Micromorphological observations on the seed surfaces of some Onobrychis adans. (Leguminosae) taxa from Turkey

Bu çalışmada Anadolu'da geniş çeşitlilik gösteren Onobrychis türlerinin tohum örtüsü yüzey karakterlerinden, tarayıcı elektron mikroskobu (SEM) kullanılarak tür düzeyinde ayırıma gidilmesi amaçlanmıştır. İncelenen 11 taksonun tohum yüzeylerinin yüksek büyütmelerde teşhise yönelik farklılıklar taşıdığı gözlenmiştir. Sözkonusu yüzey-yapısal özellikler aynı zamanda, yakın ilişkili türlerin taksonomik olarak sınırlandırılmasında kullanışlı ilave veriler olarak değerlendirilebilir. Fakat, tür üstü taksonomik kategori olarak seksiyon düzeyinde genel karakteristiği temsil eden ayırtedici ortak bir yüzey yapılanması tespit edilmemiştir.

Türkiye'deki bazı Onobrychis adans. (Leguminosae) taksonlarının tohum yüzeylerinde mikromorfolojik gözlemler

This study was initiated to discriminate some Onobrychis taxa having great diversity in Anatolia from their seed-coat sculptures with SEM (Scanning Electron Microscopy). Diagnostic differences in high magnifications were observed on the seed surfaces of eleven taxa examined. The patterns found in close related species may also be useful as additional parameters to the delineations but no any general characteristics examplified on the section level were identified.
