Effects of fungicidal concentrations of sulphur, dichlone, ferbam, and captan on sweet cherry (Prunus avium L.) pollen germination and growth were studied in artificial media. Sulphur did not reduce the germination of pollen. Dichlone and ferbam reduced germination from 53.0 per cent to 47.1 per cent and 40 per cent, respectively, reductions which were significant statistically. Sprayed at 0.2 pound/100 gallons or less, captan did not reduce germination. Captan, sprayed at 2 pounds/100 gallons, almost entirely prevented pollen germination, and arrested the elongation of pollen tubes.

The aim of this study was to evaluate and compare the content of a number of bioactive compounds and antioxidant activity of fruits of selected local and commercial sweet cherry (Prunus avium L.) cultivars. The experiment showed that the selected cultivars of sweet cherries differ significantly in the content of polyphenolic compounds and carotenoids. The fruits of commercial sweet cherry cultivars were, on average, richer in polyphenols (the sum of phenolic compounds determined chromatographically), flavonoids, as well as anthocyanins and were characterized by higher antioxidant activity when compared to the local, traditional cultivars. In the group of the traditional sweet cherry cultivars, particular attention could be paid to Black Late cv., showing the highest antioxidant activity of fruits. In the group of commercial sweet cherry cultivars, Cordia and Sylvia fruits could be recognized as being rich in bioactive compounds with high antioxidant activity. Yellow skin cultivars were characterized by the highest concentrations of carotenoids. Strong positive correlations between the identified bioactive compounds and antioxidant activity of fruits were also found. Although different cultivars of sweet cherries show a high variability in phenolics and carotenoids profiles as well as in the antioxidant activity of fruits, they all should be, similarly to other types of cherries, recognized as a rich source of bioactive compounds with an antioxidant potential.

The paper presents results of a three-year study of self-(in)compatibility in four economically important sweet cherry genotypes - ?Karina?, ?Kordia?, ?Regina? and ?Summit?, under agro-environmental conditions of Western Serbia. Determination of S-RNase genotype, microscopic observation of the pollen tube growth rate and assaying of the fruit set level after self-pollination were used to assess the genotypes. ?Kordia? (S3S6), ?Regina? (S1S3) and ?Summit? (S1S2) are self-incompatible genotypes, with a considerable number of pollen tubes ending the growth in the middle third of the style and lack of fruit set. ?Karina?, as S3S4 genotype, behaved as self-compatible, since its pollen tubes reached the base of the style and ovary, penetrating the nucellus. In addition, fruit set for ?Karina? was recorded in all three years of study (40.26%, 18.79% and 21.81%, respectively).
