Abstract

With this study fruit width-length measurements, weights and surface morphologies of some taxa belonging to Asteraceae family distributed in Türkiye were studied. The aim of the study was to reveal the fruit morphological characteristics and differences between the taxa of Tragopogon buphthalmoides, Dittrichia viscosa, Dittrichia graveolens, Tripleurospermum caucasicum, Kemulariella caucasica, Leontodon hispidus subsp. hispidus, Jurinea consanguinea and Jurinea moschus. Widths and lengths of the fruits were measured with Leica EZ4 microscope and digital caliper. Fruit weights were weighted out with Dikomsan precision scales. The stereomicroscope to determine the morphological characteristics of the fruits was also used. Scanning Electron Microscopy (SEM) in USKIM (Center for University and Industry Collaboration) was used to determine the surface morphology of the fruits. The smallest fruits were determined in Dittrichia graveolens (0.40 mm wide and 1.23 mm long), while the largest fruits were determined in Tragopogon buphthalmoides (25.88 mm long and 1.62 mm wide). The heaviest fruits were measured in Jurinea consanguinea (0.0065 gr) and the slightest fruits in Dittrichia graveolens (0.000062 gr) taxa.

TÜRKİYE İÇİN DOĞAL, BAZI ASTERACEAE TAKSONLARI ÜZERİNDE MİKROMORFOLOJİK ARAŞTIRMALAR (AKEN / SİPSELA)

Abstract

Bu çalışma ile Türkiye'de yayılış gösteren Asteraceae familyasına ait bazı taksonların meyve en-boy ölçümleri, ağırlıkları ve yüzey morfolojileri çalışılmıştır. Çalışmada; Tragopogon buphthalmoides, Dittrichia viscosa, Dittrichia graveolens, Tripleurospermum caucasicum, Kemulariella caucasica, Leontodon hispidus subsp. hispidus, Jurinea consanguinea ve Jurinea moschus taksonlarına ait meyve morfolojik özellikleri ve birbirleri arasındaki farklılıkları ortaya koymak amaçlanmıştır. Meyvelerin en ve boyları Leica EZ4 mikroskop ve dijital kumpas kullanılarak ölçülmüştür. Dikomsan hassas terazi ile meyvelerin ağırlıkları tartılmıştır. Meyvelerin morfolojik özelliklerinin belirlenmesine yardımcı olmak için stereomikroskop ile de çalışılmıştır. Meyvelerin yüzey morfolojisinin belirlenmesinde ÜSKİM (Üniversite-Sanayi-Kamu İşbirliği Geliştirme Uygulama ve Araştırma Merkezi) bünyesinde bulunan Taramalı Elektron Mikroskobu (SEM) kullanılmıştır. Çalışılan taksonlar içerisinde en küçük meyveler Dittrichia graveolens taksonunda (1.23 mm uzunluğunda ve 0.40 mm genişliğindedir), en büyük meyveler ise Tragopogon buphthalmoides taksonunda tespit edilmiştir (25.88 mm uzunluğunda ve 1.62 mm genişliğindedir). En ağır meyveler Jurinea consanguinea’da (0.0065 gr.) ve en hafif meyveler Dittrichia graveolens’de (0.000062 gr.) ölçülmüştür.
