THE INFLUENCE OF FOREST DENSITY INDEX AND ALTITUDE ON SELECTED FEATURES OF THE BILBERRY (VACCINIUM MYRTILLUS L.) BASE IN MOUNTAIN STANDS
Anna Barszcz, Mariusz Karpierz
ABSTRACT
The research was conducted in the lower forest zone, in Stary Sącz Forest District. It concerned the variability of features of the bilberry base in groups of stands which differed as to their forest density index and altitude. The research proved a modifying influence of the growth conditions of bilberry on its fructification, features of fruit and the height of dwarf shrubs. It confirmed statistically the significance of differences in the intensity of fructification, weight and diameter of berries depending on forest density index (including open areas). Altitude had a significant effect only on fructification.
Key words: bilberry, site, altitude, fructification, features of fruit, height of dwarf shrubs.
