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...

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 effect of NaCl salt stress on chlorophyll fluorescence-related parameters, such as the maximum quantum yield of primary PSII photochemistry (F<inf>v</inf>/F<inf>m</inf>) and the performance index for energy conservation from photon absorbed by PSII antenna (PI<inf>ABS</inf>).

In somaclonal lines, F<inf>v</inf>/F<inf>m</inf>, PI<inf>ABS</inf>, MDA and LT showed coefficients of variation of 13.7, 39.3, 25.5, and 3 %, respectively, for La Candelaria and 1.4, 17.6, 34.4 and 3 % for Yerua.

On other hand, the MDA content showed a strong negative correlation with the PI<inf>ABS</inf> content in somaclones of both rice cultivars, suggesting that MDA levels could also be used as an oxidative damage index in rice somaclones. © 2015, Franciszek Górski Institute of Plant Physiology, Polish Academy of Sciences, Kraków.
