Chlorophyll fluorescence and lipid peroxidation changes in rice somaclonal lines subjected to salt stress
The aim of the present work was to explore physiological changes provoked by somaclonal variation in response to salinity. Two parental cultivars (La Candelaria and Yerua) and their derived somaclones were used as a source for breeding new rice lines with improved salt tolerance. We studied the effe...
