Chromium Stress Tolerance of a C4 ( L.) and C3 ( L.) Plants Primed with UV and Gamma-Treated .

Chromium stress is one of the deleterious abiotic factors that reduce crop production. Two anatomically different crops (C3 and C4) were compared for their chromium (0 and 50 ppm) tolerance and responses towards (). Strains of were exposed to UV (30-210 min) and gamma irradiation (1-4 KGy), and the best mutants were selected on petri plates containing selective markers.
