Opis:
This paper presents the genetic variability in the growth parameters and morphological traits, as well as the silvicultural quality of progeny of 23 European beech (Fagus sylvatica L.) provenances from south−eastern Poland. The research was conducted on the experimental plot established in the Łosie Forest District in spring 2006. After 10 years, during the spring and autumn, we determined and measured the spring phenology and survival rate, the diameter at breast height (dbh), the tree height, and the straightness of trunk. The results obtained point out the considerable variability of analysed features, both within and between different beech populations (tab.). Highest and lowest survival rates are noted for the beeches from Lutowiska and Leżajsk (populations 451 and 461), respectively (fig. 2). Lowest mean height and dbh were achieved by beeches from Bircza (453), while the tallest and broadest trees were from the Kielce population (390) (fig. 3−4). The overall silvicultural assessment based on survival, height, dbh, spring phenological phases and straightness of the trunk revealed that the most valuable populations of beech are those originating from Kielce (390), Bircza (454), Strzyżów (459), Lesko (452), Rymanów (457) and Lutowiska (451). In turn, the analysis resulted in least favourable assessments for beeches from Bircza (453) and Gromnik (362). Thus, we confirmed also that trees of local origin are not always best−adapted to (and do not always grow best in) the place they originate from. The obtained results are highly relevant from the principles of creating the seed source regions for beech in Poland, as the proper selection of a population for the given place of growth may yield benefits for forest ecology and management.

Opis:
The paper contains results of the study concerning infestation of cones of fir Abies alba Mill. by insects. They were represented by conophages: Barbara herrichiana Obr. (Lepidoptera: Tortricidae), Dioryctria abietella (Fabr.) (Lepidoptera: Pyralidae) and Earomyia impossibile Morge (Diptera: Lonchaeidae), and seminiphages: Megastigmus suspectus Borr. (Hymenoptera: Torymidae) and Resseliella piceae Seitn. (Diptera: Cecidomyiidae). The cones were collected in the Forest District Łosie (the Kraków Forest Region) in 1999, 2000 and 2003.

Opis:
European beech is one of the most important broadleaved tree species in Poland and will play probably even more significant role in the future due to the predicted climate change. The main objectives of this study was to analyse and compare the growth parameters and morphological traits between 23 European beech provenances from south−eastern Poland (fig. 1). The research was conducted on the experimental plot established in Łosie Forest District in 2006. The experiment employed a randomized complete block design consisting of 92 plots (23 provenances×4 blocks). On each plot 100 trees representing given provenance were planted in 1.5×1.5 m spacing. In the spring and autumn 2015 we measured and determined the following parameters for the subsample of 36 trees on each plot: survival rate, tree height, diameter at breast height, diameter of the branch at the middle height of the crown length, stem straightness, crown shape, tendency to create forks, mean angle between stem and branches and spring phenology. We also included different eco−physiographical characteristics for each provenances (tab. 1). We performed basic statistics to describe mean values and standard errors (fig. 2, tab. 2) and finally we quantified the interaction between traits and eco−physiographical characteristics by Principal Component Analysis (PCA) (fig 3, tab. 3). The obtained results indicates that under growth conditions on experimental trial in Łosie Forest District, the provenances from lower elevated regions with lower precipitation and higher mean temperature (i.e. more arid conditions; Kielce and Narol provenances) were characterized by thicker dbh and branch dimeters in contrast to regions from southern Poland (Łosie, Bricza 1, Stary Sącz and Nawojowa). European beech provenances from regions with more humid conditions and lower mean annual temperature, as well as shorter vegetation season are characterized by higher survival rate. They are also higher than other provenances, but reveal the lower ratio dbh to branch diameter.

Opis:
Research was carried out in 13 fir stands representing a spectrum of typical Carpathian selection forests. In most of them, no selection cutting was applied except for Krynica I and II stands. The stand volume oscillated between 384 m3/ha and nearly 628 m3/ha. The maximum dbh age of the stands ranged from 100−120 to over 200 years. Dbh distributions attained the form of a J−shaped curve with the highest number of trees in the smallest diameter class, however, none of these curves showed conformance with Liocourt−Meyer's theoretical distribution. From the analysis of the undergrowth, it can be concluded that three stands showed unsatisfactory amount of undergrowth. In general, the intensity of cuts in the majority of sites was high. This is related to the specifics of these stands which, in most cases, have not yet been managed under the selection system.
