Abstract

Bu çalışmada, Türkiye için endemik bir tür olan Marrubium trachyticum Boiss.’un taramalı
elektron mikroskobu (SEM) kullanılarak gövde, yaprak, kaliks ve fındıkçığının
mikromorfolojik özellikleri ve ışık mikroskobu kullanılarak kök, gövde ve
yaprak anatomisi araştırıldı. M.
trachyticum’un gövde, yaprak ve kaliksi üzerinde eşit olmayan ışınlı
stellat tüyler ve dallanmış tüyler gözlendi. Bununla beraber, M. trachyticum’un bu vejetatif organları
üzerindeki salgı tüylerinin dağılışı ve yoğunluğu, örtü tüylerinden daha azdır.
Türün olgun fındıkçıkları, ovat şekilliydi ve yüzey süslemesi penta-hexagonal
colliculate (beşgen-altıgen şekilli kabartılı)’dir. Anatomik sonuçlara göre,
araştırılan tür, sekonder kök yapısına sahiptir. Gövdenin belirgin bir
kollenkima tabakasına sahip olduğu gözlendi. Gövde enine kesiti dört köşelidir
ve ince bir kutikulaya sahip oval veya dikdörtgen epidermis hücreleri ile
çevrilidir. M. trachyticum’un
yaprakları bifasiyaldir (dorsiventral). Bu tür, yaprağın hem alt hem de üst
yüzeyinde anomositik tip stomalara sahiptir.

MICROMORPHOLOGICAL AND ANATOMICAL CHARACTERS OF THE TURKISH ENDEMIC Marrubium trachyticum Boiss. (LAMIACEAE)

Abstract

In the present study, micromorphological characters of stem,
leaf, calyx and mericarp of the Turkish endemic Marrubium trachyticum Boiss were investigated using scanning
electron microscopy (SEM) and the anatomy of root, stem and leaf using light
microscopy (LM). Stellate trichomes with unequal rays and branched hairs were
observed on the stem, leaf and calyx. The distributions and densities of
glandular trichomes on these vegetative organs were less than the eglandular trichomes. The mature mericarps of
the species were ovate in shape and sculpturing pattern was penta-hexagonal
colliculate. According to the anatomical results, M. trachyticum has secondary root structure. The stem has a
distinct collenchyma layer. The stem is surrounded by oval or rectangular epidermal
cells with a thick cuticle and is quadrangular in shape. The leaves are
bifacial (dorsiventral) with anomocytic stomata in both the upper and the lower
surfaces.
