Abstract
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.
Highlights
Oleaster-leafed pear (Pyrus elaeagrifolia Pall. subsp. elaeagrifolia) is one of the most widely known wild grown pear species, which is a member of the Rosaceae family
The goats are live in Pyrus elaeagrifolia Pall. subsp. elaeagrifolia growing areas but there are no impact on the populations of Pyrus
Pyrus elaeagrifolia Pall. subsp. elaeagrifolia fruits were characterized in terms of morphological and biochemical properties
Summary
It is small to medium-sized tree and native to central, eastern and southern Anatolia region in Turkey including cities such as Amasya, Ankara, Antalya, Artvin, Bolu, Erzincan, Erzurum, Gumushane, Kahramanmaras, Kastamonu, Kayseri, Konya, Kutahya, Mersin, Mus, Nigde, Sivas, and Van [1]. Trees occur in a scattered distribution pattern as single individuals or in small groups in different parts of Turkey and Europe. Oleaster-leafed pear is extremely light-demanding and has weak competitive abilities. Elaeagrifolia growing areas but there are no impact on the populations of Pyrus. The goats are live in Pyrus elaeagrifolia Pall. This is an important aspect for the population conservation
