Abstract
A sand culture experiment with a split design was conducted to study the responses of seedlings of five Camellia oleifera clones under three levels of P stress( P0( 0 mmol/L),P1( 0. 05 mmol/L),P2( 0. 5 mmol/L)). The results showed that five clones were significantly different in tolerance to low phosphorus stress. With low P stress exacerbating, the biomass and the N and P absorption of tested clones decreased,whereas the nutrient utilization efficiency increased. In low P and P deficiency treatments,the biomass and the P absorption and utilization efficiency of Xianglin67 and Xianglin69 were higher. Leaf( N / P) and leaf Δ( N / P) ratio were lower. There were better phosphorus nutrient recycling mechanism in Xianglin67 and Xianglin69. Those clones could be considered to be excellent low P stress resistant clones.
