Seed micromorphology of Ornithogalum refractum and Ornithogalum fimbriatum Hyacinthaceae from Turkey

Abstract

In this study contributions on taxonomy of Ornithogalum taxa in recent years were given. The micromorphological characters of seed surfaces of Ornithogalum fimbriatum Willd. and Ornithogalum refractum Kit et Schlecht. were scanned by scanning electron microscope and were given for the first time. The outer periclinal walls were flat with smooth surface and there were intense fibrous pattern in Ornithogalum fimbriatum and Ornithogalum refractum. The cells of testa were mostly rectangular shape in Ornithogalum refractum while square or weakly curved similar to square shape in Ornithogalum fimbriatum

Türkiye’de Ornithogalum refractum ve Ornithogalum fimbriatum Hyacinthaceae ’un tohum mikromorfolojisi

Abstract

Bu çalışmada, son yıllardaki Ornithogalum taksonlarının taksonomisi üzerinde katkılar verilmiştir. Ornithogalum fimbriatum Willd. ve Ornithogalum refractum Kit et Schlecht.’in tohum yüzeylerinin mikromorfolojik karakterleri scanning elektron mikroskobu ile taranmıştır ve ilk defa verilmiştir. Ornithogalum fimbriatum ve Ornithogalum refractum testa hücrelerin dış yan çeperleri düz ve düz yüzeyli ve yoğun fibrilli yapılara sahiptir. Testa hücreleri çoğunlukla Ornithogalum refractum’da dikdörtgenimsi şekilliyken, Ornithogalum fimbriatum. ‘da ise kare şekilli veya hafifçe kıvrımlı kareye benzer şekillidir
