A Comprehensive Micromorphological and Anatomical Study on the Poisonous Plant Cionura erecta (L.) Griseb. (Apocynaceae: Asclepiadoideae)

Abstract

Cionura erecta (L.) Griseb., named as Babrik in Türkiye, is one of the widespread taxa of Apocynaceae, which is known for its toxicity as well as its common therapeutic use. This study aimed to contribute to the systematics of C. erecta by examining the stem, petiole, lamina and flower parts of the species in detail, for the first time, using scanning electron microscopy (SEM) and light microscopy. SEM examinations determined that the surface of vegetative parts was crisped hairy, leaf epicuticular wax was striate, and colleters were in petiolar, laminar and calycine positions, and each was defined as standard type consisting of a short, non-secretory stalk, and a conical, undivided main secretory head. The presence of collenchyma cells and scattered sclerenchyma cell groups in the stem, bicollateral vascular bundles, laticifers and druse crystals in all vegetative portions, and paracytic, anomocytic, and anisocytic stomata on the amphistomotic and equifacial leaf were determined as the most characteristic anatomical features. The obtained results revealed that anatomical and micromorphological characters could be used to contribute to the morphological characters in the identification of C. erecta.

Öz

Türkiye’de Babrik adıyla bilinen Cionura erecta (L.) Griseb., Apocynaceae familyasının geniş yayılışlı taksonlarından biri olup zehirli olmasının yanı sıra yaygın tedavi edici kullanımı ile de bilinmektedir. Bu çalışma ile C. erecta’nın gövde, petiyol, yaprak ayası ve çiçek kısımları taramalı elektron mikroskobu (SEM) ve ışık mikroskobu ile ilk kez detaylı bir şekilde incelenerek türün sistematiğine katkı sağlanması amaçlanmıştır. SEM incelemelerinde vejetatif kısımların yüzeyinin kıvrık tüylü, yaprak epikutikular mum tabakasının çizgili olduğu, colleter salgı yapılarının petiyol, yaprak ayası ve kaliksin üzerinde konumlandığı ve herbirinin kısa, salgı yapmayan bir sap ve konik, bölünmemiş salgı yapan bir baş kısmından oluşan standart tip olarak tanımlandığı belirlendi. Gövdede kollenkima hücreleri ve dağınık sklerenkima hücre gruplarının bulunması, tüm vejetatif kısımlarda bikollateral iletim demetleri, latisiferler ve druz kristallerinin varlığı, ekvifasiyal ve amfistomotik yaprakta ise parasitik, anomositik ve anizositik stomaların varlığı en karakteristik anatomik özellikler olarak belirlendi. Elde edilen sonuçlar, anatomik ve mikromorfolojik karakterlerin C. erecta’nın tanımlanmasında morfolojik karakterlere katkı sağlamak amacıyla kullanılabileceğini ortaya koymuştur.
