Bazı Vasküler Bitkilerin Yaprak Damar Ağının Karşılaştırılması

Bu çalışmada 14 bitki türüne ait ve farklı morfolojik özellikleri olan yaprakların damar anatomileri karşılaştırmalı olarak incelenmiştir. Bitkilere ait örnekler Samsun ilinin çeşitli lokalitelerinden toplanmıştır. Örneklerden alınan taze yapraklar kurutularak stoklanmıştır. Stok yapraklara saydamlaştırma ve boyama işlemi uygulanarak damar yapıları analiz edilmiştir. Taksonların yapraklarında toplam yaprak çevresi ve alanı, damar ve boğum sayısı, toplam damar uzunluğu, toplam damar alanı, ortalama damar uzunluğu, ortalama damar genişliği, ortalama damar 2D, 3D yüzey alanları ve ortalama damar hacmi gibi karakterler açısından önemli farklılıklar tespit edilmiştir. Elde edilen bulgulara göre damarlanmanın morfometrik özellikleri saydamlaştırma ve boyama aşamaları dikkatli uygulandığında sistematik, fizyoloji ve ekoloji gibi birçok alanda yapılacak araştırmalara katkı sağlayacak güvenilir karakterler sunabilir.

Comparative Leaf Vein Architectures of Some Vascular Plants

In this research, the vein architecture of leaves belonging to 14 plant species having different morphological features were comparatively analyzed. Plant leaf samples were collected from various localities in Samsun province and were dried. The vein patterns were analyzed by applying a clearing and staining process to dried leaves. Significant differences were determined across the leaves of the studied species in terms of characters such as leaf perimeter and area, no of nodes and edges, total network length and total network area, mean length, mean width, mean 2D and 3D surface areas and mean volume of the edges. When the clearing and staining stages are applied carefully, the morphometric properties of the vascularization may provide reliable characters that will contribute to the research in many fields such as systematic, physiology and ecology.
