EFFECT OF AMBIENT ENVIRONMENT FACTORS ON THE CHEMICAL COMPOSITION CHANGES IN LEAF PLATELETS OF BIOINDICATIVE HYDROPHYTIC PLANTS AFTER THE EXAMPLE OF DEEP GREEN HORNWORT (CERATOPHYLLUM DEMERSUM L. )
A study is made of the influence of ambient environment factors on the chemical composition and anatomic constitution of the foliage of bioindicator hydrophytic plants (deep green hornwort) making use of the Fourier transform IR spectroscopy, scanning electron microscopy and X-ray microanalysis (XMA) methods. A correlation is established between the occurrence of intensity changes and position of absorption bands in the IR spectra of the plant samples and anthropogenic pollution of the places of their inhabitation. Deformation of epidermis cells in the plant leaf samples taken from the polluted places. The results of the study of chemical composition of hornwort tissues are presented. Heavy metals were detected in the samples taken from the polluted places. The above-listed reactions observed under the condition of polluted environment should be regarded as protective-adaptive mechanisms of the cells. This fact is indicative of high accumulative and adaptive properties of aquatic plants.
