Bazı Cardamine (Brassicaceae) Taksonlarının Tohum Yüzey Mikro Şekilleri ve Taksonomik Önemi

The seed exomorphic characteristics of four taxa (Cardamine graeca, C. impatiens subsp. impatiens, C. raphanifolia and C. uliginosa) belonging to Cardamine were investigated with scanning electron microscopy (SEM). This study presents exomorphic characteristics, including seed colour, shape, winged, measures, seed coat pattern. Four coat patterns were observed; regularly reticulate, irregularly-reticulate, blister and tuberculate-reticulate, and two shapes were distinguished; broadly oblong and oblong. The results showed that the morphological characteristics of seed could contribute as criteria to distinguish taxa. This is the first study in which the seed surface of any Cardamine taxa growing in Turkey is studied with SEM.
