Abstract

In this study, the anatomical features of Ballota pseudodictamnus (L.) Benth. subsp. lycia Hub.-Mor. (Lamiaceae), endemic taxa from Turkey are examined and evaluated by light (LM) and scanning electron microscopy (SEM). Different trichome types (glandular -including Lamiaceae type, capitate and peltate- and non-glandular trichomes) are observed. The densest trichome type is dendroid trichomes on the aerial part of the plant. The leaf is bifacial and amphistomatic. In the petiole, there are two collateral vascular bundles in the centre and one small vascular bundle in each corner. The prismatic crystals are present in the pith area of the stem. Results are compared with other studies in the literature. The anatomical characteristics of the stem, petiole, lamina and measurements are presented additionally trichome micromorphology is given for the first time.

Endemik Ballota pseudodictamnus subsp. lycia (Lamiaceae) Türünün Anatomisi ve Trikom Mikromorfolojisi

Abstract

Bu çalışmada Türkiye için endemik olan Ballota pseudodictamnus (L.) Benth. subsp. lycia Hub.-Mor. (Lamiaceae) taksonunun anatomik özellikleri ışık ve taramalı elektron mikroskobu (SEM) ile incelenip değerlendirilmiştir. Farklı trikom tipleri (glandular -kapitat, peltat ve Lamiaceae tipi dahil- ve glandular olmayan trikomlar) gözlenmiştir. En yoğun trikom tipi, bitkinin toprak üstü kısımlarında bulunan dendroid trikomlardır. Yaprak mezofili bifasyal ve stomalar amfistomatiktir. Yaprak sapında, merkezde iki kollateral iletim demeti ve her köşede birer küçük iletim demeti vardır. Gövde öz bölgesinde prizmatik kristaller bulunmaktadır. Sonuçlar literatürdeki diğer çalışmalarla karşılaştırılmıştır. Gövde, petiyol ve lamina anatomik özellikleri, ölçüleri bunlara ilaveten trikom mikromorfolojisi ilk kez verilmiştir.
