Some morphological and fruit characteristics of naturally grown Pyrus elaeagrifolia Pall. of Kayseri Province (Central Anatolia, Turkey)

Oleaster-leafed pear (Pyrus elaeagrifolia Pall. subsp. elaeagrifolia) fruits are used for food and dietary supplements in Turkey, and seedlings are used as rootstock for pear cultivars. Information on the effect of genotypes on oleaster-leafed pear fruit characteristics is needed in order to optimize production of quality food and dietary supplements. The characteristics of oleaster-leafed pear fruits relative to genetic background were evaluated from 16 wild grown oleaster-leafed pear genotypes at eastern Turkey. Genotype influenced ripening dates, fruit weight, fruit length/width ratio, fruit pedicel length, fruit flesh texture, fruit firmness, the number of seeds per fruit, soluble solid content, titratable acidity, total phenolic content, total flavonoid content and antioxidant activity. Analysis of the data obtained from 16 oleaster-leafed pear genotypes demonstrated a highly significant influence of genotype on fruit characteristics. The genotypes G12, G13 and G9 had the highest fruit weight (19.22, 18.54 and 18.30 g) and G9 the highest total phenolic content (122 mg gallic acid equivalent/100 g fresh fruit). The genotypes G3, G5, G11 and G13 had the slightly sandy fruit flesh texture and those genotypes may be good selections for processing and producing health oleaster-leafed pear products.

Cerasus prostrata (Lab.) Ser. is quite widespread in some regions of Turkey. It is a wild and deciduous fruit species. The species is commonly encountered in Central Anatolia over the foothills of Erciyes Mountain. In this study, some fruit and leaf characteristics of 30 C. prostrata genotypes collected from the foothills of Erciyes Mountain were determined and genetic diversity among them was presented. Fruit weights of the genotypes varied between 0.66–0.23 g and fruit flesh ratios varied between 84.59–63.11%. Leaf width, leaf length and petiole lengths of the genotypes respectively varied between 1.61–0.68 cm; 4.02–1.82 cm and 0.60–0.28 cm. In genetic analyses, 17 ISSR primers were used and 115 bands were obtained. Of these bands, 98 were polymorphic. All genotypes were distinguished from each other. Relatively high variation was identified between the genotypes and similarity levels varied between 0.70–0.95. Current findings revealed significant information for the preservation and appraisal of C. prostrata. Further studies are recommended for breeding and protection of this species.
