In vitro propagation of native Ornithogalum species in West Mediterrenean region of Turkey

Ornithogalum is a popular genus especially, as an ornamental plant. In this study, eight native Ornithogalum species grown in West Mediterrenean Region of Turkey were cultured on MS media supplemented with combinations of BAP (1.0, 2.0, 4.0 mg L -1 ) and NAA (0.25, 0.50 mg L -1 ). The results indicated that the highest rate of proliferation was induced on Murashige and Skoog (MS) to which 4 mg L -1 BAP + 0.5 mg L -1 NAA (4.97 bulblets/explant) while the lowest rate of bulblet proliferation was obtained in 2 mg L -1 BAP + 0.25 mg L -1 NAA (2.27 bulblets/explant). Ornithogalum umbellatum showed the highest bulblet regeneration within the species. The regenerated bulblets were transferred into plastic viols containing mixture of peat moss and perlite (1:1) after 5 months.

DÜNYADA VE TÜRKİYE’DE ÇİÇEK SOĞANLARI SEKTÖRÜNÜN DURUMU

Cicek soganlari, Dunya’nin bazi ulkelerinde ve Turkiye’de ekonomiye sagladigi katki bakimindan sus bitkileri icerisinde ayri bir oneme sahiptir. Ancak ulkemizde ekonomiye saglanan bu katkinin buyuk bir kismi dogal cicek soganlarindan karsilanmakta ve bunlarin da buyuk bir cogunlugu dogadan sokulmektedir. Turkiye, diger bitkiler yonunden oldugu kadar cicek soganlari bakimindan da oldukca zengin olup yaklasik 700 adet soganli, yumrulu ve rizomlu turun anavatanidir. Uzun yillardan beri dogadan sokulen cicek soganlari, park ve bahce sus bitkisi, islah materyali veya tibbi bitki olarak degerlendirmek uzere cesitli ulkelere ihrac edilmektedir. Turkiye disariya cicek sogani ihrac eden tek ulke olmamakla birlikte dunya cicek sogani ihracatinda ilk siralarda yer almaktadir.
