The Effect of Salt Concentration on the Germination of Soybeans

Abstract

In order to solve the problem of crop growth difficulty in saline-alkali soil, it is meaningful to discuss how much salt affects the growth and germination of soybean. Zhonghuang 35 with low salt tolerance and Zheng 1311 with high salt tolerance were selected respectively, and NaCl solutions with concentrations of 0.250, 0.250, 0.125, 0.0625 and 0 mol L-1 were set for hydroponics, the effect of NaCl concentration on soybean germination was determined by variance analysis. The results showed that the concentration of NaCl was significantly correlated with the germination rate of Zhonghuang 35 and Zheng 1311 soybean varieties. The health of soybean is inversely proportional to NaCl concentration. The effect of NaCl concentration on germination in Zhonghuang 35 was more obvious than that in Zheng 1311. This study provides a theoretical basis for soybean growth in saline-alkali soil.
