Abstract

This test by strong salt resistance of cucumber varieties of spring at 39, tianjin, tianjin research 4 as the experimental material, studied the different concentrations (0.0%, 0.3%, 0.6%) NaCl treatment on the influence of different cucumber seedling growth and physiological indicators. In cucumber seedling growth to two leaves one to salt stress, five times after processing, the determination of different concentration of the survival rate of different varieties of cucumber seedlings under salt stress, such as plant height, stem diameter growth index and malondialdehyde content, soluble protein content and other physiological indicators. By analyzing the growth index data, found that in 0.3% NaCl concentration when spring 39 and tianjin, tianjin research 4 cucumber seedling growth situation, the best is superior to contrast and 0.6% NaCl concentration, through the analysis of physiological index data, find spring 39, tianjin, tianjin research 4 cucumber seedlings of soluble protein content, malondialdehyde content, plasma membrane permeability increased with the increase of NaCl concentration; The root activity decreased with the increase of NaCl concentration. Can be seen from the data, 0.3% NaCl treatment have less effect on cucumber seedling growth and physiological indexes, 0.6% NaCl treatment of cucumber seedling growth and physiological index affected by salt stress significantly, including tianjin research than 4 jin chun 39 significantly.
