| Abstract: | The leaves of mango ( Manglfera indica L. ) of seedlings were treated with
different water stress for our studying on the mechanism of cell injury. The results
showed that the relative water content and water potential decreased with the increase in
water stress. The rate of superoxides free radical generation increased with the increase
in water stress. The water stress strength was in direst proportion to the amount of O
generation. The trend of change in MDA contents was similar to that in O generation
rate. It can be concluded that the cell damage of leaves in water stress is caused by
membrane lipid peroxidation first, meanwhile, increase in MDA content, and cytoplasmic system destruction. |
