Abstract


The articles presents the results of assessment of the cadmium ions impact on fluctuating asymmetry of measuring and metrical parameters of cucumber seedlings leaves. The measuring parameter was the amount of left and right third order nerves, directed to the right and left from the second order nerve of a true leaf which connects the footstalk and the top of the leaf. The metrical parameter was the area of the left and right halves of a true leaf and the length of cotyledonous leaves. The plants grown in soil containing 5 acceptable concentrations of cadmium (10 mg Cd/kg) the fluctuating asymmetry of measuring parameter significantly exceeded the same parameter of control plants fluctuating asymmetry. The influence of cadmium on the measuring parameters of cotyledonous and true cucumber leaves was not found.

Key words


fluctuating asymmetry, cucumber seedlings, cadmium
