The paper analyzes the elements of the stand structure and proposes silvicultural measures to improve conditions in the stand of black locust (Robinia pseudoacacia L.) and common hackberry (Celtis occidentalis L.) aged 28 years in Subotica-Horgoš sands. The research was performed on three permanent experimental plots on which selective thinning (T1...

Growth and structure of Italian alder ( Alnus cordata /Loisel/ Duby) trees were analyzed in a linear plantation established by planting two-year-old seedlings at Fruška 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...

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 t...

A morphometric analysis was conducted on three-year-old Turkey oak seedlings naturally regenerated from 2015 mast year in a degraded stand at Fruška gora on the site of pedunculate oak, European hornbeam and Turkey oak with limes (Carpino betuli-Quercetum roboris (Anić 59) Rauš 1971 var. geograf. Tilia argentea + Tilia cordata B. Jovanović & Tomić...

The paper presents the growth characteristics of one-year-old seedlings of three autochthonous oak species (Fagaceae family): Turkey oak (Quercus cerris L.), Hungarian oak (Quercus frainetto Ten.) and downy oak (Quercus pubescens Willd.) in suboptimal growing conditions. The analyzed oak species are widely distributed in Serbia. One of the most imp...

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 i...

Istraživanje je provedeno u kulturi alohtone vrste Gymnocladusdioicus (L.) K. Koch na Fruškoj gori, osnovanoj 1932. godine s razmakom sadnje 3 × 3 m, na staništu lužnjaka i običnog graba ( Carpino betuli - Quercetum roboris /Anić 59/ Rauš 1971. ), na nadmorskoj visini 120 m. Elementi rasta stabala i sastojine u dobi od 75, 80 i 85 godina ukazuju na...

This paper presents the structure of well-preserved, mature stands of seed origin and young stands that followed either after planned regeneration or spontaneously in the understory reinitiation stage, in monodominant sessile oak forests (Quercetum petraeae Cer. et Jov. 1953.) from two subassociations, tilietosum and typicum, in the territory of ?D...

The genus Gymnocladus (Fabaceae) consists of five species with reproductive system described as polygamous, monoecious and dioecious. The species Gymnocladus dioicus (L.) K. Koch has been present in Serbia for over 150 years. Its flower sexuality was described as dioecious, but there are references stating that there are flowers that are morphologi...

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 paper studies the effects of two heavy selection thinnings on the increment of Norway spruce trees exposed to ice and snow breaks in eastern Serbia. In a thinning that was carried out at 32 years of age, 556 candidates per hectare were selected for tending, and at the age of 40, of the initial candidates, 311 trees per hectare (55.9%) were sele...

Abstract: The paper presents the occurrence of subspontaneous dispersal of Kentucky coffeetree in the park-forest which is a part of a protected natural area ‘’Topčiderski park’’ in Belgrade. In 1949, three trees of Kentucky coffeetree not older than 85 years were recorded. In 2016, one sexually reproductive tree was recorded in Topčider which is a...

In this nursery experiment, 100 one-year-old northern red oak seedlings were measured at the end of the 2016 growing season. Measured growth elements were: total height, root collar diameter and total leaf area. All seedlings were classified according to the presence of polycyclism into four types: one-flush growth, two-flush growth, three-flush gr...
