Growth elements of the trees and the stand of gymnocladus dioicus (l.) K. Koch at Fruska Gora (Serbia)

Abstract

The species Gymnocladus dioicus (L.) K. Koch has been present in the territory of Serbia for over 150 years, and is most commonly cultivated in the form of decorative single trees or in small groups. The largest heterogeneous group of trees is situated at Frugka Gora on the site of pedunculate oak and hornbeam. The growth elements of trees and the group (stand) are presented in this paper. The spacing between the trees in the stand was 3 x 3 m. The growth elements of the trees and the stand are shown for 75, 80 and 85 years of culture ages, for all trees and collectives of trees that were developed under the influence of different growing space. The productivity of the stand is high. At the age of 85 years, 502 trees per hectare were determined with quadratic mean diameter (d(g)) of 39.6 cm, dominant diameter (D-100) 51.5 cm, Lorey's mean height (h(L)) 33.0 m, dominant height (H-100) 35.0 m, basal area 61.74 m(2).ha(-1) and volume of 918.23 m(3).ha(-1).
