Abstract:

The measurement of the seasonal and diurnal variations of Tamarix ramosissima and Populus euphratica water potentials in the southern fringe of Taklamakan Desert indicated that there was no apparent water stress for the two species during their growth period,with little change of predawn water potential and some extent decrease of midday water potential.Irrigation once or thinning had no significant effects on the water status of the plants,while groundwater appeared to be a prerequisite for the survival and growth of these species.It is very important to ensure a stable groundwater table for the restoration of Tamarix ramosissima and Populus euphratica in this area.
