Abstract

Hymenocrater yazdianus is endemic of Yazd province, Iran. A completely randomized design with six replications was used to investigate the effects of drought stress on some morphological and physiological characteristics of the plant. The results showed that the soil moisture content has a significant effect on the properties of canopy and root size, leaf thickness, average of leaf area, root to shoot ratio, chlorophyll (a, b and total), proline and soluble sugar. The minimum and maximum values of the canopy, leaf area, root volume and weight, was related to the field capacity of 25 and 75 percent, respectively, and the highest amount of root to shoot ratio with an average of 1.86 was related to the field capacity of 100%. Relating to the physiological factors, the lowest and the highest amounts of a, b and total chlorophyll as well as proline were related to the field capacity of 100% and 25%, respectively. In the case of water soluble sugars, no significant differences were observed between treatments. Drought stress had no significant impact on the characteristics such as plant height, shoot dry weight, relative water content (RWC) and water saturation deficit (WSD). The overall results of this study suggest that Hymenocrater yazdianus by utilizing some defense mechanisms such as reducing the size of the canopy, leaf area, volume and weight of the roots and increasing the thickness of leaves, the amount of chlorophyll and proline would be compatible with dry conditions.
