ABSTRACT

Cultivation of barley and oat in the limiting areas of tailings pond might be regarded as one of the possibilities that could lead to the general amelioration of these places. In order to characterize the waste products, to determine and evaluate the components that may be levigated from waste products and that can affect the limiting areas of tailings pond, levigation tests were performed.

In this paper, we have observed the influence of eluate, obtained from levigation tests, on seed germination, radicle and coleoptyle development as well as on the amount of accumulated dry matter for Avena sativa L. and Hordeum vulgare L., genotypes.

According to our researches, we may conclude that the studied genotypes of Hordeum vulgare L. and Avena sativa L. showed tolerance to eluate while values registered for seed germination, radicle and coleoptyle development as well as dry matter content were comparatively higher than those registered for the control variant.
