چکیده | ||
Astragalus squarrosus Bunge is one of the native and compatible range species in the dry lands of Iran. It is great importance in terms of tolerance to specific ecological conditions as well as high nutritional value and soil conservation. In order to study the effects of seed priming on some morph-physiological traits, an experiment was conducted as split plots based on a randomized complete block design with five replications in Torud Research Farm in Semnan Province, Iran in 2017. Seed samples collected from their natural habitats in Yazd, Kashan and Semnan in Iran. Seed of three A. squarrosus ecotypes were treated by hydropriming (distilled water), hormonal priming (gibberellic acid: with concentrations of 125 and 250 ppm), (Salicylic acid: 100 and 200 mg/l) and (Ascorbic acid: 100 and 200 mM), osmopriming (potassium nitrate: 0.3 and 0.2%) and control. The primed seeds and controls were sown in the field. No seeds were germinated for control and gibberellic acid (250 ppm). The results showed that the effect of priming was significant on leaf carbohydrate content, vegetation cover, dry matter (DM) yield and plant height (p | ||
