Comparative Study of Plant Drought with Account Taken of Biochemical Mobility of Heavy Metals

Resumo

The impact of water deficit in the soil on the growth of Armenian semi-tooth-shaped sweet corn under various soil and climatic conditions was assessed. The plant drought response was studied by kinematic growth profiles with account taken of contrast sensitivity to stress factors depending on the soil and climatic conditions, as well as of background concentrations of some heavy metals. The drought effect is reflected in changes of the physiological growth parameters of the fifth leaf of corn. The plant drought tolerance was assessed at the seedling stage by measuring the total length of the plant and accumulation coefficients of heavy metals.
