Abstract
Cover plants application has several advantages such as beauty in landscape, inhibition of soil erosion and the best way of using water. Frankenia (Frankenia Leavise) is one of the valuable cover plants in the environment. According to water deficit, estimation of water requirement can reduce the irrigation volume and human power. Drought is an important inhibiting factor in plants which affects growth and development. This research was conducted to study the effects of regulated irrigation (100, 70 and 50% field capacity) on Frankenia under a randomized complete blocks design in boxes (50*70cm) with three replications. After 60 days of drought treatment, chlorophyll concentration, proline, electrolyte leakage, fresh and dry weight of roots and shoots were measured. The results indicated that chlorophyll concentration significantly decreased by declining soil moisture in field capacity (F.C.), while proline contant and electrolyte leakage increased. There was no significant difference in fresh and dry weight of shoots and roots between 100 (control) and 70% treatments.
