Abstract

The seed macro- and micromorphologies of four taxa (Barbarea auriculata Hausskn. ex Bornm. var. auriculata, Barbarea trichopoda Hausskn. ex Bornm., Barbarea verna (Mill.) Asch. and Barbarea vulgaris R. Br. subsp. vulgaris) belonging to Barbarea R. Br. were investigated with scanning electron microscopy (SEM). Significance of seed features as taxonomic characters including seed color, shape, winged, measures, seed coat pattern were determined. Two coat patterns were observed; irregularly-reticulate and tuberculate-reticulate, and three shapes were distinguished; broadly oblong, oblong and broadly elliptic. The results showed that the morphological characteristics of seed could be contribute as criteria to distinguish taxa. This is the first SEM study about seed surface of any Barbarea taxa.

Highlights

Brassicaceae is one of the largest family in the Angiospermae, and is distinguished by its flower and fruit characteristics
Brassicaceae comprises cosmopolitan plants that are mainly distributed in temperate zones and the Mediterranean region; this family of plants is represented by 338 genera and 3,709 species (Warwick et al, 2006)
The seed macro- and micromorphologies of four taxa; Barbarea auriculata Hausskn. ex Bornm. var. auriculata, Barbarea trichopoda Hausskn. ex Bornm., Barbarea verna (Mill.) Asch., and Barbarea vulgaris R.Br. subsp. vulgaris were investigated with scanning electron microscopy (SEM)

ÖZET Barbarea cinsine ait olan dört taksonun Auriculata, Barbarea trichopoda, Barbarea verna ve Barbarea vulgaris subsp. Vulgaris) tohum morfolojileri, taramalı electron mikroskobu (SEM) ile incelendi. Makro- ve mikromorfolojik karakter olarak tohum rengi, şekli, ölçüsü ve yüzey modeli incelendi. Düzensizretikulat ve tüberküllü-retikulat olarak iki tohum yüzeyi modeli ve geniş oblong, oblong ve geniş eliptik olarak üç tohum şekli tespit edildi. Sonuçlar Barbarea cinsinde tohumların morfolojik karakterlerinin taksonların ayrımına katkı sağlayabileceğini göstermiştir
