Alyssum strigosum s.l. (Brassicaceae)’un Morfolojik, Anatomik ve Palinolojik Özellikleri

Öz

Alyssum strigosum Banks & Sol. subsp. strigosum ve A. strigosum Banks & Sol. subsp. cedrorum (Schott & Kotschy) Dudley taksonlarının morfolojik, anatomik ve palinolojik özellikleri, bu çalışma ile ayrıntılı olarak ortaya konulmuştur. Köklerin enine kesitleri, iki alt türün, primer yapısında olduğu gibi benzer anatomik karakterlere sahip olduğunu gösterdi. Gövde bölümleri tipik dikotiledon gövde anatomik yapısını yansıtmış ve türlerin oval şekilli korteks parankimine sahip oldukları belirlenmiştir. Gövdede bulunan damar demetleri, incelenen türlerin her ikisinde de tek sıra halinde düzenlenmiştir. Mezofil türü eş yüzeyli olarak tespit edildi. İncelenen türler monad, isopolar, prolat ve trikolpat polen tanelerine sahiptir. İncelenen iki tür için ekzin heykel retikülat olarak gözlenmiştir. Sonuç olarak, Alyssum strigosum'daki anatomik ve palinolojik özellikler, alttürlerin ayrılmasını destekleyici niteliktedir.

Morphological, Anatomical and Palynological Features of Alyssum strigosum s. l. (Brassicaceae)

Öz

Alyssum strigosum Banks & Sol. subsp. strigosum and A. strigosum Banks & Sol. subsp. cedrorum (Schott & Kotschy) Dudley, which are two subspecies of Alyssum strigosum with their morphological, anatomical, palynological traits, were presented in detail with this study. The anatomical analysis has been carried out using handmade sections. The transverse sections of roots showed that two subspecies have similar anatomical characters as with primer structure. The sections of stem were reflected the typical dicotyledonous stem anatomical structure and were determined that species have oval shaped cortex parenchyma. The vascular bundles in stem were arranged in one row both examined species. The mesophyll type was detected as equifacial. The examined species have monad, isopolar, prolate and tricolpate pollen grains. For two examined species, exine sculpture were observed as reticulate. As a conclusion, the characteristics of anatomical and palynological in Alyssum strigosum have been showed the supporting the separation of subspecies.
