Abstract

This objective is to provide a basis for chosen of fire resistant tree species in the southern area of China. Physiological indexes of drought-resistance，namely the four water parameters of osmotic potential at the turgor loss point（p），water potential at the water saturation point （0），bulk modulus of elasticity （），and the rate of bound water in cells（Vp /V0），for the three fire resistant trees，Schima superba，Cyclobalanopsis glauca，and Elaeocarpus glabripetalus，were studied using the pressure-volume（P-V） technique. Averages of the four water parameters for the three species in three growing seasons（March-May，July-August，and October-November in 2008） were then compared. Results showed that （1） in different seasons，water parameters of S. superba and C. glauca had similar trends and ranges but were different from E. glabripetalus. Also，（2） drought resistance from averages of the water parameters was C. glauca ＞ S. superba ＞ E. glabripetalus.［Ch，2 fig. 1 tab. 11 ref.］
