So one ofthe obstacles to the development of plants that is salinity and drought during seed germination. in thisstudy we evaluated the effects of salinity stress on Helichrysum globiferom and Helichrysum aucherigermination properties based on a In the form of a factorial experimental design with four replicationsand four salinity levels (0-50-100-150 mM sodium chloride) in seed Ecology laboratory of Sari NaturalResource Faculty. Seeds of two species were collected of Qushchy pastures in 70 kilometers of the old roadof Urmia-Karabakh. Results showed that salinity stress had a significant reducer effect on percentage andspeed of germination, growth of root and shoot length in two Species. Amount of reduction in the total inall traits species of Helichrysum globiferom species of Helichrysum aucheri. The amount of this reductionin all traits in Helichrysum globiferom was less than Helichrysum aucheri species. The ratio of Root toshoot length (allometric coefficient) also was the highest in Helichrysum globiferom. So we conclude thatthis species is more resistant than other species. So the highest decrease in both species was observed ingermination percentage, germination speed, and root, shoot and plant length, in treatment 150 mM.}, keywords = {Salinity stress,germination,Saline lands,Helichrysum}, title_fa = {مطالعه بررسی گونه های Helichrysum􀀃globiferum و Helichrysum aucheri بر احیای اراضی شور حوزه های آبخیز}, abstract_fa = {}, keywords_fa = {تنش شوری,جوانه زنی,اراضی شور,Helichrysum}, url = {https://www.wmji.ir/article_699910.html}, eprint = {https://www.wmji.ir/article_699910_e03d7c6d8ebcd638b3d7c6b5c5ca5320.pdf} }
