Abstract: To understand variability in different plus tree seedlings of Phoebe bournei, seeds from 11 plus trees from Zhenghe, Fujian Province were compared to 13 plus trees from Jianou, Fujian Province for growth indices, photosynthetic rate, and transpiration rate of one-to two-year-old seedlings in a container seedling experiment. Results showed strong differences in height, ground diameter, biomass, photosynthesis, and transpiration among the progeny. Two-year-old seedlings were greater than one-year-old seedlings with average height of 56.4 compared to 29.3 cm [coefficient of variation (cv) of 27.6%], average ground diameter of 4.91 compared to 3.50 cm (cv of 14.8%), and average biomass variation of 27.965 compared to 5.985 g (cv of 37.6%). Two-year-old families compared to one-year-old had an average net photosynthetic rate of 5.122 compared to 2.081 molm-2s-1 (cv of 6.1%), average transpiration rate of 1.829 compared to 0.715 mmolm-2s-1 (cv of 21.9%), average water utilization efficiency of 12.31% compared to 4.36% (cv of 19.7%), and average light energy utilization efficiency of 3.703 compared to 2.224 mmolmol-1 (cv of 13.8%). The family seedling of No. 8 plus tree(J8) from Jianou, Fujian had the best growth performance in height, round diameter, biomass, net photosynthetic rate, water utilization efficiency, and light energy utilization efficiency. So the growth and physiology characteristics of plus trees from Jianou, Fujian were superior to Zhenghe, Fujian. Based on a selection rate of 20%, five plus trees(J8, J1, J13, J12, and J4) were chosen.[Ch, 6 tab. 23 ref.]
