    Opis:
    The research issue focuses on potential interception, which is the maximum amount of water that can be stored on plant surface. Tests under controlled conditions remain the best way to enhance knowledge on interception determinants in forest communities. Such tests can provide data for identification of mathematical models based on ecological criteria. The study presented in this paper concerned tree interception under simulated rain in a range from 2 to 11 mm/h. To perform the experiment a set of sprinklers was designed and built. The study included two deciduous species: beech (Fagus sylvatica L.) and oak (Quercus robur L.). Descriptive characteristic and nonlinear estimation were suggested for the obtained data. Interdependence of potential interception, the intensity of rain and the size of raindrops were described using exponential equation. The intensity and drop size of simulated rainfall significantly influence the obtained values of potential interception. Data analysis shows a decrease of interception value with an increase of intensity of simulated rainfall for both analysed species. Every run of the experiment that differed in the intensity and size of raindrops reached an individual level of potential interception and time needed to realize it. The formation of ability of plants to intercept water depends both on the dynamics and the time of spraying.

    Opis:
    The subject of this research was the interception of precipitation, which is defined as the amount of water that can be retained by the entire surface of a tree. The aim was to measure the rate of interception under laboratory conditions in order to determine influential factors. To eliminate water absorption that would occur in living trees, we employed models of deciduous and coniferous trees enabling us to examine the effect of precipitation characteristics and the surface area individually. A sprinkler system that automatically recorded the amounts of water retained on the models was set up in the laboratory. Precipitation was simulated using 5 different intensities with 3 different raindrop sizes. Interception rates were affected by both, the intensity of the precipitation and raindrop size. The time required to reach maximum crown filling with water was variable and depended on plant surface parameters as well as simulated precipitation. The maximum water capacity of crowns was not a constant value even within one tree model, but changed depending on precipitation characteristics.

    Opis:
    The subject of the study is the process of interception by plants defined as the process of retaining rainfall water on plant surface, counting retention by individual plant parts or the vegetation cover as the whole. In the quantitative approach, interception capability of plants may be compared to a reservoir, the capacity of which is determined mostly by the surface of plants. Among many approaches to describe interception processes, a lot of attention has been focused on research concerning the forest vegetation with reference to atmosphere – forest stand – soil balance. Hence, in the present paper interception issues are addressed in view of forest ecosystems. The emphasis is also put on the methods and results of studies carried out under laboratory conditions. Up-to-date literature on interception is abundant. The authors tackling this issue regularly define their own variable and complex sets of terms. This paper is an attempt to review and organize knowledge presented in existing literature on the subject.

    Opis:
    Quantity approach of forest trees interception necessary for build mathematical formulas need to be measured in continuously controlled conditions. We developed original methodology and build all equipment for measure interception in laboratory, which allows to achieve comparable results. It was also experimentally found to what extent the prepared apparatus allows for the assumed variability of selected parameters of simulated rainfall.

    Opis:
    The concept of potential interception is used to determine maximum amount of water that can be retained by the surface of all parts of a sprayed tree. The word ‘potential' is supposed to emphasize the fact that ‘maximum interception' is not a constant value. For each individual rainfall it may assume a different value. Potential interception values depend each time on rainfall intensity and drop size. Nevertheless, formulas describing the influence of species specifics of trees and other characteristics of surface are still being searched for. It is also being indicated that some characteristics may demonstrate a certain dynamics related to time of exposure to factors capable of modulating these characteristics.
