Makhrova Y. The visual changes of forest species according to imitation of factors of global ecological crisis in microcosms

In the thesis the methodological basis the use of microcosms for diagnosing the visual changes of forest species, includes a specially developed research's methods of concern to be addressed in the course of their use, was elaborated. The technology was tested on the example of self-seeding of forest-forming species of Chernivtsi region. The complex of sensitive test-signs to these factors was revealed and the integral index for assessing the resistance of seedlings of different species was offered. The importance of the sign of the integral index of asymmetry of leaves, which set the offset asymmetry from right to left was proved. More resistant to acid rain and high temperatures was self-seeding Abies alba Mill, and the least resistant - Quercus robur L.
