Abstract

Atriplex leucoclada Boiss is one of the most important native species of dry and semi-arid rangelands in Iran which is faced to low germination and seed dormancy. In order to investigate the effective methods of breaking dormancy of this species, an experiment was conducted in a completely randomized design with eight treatments including scarification treatments 100 and 200, hypochlorite: at 5, 10, 15, 20, 25 minutes, boiling water treatment: submerging seeds in boiling water for 1, 5, 10, 15, 20, 25 minutes, wet chilling : putting Seeds in a refrigerator at 4 ° C and continuously wet at intervals of 1, 2, 3, 4, 5, 6, 7, 8 weeks, Sulfuric acid treatment: Seeds in Sulfuric Acid 98% Diets: 5 seconds, 30 seconds, 5, 10, 15, 20, 30 minutes, Seeds Dry chilling: in a refrigerator at 4 ° C at intervals of 1, 2, 3, 4, 5, 6, 7, 8 weeks, and Seed burial treatments were carried out in four replications in two laboratory sections (petri-dish cultivation) and cultivation was done in a pot. In the laboratory section, no significant results were obtained, but in the culture, results of data analysis indicated that 25 min hypochlorite treatment had the highest rate of germination and 100 mg treatment and hypochlorite treatment of 25 minutes had the best effect on seed dormancy.
