Romanian wild cherry genotypes (Prunus avium var. sylvestris Ser.) suitable for processing

Abstract

This paper presents the important features of indigenous wild cherry genotypes suitable for processing. The research took place between 2017–2020, having ten Romanian wild cherry genotypes as study material. The harvesting maturity was recorded in the first decade of June for the early cultivar (G10) and decades two and three of June for the other studied genotypes, all of them with a middle season maturation. The number of days between the end of the flowering and the maturation was between 54 days (G10) and 66 days (G9). The average weight of the fruit and the equatorial diameter varied between 2.1 g and 13.80 mm for G4, respectively, and 5.5 g and 21.35 mm for G10. The proportion (%) between the pulp and waste (stone and peduncle) was measured as 81.95% pulp (G4) and 93.64% pulp (G10). The values of the soluble dry substance content were between 13.1–24.0 °Brix, the titratable acidity was between 0.48–1.16 mg malic acid/100 mL juice and the total content of the polyphenols was between 229.00–720.00 mg GAE/100 mL fresh juice. In terms of the bitter taste intensity, G10 has a weak intensity, G3, G7, G8 and G9 have an average intensity and G1, G3, G4, G5 and G6 have a high intensity.
