Abstract

In this study, anatomical characteristics of leaves and stems of 19 taxa of Thlaspi sensu lato, 9 of which are endemic to Turkey, were investigated in order to determine taxonomic relationships among the studied taxa. The anatomical characteristics of all taxa were determined and assessed using the cluster analysis and the principal component analysis. The transverse sections of the leaves and stems exhibited various diagnostic characters in terms of the pattern of epidermal cell and mesophyll layers, the number and size of vascular bundles, and the thickness of the cortex and endodermis. Important differences were detected in number, size, and index of stomata, and in epidermal cell wall structures in the adaxial and abaxial surfaces. The results showed that the compared anatomical characteristics among taxa are partially compatible with their sectional delimitation in their traditional rank in The Flora of Turkey and the East Aegean Islands. The results also point out that some taxonomic re-arrangements may be required.

Özet

Bu çalışmada, 9'u Türkiye için endemik olan 19 Thlaspi sensu lato taksonunun yaprak ve gövde anatomik karakterleri, taksonlar arasındaki taksonomik ilişkileri belirleme amacıyla tanımlanmıştır. Tüm taksonların anatomik karakterleri belirlendi ve kümeleme analizi ve temel bileşen analizi kullanılarak değerlendirildi. Yaprakların ve gövdelerin enine kesitleri epidermal hücre ve mezofil tabakalarının yapıları, vasküler demetlerin sayısı ve boyutu, korteks ve endodermisin kalınlığı açısından çeşitli teşhis karakterleri gösterdi. Ayrıca, adaksiyal ve abaksiyal yüzeylerde stomaların sayı, boyut ve indeksinde ve epidermal hücre duvarı yapılarında önemli farklılıklar saptandı. Bu sonuçlar taksonlar arasındaki karşılaştırılmış anatomik özelliklerin Türkiye Florası ve Doğu Ege Adaları'ndaki geleneksel sıralamasındaki seksiyon sınırlamaları ile kısmen uyumlu olduğunu göstermektedir. Elde edilen veriler ayrıca bazı taksonomik yeniden düzenlemelerin gerekli olabileceğine işaret etmektedir.
