Title
Effect of seed priming on seed germination behavior of Plantago ovata plant under Salt Stres
Authors
Abstract
Abstract
In order to investigate the effect of seed priming on germination characteristics of Plantago ovata under salinity stress condition, an experiment was conducted in Ramin Agriculture and Natural Resources University, Khuzestan, The experiment was arranged in Randomized Complete Block Design) with 4 replications. Treatment consisted of 6 levels of seed priming (primed with distilled water, potassium nitrate, gibberellic acid (GA), salicylic acid, salts Nacl and without prime) and salinity levels (no stress, 135 mM and 270 mM salt). Results showed that salinity reduces rate and percentage of germination. Non-stress conditions, primed seeds with GA only after 6/68 hours to reach 50% of final germination. Non-stress conditions, the highest and lowest germination percentage achieved of primed with GA and salicylic acid. In mild stress conditions prim with potassium nitrate and in severe stress prime with GA led to highest percentage and final germination reached 50% earlier. So in salinity stress primed with potassium nitrate and GA can increase seed germination rate and percentage of Plantago ovate plant.
