Variation of Nutritive Element Contents in Fruit of Chinese Bayberry (Myrica rubra) During Development

In this study, the variation of N, P, K, Ca, Mg, Fe and Se contents in Ruansianhaibian'Chinese bayberry flesh and stone were determined and analyzed dynamically during fruit development.The results showed that the contents of N, P, K, Ca, Mg and Fe in flesh and stone were decreased gradually during the development of fruit maturity, and the average contents of various elements were higher in flesh than in stone.The order on the content ratio of flesh to stone was P< Mg<N<Se<Fe<K<Ca.In different development stages, the coefficient of variation in the content of N, P, K, Ca, Mg Fe and Se for flesh and stone were from 18.74% to 68.19% and 25.45%to 69.59%, respectively.
