Na+ and K+ accumulation at Atriplex grains (Halimus, Nummularia, Canescence) after application of NaCl at the germination stage

Abstract

This study is based on showing the extent to accumulation of the Na+ and K+ As a way to tolerate high grades of salinity Which is characterized by the plant Atriplex. This experiment was applied to the laboratories of the faculty of science of nature and life at the Echahid Hamma Lakhdar University of Eloued during the year 2016-2017, To understand the behavior of the three kinds of seeds of Atriplex (halimus, canescens, nummularia), at the application of different doses of (Na Cl) which: (0 g/L, 1 g/l, 2 g/l, 4 g/l, and 8 g/l). Up to the germination stability make the analysis of salt accumulated (Na+ and K+) at the grain level of each dose applied by spectrometer a flamm. This experiment was done according to a random design in three repetition, the results showed the dominance of variety of A. halimus with respect to A. nummularia. and A. canescens at germination level and . The results also showed the dominance of A. halimus versus A. nummularia and A. canescens at the level of adaptation for high concentrations. Also the results have generally shown that the A. nummularia 5150 (mg/l) has a strong storage with respect to A. canescens 4800 (mg/l) and A. halimus 3250 (mg/l)  at both low and high Na+ concentrations, for K+ concentration the strong storage in A. nummularia 173(mg/l) with respect to A. canescens158 (mg/l) and A. halimus 132 (mg/l) . According to the results it can be deduced that the grains of A. halimus was the most potent for salt stress before the variety A. nummularia following them, while the Atriplex. Canescens was too sensitive, and the concentration (0 g/l) is the perfect concentration and suitable for all.
