Abstract

The present study aimed to perform biochemical
studies to search possible indicators for differentiation in the
early development stages of rice varieties, in relation to their
degree of tolerance to saline stress. Leaf samples of two
varieties with different degrees of tolerance to salinity (Pokkali
and Amistad-82) and grew up in greenhouses growing in
nutrient solutions simulating the salt stress (8 and 12 dS.m-1),
were analyzed. At 35 days after planting, it was assessed the
activity of the enzyme peroxidase, total protein content, proline
and lipid peroxidation. The results showed a differential
behavior of the varieties in their degree of tolerance when
using the EC 12 dS.m-1 which allows using the activity of the
enzyme peroxidase, proline concentration and lipid peroxidation
in the discrimination of rice genotypes tolerant to salinity.
