Abstract

This study was performed to determine karyological and morphological variability within and between populations of Bassia hirsuta in Bulgaria and to reveal their ecological preferences and detailed morphological characteristics. The studied Bulgarian B. hirsuta populations have diploid chromosome number 2n=18. The interpopulation variability which could be due to differences in ecological conditions is dominant. Vegetative traits are more variable than generative ones. The least variable are those that characterize the seed and could be used as highest value traits. The data given in the present study are supplementary to the data given about the species in Flora of the People’s Republic of Bulgaria and can be used both for correct identifications of the specimens and for getting familiar with species characteristics.

Bassia hirsuta (L.)’nın Bulgaristan Populasyonlarındaki Karyolojik ve Morfolojik Varyasyonlar

Abstract

Bassia hirsuta’nın Bulgaristan’daki populasyonlarındaki karyolojik ve morfolojik varyasyonu belirlemek ve populasyonların ekolojik tercihlerini ve detaylı morfolojik karakterlerini ortaya koymak amacıyla yapılmıştır. Çalışmada kullanılan B. hirsuta’nın Bulgaristan populasyonlarındaki diploid kromozom sayısı 2n=18’dir. Ekolojik şartlara bağlı olabilen populasyonlar arası varyasyon baskın durumdadır. Vejetatif özellikler, generatif özelliklere göre çok daha fazla varyasyon göstermektedir. En az varyasyon gösteren özellikler tohumla ilgili olanlardır ve önem dereceleri yüksek özellikler olarak kullanılabilirler. Bu çalışmada elde edilen bulgular, B. hirsute ile ilgili olarak “Flora of the People’s Republic of Bulgaria”da verilen bilgileri tamamlayıcı niteliktedir ve hem örneklerin doğru bir şekilde teşhis edilmeleri hem de türün özelliklerinin daha yakından tanınması amacıyla kullanılabilir
