The morphology and variability of pollen of Rosa pendulina L. were studied. The material came from 10 native localities of this species. 300 pollen grains were examined. It was established that the diagnostic features of pollen grains of R. pendulina L. were: an elongated, narrow operculum, a poorly developed exine sculpture, long ectocolpi (a low value of the apocolpium index), and the predominance of grains elongated in shape. The results obtained usually correspond to data supplied by other palynologists. A statistical analysis of 10 quantitative grain characteristics showed their variability to be rather low. The highest variability was found to occur in two traits connected with d (the distance between the apices of two ectocolpi). Statistical studies revealed dependences among the grains from the 10 analysed localities

Wild growing rose species are of great importance as a source of pollen for insects. Oil extracted from the petals of various Rosa species is used in perfumery, cosmetic industry, and therapeutics. In our study, we compared the flowering duration and flower lifespan, the number of stamens and pistils, the mass and size of pollen grains as well as the anatomical features of the petals of four Rosa species: R. canina, R. ×damascena, R. gallica, and R. rugosa. Moreover, we examined the pollen loads collected by bumblebees foraging on rose flowers in order to determine the attractiveness of pollen of this genus to insects. We showed the flower lifespan to vary (3.5–8 days) in the roses studied and revealed high variation in the number of stamens (82–260) and pistils (17–65) as well as in the mass of pollen produced. The flowers of R. rugosa produced the highest amount of pollen (26.7 mg per flower), while the flowers of R. canina the least (3.3 mg per flower), which is associated with differences in the number of stamens developed in the flowers between these species. The largest pollen grains were found in R. ×damascena and R. gallica. We demonstrated that R. ×damascena produces the thickest petals and that scent-emitting papillae found on the adaxial surface of the petals differ in size and shape in the rose species investigated.

The main aim of the study was to determine which of the viability and germination capacity of pollen grains estimation methods are optimal and to test if the studied sections and species within the Rosa genus are differentiated in pollen viability andgermination capacity. We analysedandcomparedpollen grains of 14 wild Rosa species using 5 viability tests and13 various liquidandagar media. Viability of pollen grains in the majority of the examinedspecies was greater than their germination capacity. The most viable pollen grains were foundin R. gallica (section Gallicanae), where average of 5 viability tests is 90.69%, andin R. pendulina (section Rosa) – 86.85%. Species from section Caninae have a lower level of viability (from 60.59% in R. rubiginosa to 31.23% in R. inodora). Pollen of species from sections Gallicanae (R. gallica; to 63.4%) and Rosa (R. pendulina; to 47.21%) germinatedmuch better than the pollen of the majority of species from section Caninae (with the exception of R. zalana; to 47.22%). The examinedpollen grains germinatedmost numerously on agar medium with 1.5% agar+15% sucrose+50 ppm boric acidandliquidmed ium with 15% sucrose+ 50 ppm boric acid. Following deep-freeze storage (–25°C) for six months, the pollen grains of nine selected species (with the exception of R. rubiginosa) showed viability higher or similar to that before storage.
