Effect of salt stress on photosynthetic pigments, proline and MDA content of PGPR-inoculated wheat plants.
Chlorophyll a, Chlorophyll b, carotenoid, proline and MDA content was measured in leaves of 60 d old wheat plants grown in soil supplemented with 150 mM NaCl and inoculated with STR1. Control: non-inoculated wheat plants, PGPR: plants inoculated with Dietzia natronolimnaea STR1. Values are mean of five replicates ± standard error of means. Different letters indicate statistically significant differences between treatments (Duncan’s multiple range test P < 0.05).
