Türkiye’den Bazı Iris L. Taksonlarının Tohumları Üzerinde Morfolojik ve Anatomik Gözlemler

Öz

Bu çalışma Türkiye’de dağılım gösteren bazı Iris taksonlarına ait (I. suaveolens, I. sintenisii, I. foetidissima ve I. germanica) tohumların morfolojik ve anatomik özelliklerinin taksonomik değerlendirmesini içerir. Tohumların boyutu, şekli, rengi ve yüzey ornamentasyonları ışık ve taramalı elektron mikroskobu ile çalışılmıştır. Testa ve parankima tabakalarının yapı ve kalınlığı anatomik olarak incelenmiştir. Elde edilen bulgular, incelenen taksonlara ait tohumların renk, şekil, testa yapısı ve kalınlığına ait özelliklerin bazı açılardan farklı olduğunu göstermektedir. Ayrıca, yüzey ornamentasyonları türler arası seviyede incelenilen taksonlar için kısmen farklıdır. Sonuç olarak, incelenen tohum morfolojik ve anatomik karakterlerinin bazı istisnalar ile varyasyonlar gösterdiği ve bu durumun taksonomik öneme sahip olduğu tespit edilmiştir.

Morphological and Anatomical Observations on Seeds of Some Iris L. Taxa from Turkey

Öz

This study includes on the taxonomic evaluation of morphological and anatomical features of seeds belonging to Iris taxa, which are I. suaveolens, I. sintenisii, I. foetidissima and I. germanica scattered in Turkey. Morphological features like dimension, shape, colour, and surface ornamentation types of seeds have studied by light and scanning electron microscopes. The structure and thicknesses of testa and parenchyma layers in seeds have examined anatomically. The obtained results show that the color, shape, testa structure and thickness of the seeds of the examined taxa are different in some respects. Furthermore, the surface ornamentations are somewhat diverse for the studied taxa at the interspecific level. As a result, it has been determined that the examined morphological and anatomical characteristics of the seeds show variations with some exceptions, and this situation has a taxonomic importance.
