Abstract

In this study, the chromosome numbers and morphology of the populations of Galanthus fosteri Baker var. fosteri and Galanthus fosteri var. antepensis Zeybek and Sauer distrubuting in various geographic regions of Turkey have been investigated. In the karyological investigations, the structural polymorphizm SAT-chromosome have been established in the chromosomes of G. fosteri var. fosteri and G. fosteri var. antepensis. Although the diploid chromosome numbers 2n=24 of these varieties are similar, the chromosome morphology of their are significantly different

Galanthus fosteri Baker Amaryllidaceae ’’’’nin iki varyetesi üzerinde karyolojik bir araştırma

Abstract

Bu çalışmada, Türkiye’nin farklı coğrafik bölgelerinde yayılış gösteren Galanthus fosteri Baker var. fosteri and Galanthus fosteri var. antepensis Zeybek and Sauer populasyonlarının kromozom sayıları ve morfolojisi incelenmiştir. Karyolojik incelemelerde, G. fosteri var. fosteri and G. fosteri var. antepensis kromozomlarında yapısal polimorfizm SAT-kromozom tespit edilmiştir. Bu varyetelerin diploid kromozom sayısı 2n=24 aynı olmasına rağmen, onların kromozom morfolojileri önemli derecede farklıdır
