Atmospheric pollution bioindication with the fluorescent method use

The atmospheric pollution level quantitative assessment possibilities on the basis of the impact on thewood plants winter dormancycondition are considered in the article. To assess the winter dormancy depth, the curves registration method for thermo-induced changes of zero level fluorescence (ТИНУФ) in chlorophyll containing tissues was used. This phenomenon can be used as the atmosphere pollution informative bio-indicatingfactor around the industrial enterprises and in the urban environment.
