The nectaries anatomical features of nine species of Pomoideae subfamily Aronia melanocarpa Ell., Cotoneaster horizontalis Decne, C. praecox Vilm.-Andr., C. lucida Schlecht., Crataegus monogyna Jacq., C. coccinea L., C. crus-galli L., Sorbus aucuparia L., Sorbus intermedia Pers. were compared. The flower longitudinal sections by means of vibratome and semithin slides by use of ultramicrotome were made. The thickness of nectary epidermis, glandular layer and the structure of subglandular layer as well as the run of vascular bundles were studied. It was stated that the height of epidermis cells and the thickness of their wall were approximate in the most investigated taxons. Stomata occurred in the nectaries of all species. They were located on a level with the epidermis cells in Aronia and Sorbus genera, in small hollows in Cotoneaster and considerably below the level of epidermis cells in Crataegus. The thickness of glandular layer was approximate for each genera. Sorbus intermedia and the species of Crataegus genus wer distinguishable by the thickest nectaries. The concentration of brachysclereids occurred in subglandular tissue of Crataegus crus-galli and of Sorbus both species. Vascular bundles, stocking the nectary, mostly consisted of phloem and xylem, but in Aronia, Cotoneaster praecox and C. lucida only phloem was noticed. The dependence between thickness of glandular layer, studied anatomical features and the volume of secreted nectar is discussed.

Pollen grain of 16 species and three hybrids of the genus Amygdalus L., representing two subgenera and two sections distributed in Iran were examined by light and scanning electron microscopy. All pollen grains are tricolporate. The shape of grains varies from subprolate through prolate. Regarding outline, in polar view, pollen grains are triangular-circular and in equatorial view, elliptic. Regarding sculpturing of exine, the frequent type like many members of family Rosaceae is striate with or without perforations that can be subdivided into three subtypes: type I (A-B), type II (A-B) and type V. In three species, A. trichamygdalus, A. spinosissima and A. orientalis, exine sculpture type is completely different. In the first species is rugulate, in the second species is reticulate and in A. orientalis, it is gemmate-perforate. Ornamentation of ridges (muri) in the striate sculpture is parallel to ectocolpus. Number of perforations in tectum, diameter of them, striae intervals and the thickness of ridges varies among studied taxa. The striae have different depth and slope. Results showed that among pollen grain characters, shape is useful character solely for separating of taxonomic ranks in Iranian Amygdalus specially in subgeneric or section level.

Leaf hair types in Polish selected taxa from Potentilla subsect. Collinae Juz., i.e. P. collina Wibel s.str., P. silesiaca Uechtr. P. thyrsiflora Hillsen ex Zimmeter, P. wimanniana Gilnther and Schummel, P. leucopolitana P.J. Milller and P. leucopolitana P.J. Milller x P. incana P. Graebner were studied. A total of five unicellular hair types could be distinguished, based on the structure of the hair: straight, involuted, crispate, curved and stellate. The occurrence of involuted, curved and stellate hairs was observed for the first time for the majority of investigated taxa. There is a variation in density, position, as well as in the number of arms of stellate hairs. Although they are difficult to see without a stereo microscope, these differences seem to be systematically important. The study of hair types on surfaces of leaves supports the opinion that P. collina s.lato is a hybrid between P. argentea L. s.la-to, P. tabernaemontani Ascherson and P. incana P. Gaertner. Hairs form consistent characters which are highly suited for systematic purposes. The key to Polish taxa based on leaf hair types is given as well.

Seeds of Pyrus calleryana were sampled from 11 stations located in Poznań green areas. Three of them represented cultivar ‘Capital’, whereas the remaining eight represented cultivar ‘Chanticleer’. The viability of seeds was qualified by means of tetrazolium test. The results of staining test showed that viability of Callery pear seeds was high and ranged from 90 to 100%.
