INULA PEACOCKIANA (AITCH. & HEMSL.) KOROVIN'NIN YAPRAK ANATOMİSİ

Öz

Amaç: Türkiye'de "uzunandızotu" olarak adlandırılan Inula peacockiana, 2 m'ye kadar boylanabilen, sarı çiçekli, güçlü, çok yıllık otsu bir bitkidir. Asteraceae familyasına ait tıbbi değeri olan bir bitkidir. Tıbbi bitkilerin güvenli kullanımı doğru teşhislerine bağlıdır. Yaprakların anatomik özellikleri, bitkilerin doğru teşhis edilmesinde önemlidir. Bu çalışmada I. peacockiana'nın taban yaprağı, yaprak sapı ve gövde yaprağının anatomik özellikleri incelenmiştir.

Gereç ve Yöntem: Bitki materyalleri Van'dan (Türkiye) toplanmıştır. VANF Herbaryumuna bir örnek kaydedilmiştir. Anatomik çalışmalar için numuneler %70 alkolde korunmuştur. Enine ve yüzey kesitler bir jilet yardımıyla el ile alınmıştır. Mikroskobik incelemelerde kloralhidrat solüsyonu kullanılmıştır.

Sonuç ve Tartışma: Taban ve gövde yaprakları dorsiventraldir, örtü ve salgı tüyleri içerir. Her iki yaprağın orta damarı dışa doğru çıkıntı yapmıştır. Taban yapraktan farklı olarak, gövde yaprağının üst yüzeyinde daha fazla salgı tüyü, alt yüzeyinde ise örtü tüyleri bulunur. Her iki yaprakta da üst ve alt epidermada ranunculaceae tipi stomalar gözlenmiştir. Basit yay şeklindeki taban yaprak sapının enine kesiti, parankimatik hücrelere gömülü çok sayıda ayrı iletim demet içerir. Epiderma çok sayıda örtü ve salgı tüyleri taşır.

LEAF ANATOMY OF INULA PEACOCKIANA (AITCH. & HEMSL.) KOROVIN

Öz

Objective: Inula peacockiana, which is called "uzunandızotu" in Turkey, is a stout perennial herbaceous plant with yellow flowers, grow up to 2 m. It is a plant belonging to the Asteraceae family, which has medicinal value. The safe use of medicinal plants depends on their correct diagnosis. The anatomical features of the leaves are valuable in diagnosing plants correctly. In this study, the anatomical features of the basal leaf, petiole and cauline leaf of I. peacockiana were investigated.

Material and Method: Plant materials were collected from Van (Turkey). A voucher specimen was deposited in the VANF Herbarium. The samples for anatomical studies were preserved in 70% alcohol. The transverse and surface sections were cutted by hand with razor blade in microscopic preparation form. The chloral hydrate solution was used in microscopic examinations.

Result and Discussion: The basal and cauline leaves are dorsiventral and contain cover and glandular hairs. The main vein protrudes outward in the midrib of the both leaves. Different the basal leaf, the cauline leaf contains more glandular hairs on the upper surface and cover hairs on the lower surface. In both leaves, ranunculaceae type stomata were observed in the upper and lower epidermis. The simple arc-shaped petiole includes of numerous separate bundles embedded in the parenchymatous cells. The epidermal layer consist of numerous cover and glandular hairs.
