Abstract

Saltbush (ATRIPLEX LEUCOCLADA) is one of the endemic halophyte plants of Iran, useful for desertification, restoring and modifying rangelands in arid and desert areas cultivation. To assess the effects of mechanical and chemical treatments in break SEED DORMANCY and to stimulate seed germination in dimorph seeds of ATRIPLEX LEUCOCLADA, two tests were performed in completely randomized design with three replicates for both of its two seed types. Treatments were: scratch pre-treatment, gibberellic acid or kinetin, ethephon, potassium nitrate or thiourea all performed for 24 h or 48 h at 4°C or 20°C, pre-treatment running water, moist chilling (20 days/4°C) +14-days treatment with gibberellic acid or potassium nitrate or thiourea, scratching with a sand paper, making a gap with a needle, hot water (70°C or 90°C for 15 min), sulphoric acid (75%), drystoring (3 months/20°C), stratification (3 months/4°C). As the twice-scratched pretreatment caused the highest germination percentage (73.3%) and vigour index (8860) in the brown seeds and for the black ones these values were 63.3% and 7710, respectively. Overall, it is concluded the SEED DORMANCY in both types of seeds in A. leucocladacould be physical.
