The studies were carried out in 1994-1997. The experimental bushes were grown in Puławy. Eight cultivars were examined (,Ben Alder', ,Ben Lomond', ,Ben Nevis', ,Ben Tirran',,Ceres', ,Ojebyn',, Titania',, Triton'). Pollen grains viability was estimated in acetocarmine slides, while germination ability was estimated on agar medium. All cultivars showed high viability (80-100%). Weather conditions (especially temperatures at the time of blooming) had significant influence on germination ability. In colder years, only 10-40% of pollen produced pollen tubes, while in warmer years 50-80%. The biological value of blackcurrant pollen grains can be more effectively estimated on the basis of their ability to form pollen tubes than their viability.

In 2004-2006, an experiment was established at the Experimental Station Rajkowo belonging to the Agricultural University (West Pomeranian University of Technology) in Szczecin. High blueberry bushes were planted in an alkaline reaction (pH 7.1) heavy soil using three different substrates. The bushes were planted in trenches filled with peat, cocoa husk and sawdust. The fertilization of the plants was limited to a sole nitrogen supply (30 kg N ha-1), because chemical analyses of both the soil and the substrates showed high and/or moderate content of other nutrients. In order to decrease cocoa husk reaction and to maintain the reaction of peat and sawdust, the bushes were irrigated with H2SO4 acidified water up to pH 2.5-3.5. The bed prepared of cocoa husk was characterized by the highest N (23.8 mg 100 g-1), Zn content (51.6 mg kg-1), and pH (5.0). On the other hand, sawdust substrate had the lowest salinity (0.35 g NaCl kg-1). Sawdust substrate showed the highest level of Mn (56.5 mg kg-1) and Cu (7.4 mg kg-1) and the lowest of Ca (83 mg 100 g-1), whereas, peat substrate showed the highest salinity (0.87 g NaCl kg-1) and the lowest pH (3.8). The usage of cocoa husk substrate resulted in the highest content of N (23.6), K (6.9 g kg-1) and Mn (104.5 mg kg-1) in cv. Sierra blueberry leaves as well as N (16.0) and K (6.5 g kg-1) in berries. The plants grown in sawdust substrate showed the highest level of Ca (1.75 g kg-1), Cu (3.2) and Zn (12.4 mg kg-1), in the leaves as well as S (1.7) and Cu (3.5 mg kg-1) in berries.

The studies refer to the phenomenon of hyperparasitism in the municipal environment. The paper presents the occurrence of fungi of the genus Ampelomyces on Erysiphales – important group of phytopathogenic fungi. For the first time in Poland analyzed degree of infestation of Erysiphales mycelium by Ampelomyces and effect of the hyperparsites on the degree of infestation plants by Erysiphales. The high participation of the Ampelomyces was noted in each year of the study. Substantial differences were noted in the occurrence of Ampelomyces depending on the developmental stage of the host fungi and considerable differences in the prevalence of the hyperparasites on particular Erysiphales species. In all cases examined, the mean index of infestation of host plants by Erysiphales was higher than the mean degree of infestation of powdery mildew mycelium by Ampelomyces. The results indicate that under natural conditions they do not play any significant role in the reduction of the degree of infestation of host plants by Erysiphales and do not disturb drastically their life cycle.

The experiment of the additional blow of bushes of 8 cultivars of blackcurrant (Ribes nigrum L.) was conducted in 1995–1997 in Pulawy, Poland. The artificial wind blow generated by the vacuum cleaner fan was used. The additional blow of free-pollinated and isolated bushes did not caused better pollination of flowers and did not have any positive effect on the weight of 100 fruits, the yield structure or the number of seeds per fruit.

The breeding (in 1991–1996) and wintering (1991/1992–1993/1994) avian community were surveyed in a suburban wood (29.27 ha) in Wrocław city (SW Poland). The 1992 breeding season began together with a drastic clearance of the compact undergrowth with the use of heavy machinery. A slump of abundance of the species nesting on the ground and small shrubs (≤1.5 m) followed, coupled with some modifications to their breeding behaviour, such as clustering of several singing males on the remaining bushes (Blackcap Sylvia atricapilla L.) and nesting in the piles of cut branches (Blackbird Turdus merula L.). As a result of the removal of 52% of the whole undergrowth the density of species nesting on the ground and small shrubs in 1992 was by 26% lower than in 1991 (decrease from 61.8 to 46.3 pairs 10 ha⁻¹). After 1993 a spontaneous regeneration of the bushy vegetation took place, with the ground and shrub-nesting species’ density recovering to 49.4 pairs 10 ha⁻¹ in 1996. After 1991 the park was colonized by 9 new hole-nester species, which was accompanied by the increase of density of this group (from 21.9 in 1991 to 37.9 pairs 10 ha⁻¹ in 1996). Throughout the entire study period a slight rise of density of birds nesting in tree canopies was visible (21.3 pairs 10 ha⁻¹ in 1991 and 33.8 pairs 10 ha⁻¹ in 1996). A year after the shrub clearance the wintering bird abundance was significantly lower (half of the previous numbers), with plant-eaters and insectivores hardest hit, especially Great Tit Parus major L. (average number of inidividuals per one count amounted to 59.2 in 1991/1992 and 21.9 in 1992/1993) and Blue Tit Parus caeruleus L. (respectively 37.0 and 16.0 ind.). An adequate timetable of vegetation clearance must be set up in the course of any decision-making process regarding green areas management to ensure the environmental issues are addressed properly

The optimum time of weeding during four months following spring-planting of strawberries cultivar Senga Sengana was evaluated in conditions of Central Poland. Plantations were established every year of investigations, in the last week of March. The most important annual weeds infesteing experimental plots were: Capsella bursa-pastoris, Chenopodium album, Poa annua, Stellaria media and Amaranthus retroflexus. Yielding and growth of young plants were evaluated within four months after establishing the plantation. Weight of aboveground parts and roots of strawberry plants were similar on plots weeded once (4 or 8 weeks after planting) and on plots weeded three times (4, 8, and 12 weeks after planting). Newly planted strawberry plants yielded best on the plots where weeds were controlled once, 4 weeks after establishing the plantation.
