Bioindicating Importance of Chlorophyll Fluorescence for Some Woody-Shrubby Plants in Winter
R. O. Sobchak, Yu. S. Grigoriev
Abstract
The state of winter dormancy and release for some evergreens, semi- and deciduous woody and shrubby plants growing under the natural and anthropogenic conditions in the Republic of Altay were investigated by means of recording fast and delayed fluorescence of chlorophyll. It was shown that the degree of winter dormancy, the rate of release and stability to thermal stress are the informative indices for early diagnostics of the injury of plants with industry-related emissions and biological indication of the level of environmental pollution in the region. It was noted that the brown colour of the leaves of Daurian rhododendron in winter has the adaptive importance.
