چکیده انگلیسی
Selenium, which is an essential microelement for animals, positively affects growth and development of some plants by enhancing the activities of antioxidant enzyme. The study was conducted in order to determine the effects of selenium (0, 4, 8 and 16â¯mgâ¯Lâ1) on salt stress (0, 30, 60 and 90â¯mM NaCl) subjected garlic plants grown in hydroponics. According to results, salinity reduced chlorophyll index and carotenoid contents. Se application 8â¯mg Lâ1 in 30â¯mM NaCl salinity and 4â¯mgâ¯Lâ1 in 60â¯mM NaCl salinity significantly improved chlorophyll index and carotenoid contents, RWC was increased by application of 16â¯mgâ¯Lâ1 Se under 90â¯mM NaCl, in garlic leaves. Also, with further increases in Se to the medium containing 30â¯mM NaCl, K concentration gradually increased in leaves. Analysis of Na content in leaves revealed that Na concentration increases with increasing salinity. Moreover, it is concluded that Se increase in K uptake and decrease in Na uptake under salt stress.
