Effect of different salts on the seed germination of halophyte Aksora (Suaeda Salsa Pall.)

Abstract

The stress effects of a solution of salts and soil extract on the seeds of euhalophyte Aksora (Suaeda salsa Pall.) were studied. Treatment of euhalophyteSuaeda salsa Pall. seeds of salts (Na2SO4 and NaCl) and soil extract solutions in different concentrations (0; 0.6; 1.2; 1.8; 2.8; 3.6 g / 100 ml).Monitoring of the relationship between salts (Na2SO4 and NaCl) and soil extract solutions of grown Aksora seedlings after treatment. Additionally, provide the description of the germination of seedlings grown at different concentrations of solutions of different salts and soil extracts. Determination of endurance of seeds to different concentrations of Na2SO4 and NaCl salts and soil extract solution, based on the germination of Axora seeds. Study of the endurance of Axora seeds to salt stress. The experimental results showed that the growth rate of Aksora seedlings in different salts (Na2SO 4 and NaCl) and soil extracts is expected to be different. Based on the germination rate of seeds and Aksora seeds respond differently to stresses of different concentrations of Na2SO4 and NaCl salts and soil solution, the stress effect of Aksora seeds can be expressed by the following relationship NaCl> soil extract> Na2SO4. Due to the endurance of Aksora to salt stress, it was found that it is very prone to saline and saline soils. Key words:Saline soils, halophytes, Aksora (Suaeda).
