Morpho-anatomical investigations on Ajuga postii Briq and Ajuga relicta P.H.Davis

Abstract

In the present study morphological and anatomical features of Ajuga postii and Ajuga relicta Lamiaceae which are local endemic for Turkey have been carried out. Corolla of A. postii is dark purple-pink drying purplish and upper lip obsolescent or lost; corolla of A. relicta is cream colored when dried yellowish-beige and upper lip 1 mm, bidentate to the base. Anatomical verities have been represented in cross sections of roots, stems, and leaves of the species. A. relicta has been observed without trichomes and A. postii with sparsely non-glandular trichomes on the stems. In root cross sections of the species, sclerenchyma cells have been observed in the cortexes. In the leaf crosssections, glandular trichomes have not been observed, only non-glandular trichomes have been determined

Ajuga postii Briq ve Ajuga relicta P.H.Davis üzerine morfolojik-anatomik bir araştırma

Abstract

Yapılan çalışma ile Türkiye’de lokal endemik türler olan Ajuga postii ve Ajuga relicta Lamiaceae ’nın morfolojik ve anatomik özellikleri belirlenmiştir. Buna göre A. postii’nin korollası koyu pembe-mor kuruyunca morumsu renkli, üst dudak eksilmiş veya kaybolmuş; A. relicta’nın korollası krem rengi kuruduğunda ise sarımsı-bej rengi, üst dudak 1 mm, tabanda iki dişlidir. Anatomik özellikler çalışılan örneklerin kök, gövde ve yaprak anatomik kesitleri üzerinden verilmiştir. A. relicta’nın gövdesi üzerinde herhangi bir tüy oluşumu görülmezken, A. postii’nin gövdesi üzerinde seyrek olarak örtü tüyleri gözlenmiştir. Çalışılan taksonların kök anatomik kesitlerinde sklerenkima hücreleri korteks tabakasında belirgindir. Yaprak enine kesitlerde salgı tüyleri gözlenmezken, örtü tüyleri gözlenmiştir
