4 Austrian varieties of rye (‘Walstaudenroggen’, ‘Echo’, ‘Schlager’ and ‘Esprit’) and one Polish variety (‘Dańkowskie Złote’) were investigated. There were differences in grains composition as well as in starch properties. Among all varieties, the best one ‘Waldstaudenroggen’ was distinguished due to a high content of soluble carbohydrates, Iow level of amylose and high molecular mass of starch. Basing on those permises it was found, that the mentioned above properties, influenced high quality of rye variety. Despite growing in different climatical conditions, the Polish variety ‘Dańkowskie Złote’ did not differ in the analysed features from the Austrian ones.
The paper reports results of a morphological study of pollen grain of three varieties of Helianthus annuus: Wielkopolski population variety and two interline hybrids Frankasol and Coril. The viability of the pollen grain was also determined. No significant differences were found between the population variety and the two interline hybrids.
