The effects of salinity stress at the levels of 50, 100, 200, 400, 800, 1600, 3200 mg.L-1 of NaCl on morphological indexes,physiological indexes such as invertase expression and carbohydrate metabolism in tomato (cv. Zhongza No. 9) seedlings were studied under hydroponic culture. One purpose of the study was to find the condign salinity stress .The results were showed as follows.
Plant height and relative plant height were increased, stem thickness and index of seedling growth were ...
