اثر غلظت مختلف كلرور آلومينيوم بر برخي پارامترهاي فيزيولوژيكي گياه لوبيا ( Phaseolus vulgaris L)

The effects of different concentrartions of aluminium chloride (A1C13) on certain physiological parameters in bean (Phaseolus vlgaris L.) plant

The effects of A1C13 with different concentrations of 0, 50, 150, 300, 450, 600, and 750 mM on certain physiological parameters in bean plants {Phaseolus vulgaris L.) during 25 days growth period (15 days Treatment) in hydroponic cultivation environment were studied. With increasing aluminium chloride, carbohydrate and protein contents were increased. In high concentrations of A1C13, peroxidase activity increased, however, in 50 and 150 mM A1C13 in comparison with control, peroxidase activity decreased and also with increasing aluminium chloride, catalase activity increased in comparison with control, but in 600 and 750 mM A1C13 catalase activity decreased.
