Abstract

The growth and photosynthetic characteristics of Phoebe bournei pot seedlings applied with 0, 50, 100, 150, 200, 300, 400, and 600 mg nitrogen per seedling in a greenhouse were investigated. The 100 mg·seedling-1 level could accelerate the mean height, ground diameter and leaf area growth; the biomass of most organs was the highest for seedling applied with nitrogen at 150 mg per seedling; the ratio of root to shoot decreased with the increasing of nitrogen fertilization; the photosynthetic performance and growth index of P. bournei seedling was consistent, the content of chlorophyll a, chlorophyll b and total chlorophyll increased then decreased with the nitrogen fertilization increased; the net photosynthetic rate, stomatal conductance, intercellular CO2 concentration and transpiration rate were observed to increase with the increase of nitrogen from 0 to 100 mg per seedling and decrease with further increase of nitrogen fertilization from 100 to 400 mg per seedling. Statistical analysis indicated that the photosynthetic gas exchange parameters and transpiration rate varied significantly under different nitrogen treatments. So it is concluded that 100-200 mg nitrogen per seedling is the appropriate range for seedlings of P. bournei nursed in a greenhouse.
