Abstract
DK961 is a salt tolerance wheat cultivar which had been approbated by Shandong authority organization,and its salt tolerance had been proved favorable by field production.But the salt tolerance mechanism of it is still not clear.In this study,the salt tolerance mechanisms of DK961 was studied with SN215953 as control under salt stress condition(200 mmol/L NaCl) simulated artificially in the laboratory.The experiments was carried out from two aspects: the seedlings growth and the photosynthetic organizations.The results indicated that,under salt stress,the salt-tolerance cultivar DK961 could maintain better growing state than SN215953,such as higher biomass(fresh weight and dry weight) and relative water content,and its seedlings were significantly higher than SN215953.All those could dilute the concentration of salt absorbed by root from the salinity environment in order to protect the cytoplasm.At the same time,salt stress notably decreased Hill reaction activity and Ca~(2+)-ATPase activity of the leaves in two wheat cultivars,but the restriction to DK961 was much less than SN215953.This superiority ensured DK961 to maintain the stability of photosynthesis.So the two aspects above may be important for DK961 to endure high salt concentration.
