THE CHANGE IN ECOLOGICAL, ANATOMICAL AND ANTIMICROBIOLOGICAL PROPERTIES OF THE MEDICINAL PLANT TILIA RUBRA DC. SUBSP CAUCASICA (RUPR.) V. ENGLER ALONG AN ELEVATIONAL GRADIENT

Abstract

In this study, ecological, anatomical and antimicrobial properties of Tilia rubra DC. subsp. caucasica (Rupr.) V. Engler which has several medicinal characters were investigated. There were significant differences both seasonal period and localities, in terms of N, P concentrations. There were no significant differences with respect to soil factors expect P2O5 concentration of the studied localities. The leaf length and width was decrease with altitudinal increases. Anatomically, cuticle, leaf thicknesses and the number of epidermal cells increase with in altitude. The results of the antibacterial and antifungal screening of extracts the flower and leaf of T. rubra subsp. caucasica from different district were investigated by diffusion disc plates on agar and the agar dilution method. It was observed that the extracts of flower and leaf have antimicrobial activity.
