| Abstract: | This paper studied the absorption and distribution of phosphate in potato by using 32P. Results showed that potato assimilating 32P content increased as growth period, which it was significantly positive correlation, and the 32P fertilizer of potato assimilation distributed great amount in stem, secondarily in root and leaf. The percentage of stem assimilation 32P at the total part increased as growth period progressed, but the percentage of leaf reduced, the root was not changed. |
