Abstract:In higher salt tolerant plants adaptation to saline conditions is associated with osmotic adjustments leading to the accumulation of low molecular weight solutes. This thesis mainly treats with the capacity of salt tolerant plants from Yuncheng saltlake to accumulate soluble solutes. Yuncheng saltlake (350°E, 110°N) located in the south of Shanxi Province and at the foot of Zhongtiao Mountains. With the elevation of 320m, the mean annual precipitation of 600mm and evaporation of 1734mm. Serious salinized s...
