Abstract

In order to develop “water saving garden” and provide a theoretical basis to the green of arid areas. The experiment was conducted with 5 species tree seedlings of evergreen broad-leaved （Prunus zippeliana，Lithocarpus glaber，Cinnamomum camphora，Schima superba，and Photinia glabra × P. fraseri ‘Red Robin’） under different soil drought stresses such as stop watering for 0 day，5 days，10 days，15 days，20 days，30 days and 35 days in pots in order to compare their drought resistant ability. Characteristics and physiological indicators of five tree species were studied with different drought stresses. Results showed that when soil water content for the five evergreen tree species decreased，the leaf relative water deficit increased，the water loss rate decreased，cell membrane permeation increased，and proline content increased. Also the range of different tree species and stress times were not the same. Through comprehensive analysis of these indexes of 5 seedlings，it was concluded that the drought resistant ability of these 5 species decreased in order： C. camphora＜S. superba＜L. glaber＜Photinia glabra × Photinia fraseri‘Red Robin’＜Prunus zippeliana.［Ch，1 fig. 5 tab. 21 ref.］
