Bu çalışmada, Türkiye'de yetişen Capsella bursa-pastoris ve Capsella rubella taksonlarınıntaksonomik, morfolojik ve müsilaj karakterleri üzerine incelemeler yapılmıştır.Özellikler bireylerin çiçekli ve meyveli dönemlerinde elde edilmiştir.Örneklemeler 13 lokasyonda yapılmıştır. Morfolojik incelemelerde, çalışılantaksonların Türkiye Florasında bildirilen deskripsiyonları, 200’den fazlaörneğin kapsamlı değerlendirilmeleri ışığında yeniden gözden geçirilmiştir.Buna ilaveten, tohumların yüzeyleri taramalı elektron mikroskobu ilemikromorfolojik olarak incelenmiştir. Ayrıca, tohum müsilaj yapıları detaylıolarak incelenmiştir. Çalışılan taksonlardaki müsilaj, pektin veya selülozyapısındaydı. Kolumella şekli belirgin veya düzleşmişti. Dahası, incelenentaksonların toprak yapıştırma kapasiteleri 248 mg ile 344 mg arasında değişmiştir.Tohumlardaki müsilajın oluşumu, Capsellataksonlarının dağılma ve kolonizasyonunda önemli bir adaptif özelliğisağlayabilir.

Inthis study, examinations on the taxonomical, morphological and mucilagecharacters of the Capsella bursa-pastoris and Capsella rubella taxa growing in Turkey were performed. Theproperties were acquired at the flowering and fruiting periods of inhabitants.The samplings were made of 13 locations. In morphological revisions,descriptions reported in Flora of Turkey of the studied taxa were reviewed inview of the comprehensive assessments over 200 samples. In addition, surfacesof the seeds were studied micromorphologically with scanning electronmicroscope. Also, seed mucilage structures were examined in detail. Themucilage in the studied taxa was in the pectin or cellulose structure. Thecolumellae figures were prominent or flattened. Furthermore, soil adhesioncapacities of the examined taxa varied between 248 mg and 344 mg. Theoccurrence of the mucilage in seeds may provide an important adaptive featurein dispersal and colonization of Capsellataxa.
