Description
| - Vertical leaf distribution and relative irradiance were ascertained for the dominant species Ulmus laevis Pall. at the level of the individual tree and at the level of the stand in a mixed broad-leaved forest in South Moravia, the Czech Republic. The study consisted of detailed, destructive measurement of 5 selected sample trees and the establishment of basic biometric parameters for the entire stand. Using allometric relationships, measurements from sample trees were generalized to DBH (diameter at breast height) classes and were then scaled up to the level of the imaginary pure stand of elm; the selected independent variables were tree height and DBH. The vertical leaf distribution was unimodal in trees with smaller dimensions and bimodal in trees with larger dimensions. The leaf area index (LAI) of the stand was 4 (6.4 including the undergrowth), and the sunlit leaf area index (SLAI) was 1.7. Dominant trees had a higher proportion of sunlit leaf area than subdominant and suppressed trees. Determination of appropriate methods and intensity of thinning can lead to optimizing of irradiation control, vitality increase of the elm stands and subsequently to a higher resistance to Dutch elm disease vector and disease itself.
