Interspecific variations of bark´s water storage capacity of chosen types of trees and the dependance on occurance of epiphytic mosses

Abstract

Many studies show that the rates of water storage capacity can differ between different types of trees. The main purpose of this study was to compare specific water capacity of chosen types of woody species (Acer pseudoplatanus, Betula pendula, Carpinus betulus, Malus sp. as the representatives of broadleaved trees and as the representatives of coniferous were chosen species Larix decidua, Picea abies, Pinus sylvestris). In some cases the rates of water retention capacity between the chosen trees were considerable, e.g. the water retention capacity of Malus sp with the tree trunk perimeter of 100 cm was 0,886 g/cm3 and water storage capacity of pendula with a tree trunk perimeter of 100 cm was 0,342 g/cm3. There were big differences between the losses of moisture during a 24-hour period. The understanding of differences in interspecific variation of water retention capacity can help us to gain a better insight into occurrence of some organisms living on tree trunks and their dependence.
