Wych elm
Opis:: Vegetative progeny were obtained from 46 elms (Ulmus glabra Huds.) by grafting. These grafted trees were planted in 2009 in a clone archive in forest plot 264j in the Bielsk Forest District. After one year of growth, elm clone survival ranged from 38% to 100% (89% on average). Although all clones were of similar age and were grown under similar conditions, their average height was highly variable and ranged from 99.0 cm (clone no. 9473z) to 186.6 cm (clone no. 9645z), while average root collar diameter ranged from 8.4mm (clone no. 9473z) to 18.0 mm (clone no. 9645z). There were large differences crown architectural among the different clones, and variation in average shape of the crown was high (from 2.6 in clone no. 9655 to 3.8 in clone no. 9446z). Index breeding values determined on the standardized data for height, root collar diameter, crown shape and survival, ranged from -0.71 (clone no. 9473z) to 0.61 (clone no. 9645z). Clones from Czerwony Dwór reached a better breeding value (0.17) than clones from Gołdap (-0.0266), and variation in their average breeding values was high (0.197).

Opis:: The aim of this work was to investigate the variability of different features in wych elm Ulmus glabra Huds. populations growing in the conservative plantation in the Kolonia Forest Subdistrict (Oleszyce Forest District). We examined the survival rate, height, and spring flushing of the elm trees as well as the occurrence of two leaf morphotypes after ten years since the establishment of the plantation. Statistically significant differences were found between the studied populations in terms of survival and height growth, while no difference was observed for spring flushing, which may be due to the close proximity in which the tested populations grow. The highest rate of survival was observed in the Bircza 33a population (87.3%), whereas the Lutowiska 40b population grew tallest (344.3 cm). Elms with leaves typical of the U. glabra ssp. montana (morphotype A – 84%) dominated the stand, while elms with leaves characteristic for the U. glabra ssp. glabra (morphotype B) were a minority with only 4%. However, within the Lutowiska 137g population, the share of morphotype B was as high as 25%
