Rindera cetineri Yıldırım (Boraginaceae) üzerinde anatomik, mikromorfolojik ve karyolojik araştırmalar

Bu çalışmada Denizli’de yayılış gösteren lokal endemik Rindera cetineri Yıldırım türünün anatomik, mikromorfolojik ve karyolojik özellikleri incelenmiştir. Anatomik çalışmalarda kök ve gövde ölçümleri için enine kesitler, yaprak (taban ve gövde yaprağı) ölçümleri için enine ve yüzeysel kesitler alınmıştır. Yapraklardan alınan yüzeysel kesitlerde alt ve üst yüzeyde bulunan stoma ve epidermis hücreleri sayılarak stoma indeksi hesaplanmıştır. Mikromorfolojik çalışmalarda ise polen tipi ve yüzey ornamentasyonu ile tohum şekli ve yüzey ornamentasyonu belirlenmiştir. R. cetineri türünün polen tipi 6- heterokolpat olup polen şekli prolat-sferoidal, subprolat ve yüzey ornamentasyonu ise mikrogranulattır. Karyolojik çalışmalar sonucunda, R. cetineri türünün somatik kromozom sayısı 2n=24 olarak belirlenmiştir.

Anatomical, micromorphological and karyological studies on Rindera cetineri Yıldırım (Boraginaceae)

In this study, the anatomical, micromorphological and karyological features of Rindera cetineri Yıldırım (Boraginaceae), an endemic species in Denizli, were investigated. In anatomical studies, cross sections for root and stem measurements, and cross and superficial sections for leaf measurements (base and stem leaf) were taken. The stomatal index was calculated by counting the stomata and epidermis cells on the upper and lower surfaces of the superficial sections taken from the leaves. In micromorphological studies, pollen type and surface ornamentation, seed shape, and surface ornamentation were determined. The pollen type of R. cetineri is 6-heterocolpate, the pollen shape is prolate-spheroidal, subprolate and the surface ornamentation is microgranulate. As a result of the karyological study, the somatic chromosome number of R. cetineri was determined as 2n=24.
