Comparative Study Of Stress-Adaptive Physiological Alterations In Plants Caused By The Action Of Heavy Metals Under Chloride Salinity Conditions

The qualitative distinctions in adaptive physiological biochemical response reactions of pumpkin plants to
heavy metals of different nature under salinity conditions were shown on the example of dynamics of
growth, accumulation of various forms of nitrogen and activities of proteolytic enzymes. It was confirmed
that plant responses to combined action of toxicants depend on species of plants and their belonging to
concrete ecological groups. Data showed the low species-specific tolerance of Cucurbita pepo L. belonging
to glycophites, to copper and its noticeable resistance to lead and nickel under conditions of salinity.
