AB  - In this paper, a change of diameter structure in a pre-maturing stand of black locust and common hackberry under the influence of a late thinning is analysed. The research is based on three permanent experimental plots and two measurements of diameters in a five-year period. One of the plots is a control plot and two plots are experimental, where the thinning was carried out in a stand 28-years old, with the thinning intensity of 28.9-30.6% of the initial density, approximately evenly distributed across diameter classes. In the investigated stand common hackberry came from the neighbouring areas in the stand structure. The initial measurement in the autumn of 2014 confirmed the share of common hackberry of 16-18% in the total number of trees thicker than 5 cm with a dominantly reversed J shape of the diameter structure and the presence of trees in all the diameter classes. In the period of stand age from 28 to 33 years, a dominant process on all treatments was the mortality of thinner trees, while the recruitment of common hackberry trees was recorded in all treatments. On the control plot, a quarter of the trees died, while an eighth of the remaining trees died in the thinned plots, mostly black locust trees. In thinned plots, only black locust trees died with a characteristic that the intensity of mortality was higher in thinner trees, while in the control plot some thick black locust trees died, as well as and some thinner common hackberry trees. In the five-year period, numerical parameters of variability (standard deviation, coefficient of variation), the shape of distributions (skewness and kurtosis) and heterogeneity of diameters at breast height (Gini index, Lorenz asymmetry coefficient) have shown a trend of increasing variability and change of diameter distributions of trees in all treatments, but it is more expressed in thinned plots compared to the control plots. Growth dominance coefficient of diameters shows that the competition between the collectives of both species and the black locust collective is of asymmetric type and more expressed in the thinning treatments. In common hackberry trees on the control plot the competition between the trees is of asymmetric type, while on the thinned plots, the competition is of symmetric type. This shows that after thinning, common hackberry has a biological potential that is higher than that of black locust and that the natural succession can be accelerated through thinnings.

AB  - Growth and structure of Italian alder (Alnus cordata /Loisel/ Duby) trees were analyzed Us a linear plantation established by planting two-year-old seedlings at Fruska Gora (Serbia). The aim of this paper is to point out the growth characteristics and the structure of the Italian alder linear plantation at age 11 and 16 years and contribute to the knowledge of adaptive and productive potential of the species in the available plantation in Serbia. The spacing between the trees was 7 m (200 trees per hectare). The plantation is located on anthropogenically changed pedun cul ate oak and hornbeam site at 125 m above sea level. On the basis of 35 measured trees at age 11 and 16 years, the top height was 15 and 21 m, and the Lorey's mean height 13.4 and 19.5 m. The dominant diameter was 32.4 cm at age 11 and 59.4 cm at age 16 years. The mean quadratic diameter was 25.1 and 47 cm.The productivity of the plantation is high. At age 11 years, the basal area was 9.9 m(2).ha(-1), and the standing volume 107.2 m(3).ha(-1)while at age 16 years, it was 34.7 m(2).ha(-1) and 305.1 m(3).ha(-1), respectively. In the period from 11 to 16 years of age, the periodic annual increment in diameter was 4.4 cm.year(-1), height 1.22 m.year(-1), and in basal area and volume 4.9 m(2).ha(-1).year(-1) and 39.6 m(3).ha(-1).year(-1), respectively, pointing to fast growth of Italian alder. Despite the limits due to a small sample and the fact that the linear plantation was analyzed, we generalise the following conclusion: the measured growth characteristics at age 11 and 16 years of Italian alder trees show that the species can grow fast and could be usable in similar areas.

AB  - In silviculture, the characteristics of growth of seedlings in relation to light conditions are an important indicator of the success of natural regeneration. The paper shows the growth characteristics of one-year-old Hungarian oak seedlings in full light conditions in a field experiment conducted in 2016 in the nursery of the Faculty of Forestry in Belgrade. Four hundred seedlings were analyzed and classified according to the number of shoot growth flushes into three growth types: one-flush growth, two-flush growth and three-flush growth type. Within the analyzed four hundred seedlings, 39.8% belonged to the one-flush growth type, 58.2% to the two-flush growth type, and only 2.0% of the seedlings to the three-flush growth type. The one-flush growth seedlings have less leaves and lower values of height, root collar diameter and total leaf area, but they are characterized by a higher mean height of the primary axis (the height of the first growth flush), compared to the multi-flush growth seedlings. This is pointing out to different growth characteristics in the initial stage of development and during the growing season between different types of seedlings.

AB  - 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).

AB  - The paper studies effects of two heavy thinnings on the increment and slenderness of various categories of trees and stability of the stand as a whole. The research was conducted on a permanent experimental plot in an Norway spruce (Picea abies /L./ Karst.) monoculture in Serbia. This monoculture was established with 5,000 seedlings per hectare on the site of mountain beech forest and the effects of heavy thinnings were investigated in the 33-40 and 41-50 age periods. To determine the thinning effects we compared current diameter increments (i(dt)) and current height increments (i(ht)) of dominant trees (D-100 and D-400) obtained by a detailed analysis of trees and of mean stand dominant trees (D-100 and D-400). At the stand level, we compared the current diameter (i(d)), basal area (I-G) and volume (I-v) increments of all trees and of the same collective of aspirants in two periods after the thinnings, between the ages of 33 and 40, and between the ages of 41 and 50. The first thinning was carried out at the age of 32 when the dominant trees were 15 m tall and the next at the age of 40 when the dominant trees were above 20 in in height. They were both low (q(d)  lt  0.85) and heavy selective thinnings (34-36% of the volume). A more significant increase in the diameter increment was recorded after the second thinning between the ages of 41 and 50. It amounted to 29.1% in aspirants and 36-42% in dominant trees (D-100 and D-400) compared to the period after the first thinning, i.e., between the ages of 33 and 40. The thinnings further contributed to the establishment of more favorable relations in diameter and height increments of the trees in the studied culture and thus improved their stability.
