ЭВГАЛОФИТТІ АҚСОРАНЫҢ (SUAEDA SALSA PALL.) ТАМЫР ЖҮЙЕСІНІҢ БЕЛСЕНДІЛІГІНЕ NACL-ДЫҢ ƏСЕРІ

Abstract

For the purpose of study the relationship between the characteristics of the root system, activity and saline pressure of Aksora (Suaeda salsa Pall.) various concentrations of NaCl (0, 200, 400 and 600 mmol/L) were prepared. The effect of salt concentration on the biomass of Aksora (Suaeda salsa Pall.) root and the activity of the root system was studied. The results showed that as the NaCl concentration increased, the dry and fresh weight of the Aksora (Suaeda salsa Pall.) roots, the total length and surface area of the root increased and then gradually decreased. The highest values of dry weight, fresh weight and total length of the vascular system were observed at a concentration of 200 mmol / L NaCl, while at a concentration of 600 mmol/L NaCl, the dry weight, wet weight and total root length, and surface area signifi cantly decreased. These results indicate that refi nement of Aksora with higher concentrations of NaCl salt can increase the total length and absorption area of roots, thereby promoting root growth and adaptability to saline pressure. However, it has been found that with extrmely high salt concentrations inhibit root growth by reducing the total root length and absorption area. Key words: Aksora, vascular activity, NaCl, absorption zone.
