Abstract
Climate conditions in cities are constantly changing, creating a worsening environment for the growth of trees and performing their ecological functions. Qualitative evaluation of their responses to the often extreme climatic conditions and habitat for their growth is an important part of care for urban and historical greenery. This work deals with applying visual methods for the assessment of morphological characters, crown destructive manifestations and eco-physiological aspects of vitality through micromarker of quality of assimilation organs. Evaluation was carried out in two types of environment, in city of Nitra and an environmentally unloaded historical park in Nová Ves nad Žitavou. The research was conducted on six trees of species Acer pseudoplatanus L., through visual assessment and measuring the values of chlorophyll fluorescence-a. The measurement results were statistically evaluated and graphically interpreted.
Keywords: trees in city, evaluation, visual markers, chlorophyll fluorescence
