Abstract

In order to survey of the effect of osmohydropriming on germination and growth of cotton plantlet under drought stress, two experiments were carried out at emergence and plantlet stages. In the first experiment, cotton seeds were primed with distilled water (hydropriming) and Poly Eltylene Glychol 6000 (-2, -4, -6, -8 bar) (osmopriming) and controlled seeds were subjected to 5 levels of osmotic potential (0, -2, -4, -6, -8 bar). The experiment was conducted as a factorial experiment based on completely randomized design. The second experminent were conducted with control and pretretmented seeds (hydroprimed) and osmoperimed seeds using Ploy Ethylene Glycol at three osmotic levels -2, -4 and -6 bar under three levels of drought stress 30, 60 and 90 percentage of field capacity (FC) using two-liter pots at Agricultural and Natural Resource Research Station of Kashmar. The results of experiment test showed, hydropriming of cotton seed had the most growth percentage and rate as well as dry weight of seedlings in all treatments (except -4 bar) in comparison with control. The results of pots experiment indicated, osmo and hydropriming of cotton-seed increased growth (plantlet height), leaf area, dry weight of shoot and root significantly in compaison with control. Drought stress at 30 and 60 percent of (FC) treatments decreased leaf area and plantlet height.
