Abstract

Bu çalışmada nehir kenarında ve tuzlu bataklıklarda yayılış gösteren Tamarix tetrandra Pallas ex. Bieb. türünün yaprak ve gövde yapısı anatomik ve mikromorfolojik yönden incelenmiştir. Türe ait örnekler anatomik incelemeler için %70’lik alkol içerisinde stok örnek haline getirilmiştir. Mikromorfolojik incelemelerde herbaryum örnekleri kullanılmıştır. Yapılan incelemelerde anatomik ve mikromorfolojik yönden farklılıklar olduğu belirlenmiştir. Tuzlu bataklıkta yayılış gösteren örneklerde stomaların epidermise gömülü olduğu tespit edilmiştir. Ayrıca nehir kıyısında yayılış gösteren türlerde ise gövde epidermis hücre boyu, sklerenkima hücre çapları, kalburlu boru hücre çapları ve öz hücre çaplarının daha büyük olduğu saptanmıştır. Yapılan korelasyon analizinde tuzlu bataklıkta yayılış gösteren türlerde yaprak alt yüzey stoma en ile üst epidermis hücre en arasında ve gövde sklerenkima hücre çap ile üst epidermis hücre en arasında pozitif korelasyon gözlemlenmiştir. Yapılan incelemelerde tuzlu bataklıkta yayılış gösteren türlerin gövde ve yaprak yapılarında yoğun bir tuz birikimine rastlanmamıştır. Bu türlerde tuz alınımının engellendiği düşünülmektedir.

Comparative leaf and stem anatomy of Tamarix tetrandra (Tamaricaceae) species from different habitats

Abstract

In this study, the leaf and stem structure of Tamarix tetrandra Pallas ex. Bieb. species, which are distributed in riparian and salt marshes, were examined in terms of anatomical and micromorphological aspects. Specimens of the species have been preserved in 70% alcohol for anatomical study. Herbarium specimens were used for micromorphological studies. The studies showed that there were differences in anatomy and micromorphology. It was found that the stomata were embedded in the epidermis in the samples distributed in the salt marsh. In addition, stem epidermal cell length, sclerenchyma cell diameter, sieve tube cell diameter, and pith cell diameter were found to be greater in riparian species. In the correlation analysis, a positive correlation was observed between leaf lower surface stomata width and upper epidermis cell width, and between stem sclerenchymatic cell diameter and upper epidermis cell width in species distributed in salt marshes. The studies did not find intensive salt accumulation in the stem and leaf structures of the species that spread in the salt marsh. Salt uptake is thought to be inhibited in these species.
