Abstract:
Exogenous Put treatment (10-2 mM) showed a valuable results on germination and growth of bean (Phaseolus vulgaris L. cv. Giza 6) under normal and NaCl-induced stress. Germination percentage of Put treated seeds increased to 88% under salinity stress, may be due to the activation of amylase and protease enzymes during germination. The rise of K+/Na+ ratio in shoots of Put treated seedlings under NaCl-induced stress suggest that Put treatment may partially ameliorate the adverse effects of sodium and chloride ions. Put treatment improved growth of salt-stressed seedlings, may be through the partial inhibition of amylase and protease enzymes and increasing the total content of nucleic acids and photosynthetic pigments. Changes in protein banding patterns suggest that a defense-response genes could be activated by Put treatment.
