Abstract

In this study, the comparative anatomical, palynological, and fruit micromorphological characteristics of the endemic Türkiye species Prangos abieticola and P. heyniae were investigated. Anatomical analyses were carried out on transverse sections of the stem, peduncle, pedicel, ray, and fruit, and the structural features were evaluated in detail and presented in tables. Palynological investigations were conducted using light microscopy and scanning electron microscopy (SEM). Measurements of the polar and equatorial axes, colpus width and length, pore width and length, as well as exine and intine thicknesses were taken, and P/E ratios were calculated. The pollen grains of both species were perprolate in shape, with a trizonocolporate aperture type, and exhibited rugulate surface ornamentation. Fruit micromorphological features were examined using SEM, revealing distinct surface ornamentation patterns between the two species. The results indicate that palynological characters provide limited taxonomic resolution, whereas anatomical and especially fruit micromorphological characters offer reliable and diagnostic features for distinguishing P. abieticola and P. heyniae.

Özet

Bu çalışmada, Türkiye endemiği Prangos abieticola ve P. heyniae türlerinin karşılaştırmalı anatomik, palinolojik ve meyve mikromorfolojik özellikleri incelenmiştir. Anatomik analizler, gövde, pedunkul, pedisel, ray ve meyveye ait enine kesitler üzerinden gerçekleştirilmiş; yapısal özellikler ayrıntılı olarak değerlendirilerek tablolar hâlinde sunulmuştur. Palinolojik incelemeler, ışık mikroskobu ve taramalı elektron mikroskobu (SEM) kullanılarak yürütülmüştür. Polenlerin polar ve ekvatoral eksenleri, kolpus genişliği ve uzunluğu, por genişliği ve uzunluğu ile ekzin ve intin kalınlıkları ölçülmüş ve P/E oranları hesaplanmıştır. Her iki türün polenleri perprolat şekilli, apertür tipi trizonokolporat olup, yüzey ornamentasyonu rugulat olarak belirlenmiştir. Meyve mikromorfolojik özellikler SEM kullanılarak incelenmiş ve iki tür arasında farklı yüzey ornamentasyonlarının bulunduğu ortaya konulmuştur. Elde edilen sonuçlar, palinolojik karakterlerin taksonomik ayırımda sınırlı bir çözünürlük sağladığını; buna karşılık anatomik ve özellikle meyve mikromorfolojik karakterlerin P. abieticola ve P. heyniae türlerinin ayırt edilmesinde güvenilir ve tanılayıcı özellikler sunduğunu göstermektedir.
