The thesis "Evaluation of Physiological Quality of Tree Planting Stock" deals with four testing methods to evaluate the physiological quality of planting stock and verifies their objectivity and usefulness for application in the natural conditions in the terrain at planting Norway spruce and European beech. These checked methods are: measuring of figures out percentage of water losses caused by a constant thermic stress, comparing weight before and after water saturation of close root balls, measuring of root balls humidity and measuring of chlorophyll fluorescence. The first three methods seem to be perspective and should by further testing and observations. The measuring of chlorophyll fluorescence cannot be used for water loss examination before planting. The development of available methods for determining physiological quality of tree planting stock is important for the success of planting in poor weather conditions.
