Purslane (Portulaca oleracea L.) is one of the valuable medical plants. Drought also is one of the most important environment stresses that influences metabolism and growth of plant. The studying of physiological plant response rather than water stress can be influential equipment for understanding drought resistance mechanisms. In this study, the drought stress effects on germination and physiological characteristic of the medical plant (purslane) were studied. Drought imposed on polyethylene glycol (PEG) seedlings and experiments were done in completely random model framework, with 3 replications. Polyethylene glycol stress was in seven levels involving blank (distilled water), -0.1, -0.2, -0.4, -0.6, -0.8 and -1 MPa. In relation to germination, meaningful difference was not observed between blank and the different levels (P |
