"Presented study contributes to knowledge on the role of aminoaldehyde dehydrogenase as an enzyme participating on aminoaldehyde oxidation as a partof polyamine catabolism in plants, in the mechanisms of dedence reaction during salinity stres. we observed the highest increase in biomass producition a concurrent decrease in AMADH activity in pea seedlings cultivated in Na+ : K+ ration 1:2 in total salt concetration 40mM. We confirmed the postitive role of Ca2+ ions in media of 60mM NaCl or KCl on biomass production accompanied by decrease in AMADH activity. AMADH may participate in salinity stress defense mechanism by production of -alanine, which can further metabolised to important cellular osmoprotectant -alaninbetaine. Another importnat metabolite is GABA which participates in cellular processes like cytosolic pH regulatnio, antioxidative defence and intercellular signalling."@en .
