Abstract:
The effects of drought stress on some saxual‘s (Haloxylon aphyllum) morphologicalcharacteristics was studied by weight and drainage lysimeters from 1380 to 1384 in yazdShahid-Sadughy desertification research station. The moisture treatments included pot capacity (control), one-third pot capacity and drought that carried out in randomize complete block design (RCBD) with three replicate. After the control of soil moisture, the moisture treatments were irrigated, on the other hand after seedling establishment in drought treatment irrigation was stopped. The moisture treatments were carried out in two growth season and its effects on morphological characteristic such as height, crown diameter, canopy cover volume, leaf length, number of ties in leaf length unit and canopy cover weight was studied. The results showed that the amount of soil moisture were not significant on height, canopy cover volume and number of ties in leaf length unit, but it had significant effects on crown diameter (p=0.030), leaf length (p=0.010) and canopy cover weight (p=0.004).
