Malondialdehyde content in the leaves of small-leaved linden tilia cordata and Norway maple acer platanoides under the influence of volatile organic compounds

Abstract

Malondialdehyde (MDA) content is a widely used parameter as a measure of lipid peroxidation in plant tissue that increases under oxidative stress. In model experiments, the effect of various doses of volatile organic compounds (o-xylene, benzopyrene, butyl acetate) on the MDA content in the leaves of small-leaved linden Tilia cordata Mill. and Norway maple Acer platanoides L. was studied. It was found that one day after the treatment butyl acetate has the strongest stimulating effect on the MDA content in the leaves of small-leaved linden and o-xylene and benzopyrene - in the leaves of Norway maple. Three days after processing, o-xylene and benzopyrene are highly active substances for small-leaved linden, and benzopyrene for Norway maple. The complex effect on the leaves of small-leaved linden and Norway maple seedlings with a mixture of butyl acetate and o-xylene leads to an increase in the toxicity of butyl acetate in the presence of o-xylene compared with its single effect. Under natural conditions, the MDA content in the leaves of small-leaved linden and Norway maple near industrial factories was 1.5-2.0 times higher than in the plants growing in protected areas. Ontogenetic and species differences in the MDA content in the leaves of small-leaved linden and Norway maple caused by their growth in different industrial zones were established.
