Abstract: Under the changed watering condition of progressive soil water stress-rewater，the betaine content and the betaine aldehyde dehydrogenase (BADH) activity were the highest while the tissue relative water content (RWC) of winter wheat seedling was in the range of 80%to 70%. The betaine content and the
