The effect of volatile organic compounds on the content of photosynthetic pigments in reed fescue leaves Festuca arundinacea Schreb. in experiment terms (for example, limit, aromatic hydrocarbons and esters)
The article presents the results of the photosynthetic pigments content analysis (chlorophyll a, b and carotenoids) in the leaves of one of the most common representatives of the urban herbaceous plants — reed fescue Festuca arundinacea Schreb., in controlled experimental conditions. The content of pigments in the leaves in one day after treatment with organic compounds sharply decreases compared to three days occurred after treatment with pentane, hexane, benzene, as well as mixtures of pentane and hexane; pentane and hexane with benz(a)pyrene. The influence of o-xylol, benz(a)pyrene, butyl atetate; mixtures of butyl acetate with o-xylol and benzene with o-xylol caused a more intense reduction in the content of pigments three days after the treatment of plants. At the same time, the maximum change in the content of pigments during the experiment is caused by the action of butyl acetate, o-xylol and a mixture of butyl acetate with o-xylol; and the greatest decrease in the content of pigments compared to the control was observed under the action of o-xylol.
