Abstract
Wild pear (Pyrus eleagnifolia) is a naturally grown species mainly in inner Anatolia and its edible small fruits are traditionally consumed by local peoples and are called “Ahlat” in Turkey. Its seedlings are also used as rootstock for commercial pear cultivars. In this study, we reported first time pomological characteristics and biochemical compositions in fruits of a wide number selected wild pears genotypes (Pyrus eleagnifolia Pall.) from inner Anatolia. The obtained results revealed that there were significant differences among wild pear genotypes for all analyzed parameters. Fruit weight, total phenolics, total acidity and total sugar contents of the fruits varied from 4.71 to 27.09 g, 42.79 to 119.14 mg GAE/100 g, 0.20 to 1.40 g/100 g and 8.36 to 19.31 g/100 g, respectively. Considering these values, it was concluded that naturally grown wild pears of Anatolia with their rich salubrious biochemical compounds could reliably be used as a food source for humans.
Zusammenfassung
Die Ölweidenblättrige Birne kommt hauptsächlich im Inneren Anatoliens natürlich vor und ihre genießbaren, kleinen Früchte werden traditionell von den ortsansässigen Bewohnern verzehrt. Die Früchte werden in der Türkei „Ahlat“ genannt. Ihre Sämlinge werden ebenfalls als Unterlagen für kommerziell angebaute Birnensorten verwendet. In dieser Untersuchung berichteten wir erstmals über pomologische Eigenschaften und biochemische Zusammensetzungen einer umfangreichen Anzahl an Früchten ausgewählter Wildbirnen-Genotypen (Pyrus eleagnifolia Pall.) aus dem Inneren Anatoliens. Die gewonnenen Ergebnisse zeigten, dass es zwischen den Genotypen der Wildbirne bei allen untersuchten Parametern signifikante Unterschiede gab. Das Fruchtgewicht, der Gesamt-Phenolgehalt, die Gesamt-Säure und der Gesamt-Zuckergehalt der Früchte variierten jeweils zwischen 4,71 und 27,09 g, von 42,79 bis 119,14 mg GAE/100 g, von 0,20 bis 1,40 g/100 g und von 8,36 bis 19,31 g/100 g. Diese Werte lassen den Schluss zu, dass natürlich gewachsene Ölweidenblättrige Birnen aus Anatolien mit ihren gesunden, biochemischen Inhaltsstoffen zuverlässig als Nahrungsquelle für den Menschen genutzt werden könnten.
