Relationship between the Salt Tolerance and H2O2 Accumulation in the Root of Wheat Seedlings
小麦根系过氧化氢积累与耐盐性的关系

The two 93029 # and 906 # wheat varieties have different abilities of salt tolerance, the former has much lower salt tolerance ability than the latter. The results indicated that the membrane permeability, the MDA content and the H 2O 2 level increased; but the activity of POD decreased in the root cells of 93029 # variety seedling under salt stress, in contrast, the four traits have no obvious change in 906 # variety. These results suggest that the salt tolerance ability is directly related to the accumulation of H 2O 2 in wheat seedlings roots.
