Abstract

In this study, it was aimed to test the seed viability of Alkanna orientalis and endemic Alkanna sieheana species rich in Alkannin/Shikonin (A/S) and to determine the germination percentage and callus regeneration suitable for in vitro A/S production. The viability rates of seeds collected from nature were determined by the tetrazolium method.The germination rates of the seeds of both species were tested with three different applications (on filter paper, MS nutrient medium with agar, in peat). The seed coats of both species were removed, and their embryos were cultivated in Murashige and Skoog (MS) media containing plant growth regulators in various proportions. The viability rates of the seeds were found at 98.3% for A. orientalisand 96.0% for A. sieheana. Germination rates were determined only on filter paper as 8.3% for A. orientalis and 5.0% for A. sieheana, no germination was observed in other applications. The highest zygotic shoot and root formation rate were obtained from A. orientaliswith 91.6% and 40.3%, respectively. But, the highest callus formation rate was observed on A. siehenea with 75.0%. As a result, it was determined that although the viability rates were high in both species, the germination rates were low, but in vitroreproducibility was possible.

Özet

Bu çalışmada, Alkanin/Şikonin (A/Ş) bakımından zengin olan Alkanna orientalis ve endemik Alkanna sieheanatürlerinin tohum canlılığının test edilmesi, çimlenme yüzdesinin ve in vitroA/Ş üretimine uygun kallus rejenerasyonunun belirlenmesi amaçlanmıştır. Doğadan toplanan tohumların canlılık oranları tetrazolium yöntemi ile belirlenmiştir. Her iki türe ait tohumların çimlendirmeleri üç farklı (kurutma kâğıt arasında, agarlı MS besin ortamında, torf içerisinde) uygulama ile testi edilmiştir. Her iki türün tohumların kabukları çıkartılarak çeşitli oranlarda bitki büyüme düzenleyicileri içeren Murashige ve Skoog (MS) ortamında kültüre alınmıştır. Tohumların canlılık oranları A. orientalisiçin % 98.3 ve A. sieheanaiçin ise % 96.0 olarak belirlenmiştir. Çimlenme oranları sadece filtre kağıdı arasında A. orientalis türü % 8.3 ve A. sieheanaiçin % 5.0 olarak tespit edilmiş, diğer uygulamalarda çimlenme gözlenmemiştir. In vitrouygulamalarda, en yüksek zigotik sürgün ve kök oluşum oranı sırasıyla % 91.6 ve % 40.3 ile A. orientalistüründe gözlenmiştir. Fakat en yüksek kallus oluşum oranı ise % 75.0 ile A. sieheanatüründe tespit edilmiştir. Sonuç olarak, her iki türünde canlılık oranlarının yüksek olmasına rağmen çimlenme oranlarının düşük, fakatin vitroüretilebilirliğinin ise mümkün olduğu tespit edilmiştir.
