LIGNIN LOCALIZATION AND CONTENT IN PHRAGMITES AUSTRALIS IS SENSITIVE TO CHANGE IN WATER BALANCE ENVIRONMENT

*O. M. Nedukha

ABSTRACT

The sensitive of lignin localization and its content in leaves of Phragmites australis to change in the water balance of soil was established by using the cytochemical method, laser confocal microscopy, scanning electron microscopy and biochemical method. We investigated leaves of young plants Ph. australis (stage of vegetative growth), which used as a source of vitamins and to treat colds in medicine. The results were received by the comparison of the data in leaves of Ph. australis of the water-aquatic and terrestrial plants grown in nature. It was found that the decrease in soil moisture leads to an increase in the content of lignin in the epidermis and tissues of the conductive bundles of leaves of terrestrial plants. We assume that the increased of lignin content in the epidermis of leaves of terrestrial plants indicates that the leaves of both air-water and terrestrial plants of the reed can be used as a source of lignin for medical purposes.
