Фітотоксичний вплив SO2, NO2 та іонів свинцю на вегетативні органи декоративних рослин
Phytotoxic effect of SO2, NO2 and lead ions on the vegetative organs of decorative plants

Summary/Abstract: Influence of acid gases and lead ions on the vegetative organs of decorative plants has been studied in a model experiment. The morphometric indices of stem and assimilative apparatus are considered. Changes of the plants height and assimilating area are described. The damage of plants’ sprouts was found. The phytotoxic effect of SO2, NO2 and lead ions on the growth and development of the above-ground organs was determined. The Tagetes patula L. is a resistant to the action of acid gases and lead ions. Calendula officinalis L., Salvia splendens L. and Chrysanthemum leucanthemum L. were determined to be most sensitive to the influence of by SO2, NO2 and Pb2+ respectively.
