Abstract: The nutrient content of leaves and roots of Camellia oleifera grafted seeding was studied under different water conditions in order to provide a basis for reasonable fertilization and improve resistance of Camellia oleifera seedling. The content of C, N and P content of biennial Camellia oleifera grafted seeding under different water (soil moisture content: 28%-31%, 15%-18%, 9%-12%) and nutrient (0, 0.375, 0.75 g per seedling) conditions was investigated by physiological and biochemical tests. Results showed that low nitrogen (0.375 g per seedling) application made for C, N, P and K accumulation under soil water stress condition. Low and high nitrogen application made for C, N and P accumulation, but had no effect on K accumulation under light water stress. Low nitrogen application prompted C, N, P and K accumulation of leaves as well as C, N and K accumulation of roots under severe degree soil water stress. However, high nitrogen application could not prompt C accumulation of leaves but prompted C and N accumulation of roots instead.
