Abstract

Conservation and management of threatened species in many studies to be carried out on the basis, in the understanding of the characteristics associated with reproductive biology and attention was drawn to the study. Germination and seedling placement of these properties are the most vulnerable in the life cycle of plants and seed germination of endemic species particularly better understanding of requirements and capacity is essential for conservation and management of biodiversity. The aim of this study, chasmophytic endemic of Campanula tomentosa and C. vardariana species, ex-situ cultivate and strengthening of natural populations. For this purpose in our study, the determination of germination characteristics of these species as well as different concentrations of photoperiod and the germination percentage and mean germination time of GA3 were investigated. According to the results of Analysis of Variance, Campanula tomentosa and C. vardariana seeds of different photoperiod and alternate temperature, 20 °C continuous dark and different concentrations of GA3 of the average germination percentage effect statistically insignificant p>0,05 when determining this application, the average germination time effect on the statistically significant were determined p

Kazmofit endemik Campanula tomentosa ve Campanula vardariana üzerinde tohum çimlendirme çalışmaları

Abstract

Tehdit altındaki türlerin korunması ve yönetilmesini temel alan birçok çalışmada üreme biyolojisi ile ilişkili özelliklerin anlaşılmasına ve araştırılmasına dikkat çekilmiştir. Bu özelliklerden çimlenme ve fide yerleşimi bitkilerin yaşam döngüsünde en hassas durumdur ve özellikle endemik türlerin tohum çimlenme gereksinimleri ve kapasitelerinin iyi anlaşılması, biyoçeşitliliğin korunması ve yönetimi için temeldir. Bu çalışmada kazmofitik endemik Campanula tomentosa ve C. vardariana türlerinin ex-situ yetiştirilmesi ve doğal populasyonlarının güçlendirilmesi amaçlanmıştır. Bu amaçla çalışmamızda bu türlerin çimlenme özelliklerinin yanısıra farklı fotoperiyotlarda ve konsantrasyonlarda GA3’ün çimlenme yüzdesine ve ortalama çimlenme süresine etkileri araştırılmıştır. Varyans analiz sonuçlarına göre, C. tomentosa ve C. vardariana’ya ait tohumların farklı fotoperyot p>0,05 , değişken sıcaklık, 20°C de sürekli karanlık ve farklı konsanrtasyonlarda GA3 uygulamalarının ortalama çimlenme yüzdesine etkisi istatiksel olarak anlamsız tespit edilirken, bu uygulamaların ortalama çimlenme süresi üzerine etkisi istatiksel olarak anlamlı olarak belirlenmiştir p
