Abstract

We experientially studied the influence of exometabolites of pond frog Rana ridimunda on the growth of roots and springs of barley Hordeum vulgare. The grains of barley we raised by using different solutions of exometabolites: from 0.01 up to 100 %: running water was used as a control. We have found out that metabolites of hibernating pond frogs in the state of winter hibernation inhibit the growth of barley’s seeds, decreasing its germanating, development of toot system and spring growth. On the contrary, metabolites from frogs being kept under increased temperature and daytime stimulate seeds’ growth. There are no direct correlation between exometabolite concentration and influence on the barney germination: the most simulative effect on the root development has exometabolite/water 1:10 000 solution.

Keywords
