Woody plants as bioindicators of air pollution level

This paper considers the quantitative evaluation of atmospheric pollution on the basis of impact on the winter dormancy of woody plants. To estimate the depth of winter dormancy has been used method of recording curves of thermally induced changes in the zero level of fluorescence (TICZLF) in chlorophyll-containing tissues. The proposed method can be used to compare the sensitivity of species of woody plants to anthropogenic impacts, and zoning by the level of pollution.
