Abstract

In many studies, the medicinal properties and impact of plantago ovata on mechanisms of human physical activities has been proven. So that one of the most useful, effective and harmless herbal laxative. drought is one of the limiting factors and a serious danger for the successful production of crops. An experiment was conducted to study germination characteristics of plantago ovata under water and drought stress conditions at different temperatures. The experiment was conducted at the University of Tehran lab, Karaj, in 2015. Temperatures regimes included 5, 10, 15, 20, 25, 30, and 35 °C). For each temperature, the treatment for drought and water stress was four potentials (zero, -4, -8 and -12 bar) with sodium chloride. The effects of drouth stress on seed germination of plantago ovata at different temperatures showed the highest resistance to drought at 20 º C. drouth stress at different temperatures reduced germination parameters nad in the potential -12 germination stopped. Increased temperatures resulted in better conditions for seed germination and increase the drought stress tolerance. Increased severity of drought causes the reduction of temperature range in which the seed can germinate.
