Abstract

Abstract: The seedlings of plum leaf crab and SH were used as test materials. The salt tolerance of plum leaf crab and SH seedlings were compared by different salt concentration treatments. The results showed that the changes of chlorophyll content of the two rootstocks showed the opposite trend at low salt concentration, but the same trend at high salt concentration. The trend of chlorophyll content of the two rootstocks decreased first and then increased,and the rising trend of Plum leaf crab is greater than that of SH. At high salt concentration, the free proline content of the two rootstocks was accumulated, while the soluble protein content decreased, the soluble sugar content in the leaves of Plum leaf crab showed an upward trend, and the soluble sugar content in the leaves of SH showed a downward trend. The change trend of SOD activity in plum leaf crab was ascending-descending-ascending-descending, POD activity was ascending first and then descending, and the activities of two protective enzymes in SH blade interior showed an upward-downward-upward trend.
