Abstract:
Taking cucumber seedlings with different salt resistance of‘Jinchun 2’and‘Jinyou 3’as materials,the physiological indexes and growth were studied under different concentrations of continued salt stress.The results showed that the plant height,root length,biomass accumulation,ratio of root to shoot,the contents of chlorophyll and soluble protein were lower than those in contrast,and decreased with the increased of NaCl concentration.While the soluble sugar content was first rose and then declined,and the relative conductivity were increased under continued salt stress treated.The effects of ‘Jinyou 3’ which had higher salt tolerance index and salt-tolerance ratio was lower than‘Jinchun 2’under same salt stress contents and time.
