Summary:

The object of the research is interception container which is created by the surface of pine. Surface of trees is the greatest extent varies the potential intercep-tion altitude - the maximum possible amount of water that a tree can catch after a single rain.For precise ibterception studies in the lablratory conditions only to determinate the LAI coefficient was not enough. The aim of study was to determinate interception surface of tree based on digitized images of needles and branches using SigmaScan 5.0 Pro. Two methods were used to obtain images of needles - using scanner and a camera. The results and proposed methodology of measurement allowed to calculate the interception container of a single tree.
