Research Abstract

The viability of root-tip cells under salinity stress is closely related with the sodium accumulation in shoot of rice. Not only the activity of antioxidants (Ascorbate peroxidase and catalase) but also the activity of cyanide-resistant alternative respiration may relate to decrease the amount of the reactive oxygen species in roots and cell death. This suggests that these activities in roots are important to improve the salinity tolerance in rice.
