Capsella bursa-pastoris Medik. ve Capsella rubella Reuter taksonlarının (Brassicaceae) taksonomik, morfolojik ve musilaj özellikleri üzerine notlar
Bu çalışmada, Türkiye'de yetişen Capsella bursa-pastoris ve Capsella rubella taksonlarının taksonomik, morfolojik ve müsilaj karakterleri üzerine incelemeler yapılmıştır. Özellikler bireylerin çiçekli ve meyveli dönemlerinde elde edilmiştir. Örneklemeler 13 lokasyonda yapılmıştır. Morfolojik incelemelerde, çalışılan taksonların Türkiye Florasında bildirilen deskripsiyonları, 200’den fazla örneğin kapsamlı değerlendirilmeleri ışığında yeniden gözden geçirilmiştir. Buna ilaveten, tohumların yüzeyleri taramalı elektron mikroskobu ile mikromorfolojik olarak incelenmiştir. Ayrıca, tohum müsilaj yapıları detaylı olarak incelenmiştir. Çalışılan taksonlardaki müsilaj, pektin veya selüloz yapısındaydı. Kolumella şekli belirgin veya düzleşmişti. Dahası, incelenen taksonların toprak yapıştırma kapasiteleri 248 mg ile 344 mg arasında değişmiştir. Tohumlardaki müsilajın oluşumu, Capsella taksonlarının dağılma ve kolonizasyonunda önemli bir adaptif özelliği sağlayabilir.
Notes on the taxonomical, morphological and mucilage features of Capsella bursa-pastoris Medik. and Capsella rubella Reuter taxa (Brassicaceae)
In this study, examinations on the taxonomical, morphological and mucilage characters of theCapsella bursa-pastoris and Capsella rubella taxa growing in Turkey were performed. The propertieswere acquired at the flowering and fruiting periods of inhabitants. The samplings were made of 13locations. In morphological revisions, descriptions reported in Flora of Turkey of the studied taxawere reviewed in view of the comprehensive assessments over 200 samples. In addition, surfaces ofthe seeds were studied micromorphologically with scanning electron microscope. Also, seedmucilage structures were examined in detail. The mucilage in the studied taxa was in the pectin orcellulose structure. The columellae figures were prominent or flattened. Furthermore, soil adhesioncapacities of the examined taxa varied between 248 mg and 344 mg. The occurrence of the mucilagein seeds may provide an important adaptive feature in dispersal and colonization of Capsella taxa.
