Study of the Influence of Lead Microelement on the Process of Water Accumulation in (Phaseolus vulgaris) Plants

Abstract

In this study our goal was to analysis the influence of different concentrations of lead on the process of water accumulation in the roots and stems of bean seedlings. In the experiments, the Borlotti variety are used. The seeds (100) were soaked in the corresponding lead acetate solutions: V1 – distilled water; V2 - 0.001%; V3 – 0.005%; V4 – 0.01% and V5 – 0.1%. and were put in germinators. The roots and stems of 10 seedlings of each experimental variant were used for determining the quantity of humid and dried substance. The control had high quantity of humid substance, which proves that the water contained in the vegetal material was important for the growth of these organs. The most significant decrease was recorded at concentrations above 0.1%, being highly inhibited.
