effect of different P supply on the grain yield and P acquisition through utilization of eight rice cultivars. Results showed that there were significantly genotypic variations in rice grain yield, P utilization efficiency and shoot P accumulation at different growth stage under two different levels of P supply. Compared with normal P supply, rice grain yield and shoot P accumulation decreased and P utilization efficiency increased under low P supply. Correlation analysis showed that rice grain yield positively correlated with P utilization efficiency, shoot P accumulation of both growth early stage and growth mid-stage (p0.05)under low P supply ,while rice grain yield was positively correlated with P utilization efficiency and shoot P accumulation of growth early stage (p0.05)under normal P supply.Therefore, screening and breeding rice genotypes with higher P utilization efficiency and higher ability to accumulate P at the early stage of grouth would probably be one of the alternatives to alleviate the P deficiency of paddy soil in south of China.
