Praca opisuje pierwsze notowanie oraz warunki występowania porzeczki skalnej Ribes petraeum Wulfen w polskiej części Pienin, w rezerwacie Wysokie Skałki w Jaworkach. Najbliższe stanowiska gatunku znajdują się w słowackiej części pasma Małych Pienin. W Polsce porzeczka skalna rośnie najczęściej w Karpatach i Sudetach, w wyższych piętrach roślinnych, głównie w zbiorowiskach zaroślowych piętra subalpejskiego. Poza zaroślami kosówki roślina ta była obserwowana w górnoreglowych świerczynach i w zbiorowiskach ziołoroślowych piętra alpejskiego

The present paper reports the first record of Ribes petraeum Wulfen occurrence in the Polish part of the Pieniny Mts, in the nature reserve Wysokie Skałki (Fig. 1). The nearest localitions of this species were noted in the Slovakian part of the Małe Pieniny range. Natural habitats for this taxon are located in higher altitudes of the Carpathians and the Sudety Mts, especially above the timberline – in the Pinus mugo association and other shrub communities. This species was also observed in spruce forests at higher locations, and sparsely in plant communities of the alpine zone. The author presents two phytosociological relevés recorded at the site of Ribes petraeum in the upper montane zone, in the Polysticho-Piceetum association. The occurrence of the described high-montane species provides further evidence for Kulczyński’s view (1928) about the natural origin of forest on the Wysokie Skałki Mt., in the Małe Pieniny range

Pszonak pieniński Erysimum pieninicum (Zapał.) Pawł. jest jednym z endemicznych taksonów Pienin. Praca przedstawia nowe stanowiska w licznie odwiedzanym przez turystów rezerwacie przyrody „Biała Woda” w Małych Pieninach. Wstępne badania genetyczne niektórych populacji pienińskich pszonaka wykazały dość niski poziom różnorodności genowej. Przypuszczalnie nasiona trafiły do Białej Wody dzięki turystom, co pomogą zweryfikować dalsze precyzyjniejsze badania genetyczne pienińskich populacji rośliny

Erysimum pieninicum is an endemic species occurring in the Pieniny National Park. It is listed as a special care species within the Park’s area. Until 1996, it has been known only from one locality situated on the hill of Czorsztyn Castle. After 1996, more sites of this species were discovered in the Pieniny Zachodnie and Pieniny Środkowe (Właściwe) mountain ranges. In 2000, another, still existing site was found in the Małe Pieniny range (Homole Gorge) (Fig. 1). In July 2010, this species was observed in the Biała Woda Nature Reserve in two places – at the foot of Mt Smolegowa Skała (19 flowering specimens) and near Mt Kornajowska Skała (3 flowering specimens and 1 sterile one). It seems that seeds could have been brought to these localities as a result of human activity, like hiking, but this still needs to verified by genetic analysis of all populations from the Pieniny Mts

The work shows results of lysimeter research, from Jaworki near Szczawnica in the years 1992-1995, on comparison of evapotranspiration and infiltration rates from meadows supplied only by rain waters and meadows used in addition to rainfall also the capillary conductivity from the groundwater at the depth 60 cm. Based on the obtained results, it was found that under mountain conditions and in the average years occurrence of capillary movements from the groungwaters is not causing significant yield increase of grassland. However, it has decisive influence on the amount of water used for evapotranspiration, causing its considerable increase as compared to meadows without any contact with groundwater. Plants of meadows, additionally supplied by capillary movement from groundwater, use about 20 percent more water for production of 1 kg DM than the sward of meadows without groundwater. Occurrence of groundwater at 60 cm depth causes about 70 percent increase in the amount of water percolating from the aeration zone.

Studies were made in the years 1987-1991 it the IMUZ Research Station at Jaworki on elevation about 630 m. a.s.l., on the slope with northern exposition. In the trial established in 1987, yields and durability of seven varieties of Dactylis glomerata and four varieties Phleum pratense, sown with Trifolium repens (contribution of 30%), were investigated. By all time researches was applicated mineral fertilization: 180 kg of N, 80 kg of P₂O₅ and 60 kg K₂O per ha. The average yields of DM of Dactylis glomerata varieties, for four years to studies, amounted about 8,5 t ha⁻¹, whereas Phleum pratense variety yielded about 7,5 t ha⁻¹. There were no significant, statistically proved, differences in yield between studied varieties of Dactylis glomerata and Phleum pratense. Mixture with Dactylis glomerata varieties proves higher durability than Phleum pratense varieties. From Dactylis glomerata varieties the highest part in sward in 4-th year of use characterized Nera variety and the lowest part Amera variety. As concerning Phleum pratense variety the higher durability characterized Skrzeszowicka and SZD - 180.
