Abstract: 【Objective】 To study the growth characteristics，physiological and biochemical characteristics of the precious tree species under the Phyllostachys edulis forests，and provide theoretical reference for the interplantation of the precious tree species and construction of the mixed forest under the Ph. edulis forests. 【Method】 The Ph. edulis forests with continuous concentration and consistent site conditions were selected. 1 800 bamboo plants·hm^-2 were retained，the same specifications of three precious tree species such as Ormosia hosiei，Phoebe chekiangensis and Cinnamomum japonicum were selected for interplantation，with a planting density of 300 trees·hm^-2. After planting for about 2 years，the growth data，leaf photosynthesis parameters，chlorophyll content，soluble sugar content，soluble protein content，malondialdehyde content and antioxidant system activity under different treatments were analyzed. 【Result】 Among the three tree species，the growth (ground diameter and seedling height) from high to low were C. japonicum，O. hosiei and P. chekiangensis. The Pn，Gs，Ci and Tr of O. hosiei were higher than those of the other two species. The contents of chlorophyll a，b，a+b in leaves and the concentration of carotenoid quality from high to low were O. hosiei，P. chekiangensis and C. japonicum. The activities of POD and CAT in O. hosiei were significantly higher than those in P. chekiangensis and C. japonicum，but no significant difference in SOD activity was observed. MDA of P. chekiangensis was significantly higher than that of O. hosiei and C. japonicum，and the contents of soluble protein and soluble sugar in C. japonicum were the highest. 【Conclusion】 O. hosiei has good ecological adaptability to the environment of the Ph. edulis forests and is an excellent precious tree species suitable for interplantation under the Ph. edulis forests.
