Lilium candidum L. is a species which grows in the South

This study is a part of a M.S. thesis. 2Mugla University, Faculty of Science and Arts, Department of Biology, 48170 Muğla, Turkey.Abstract -The effects of high doses of extracts of Urginea maritima bulbs which can be used as bio-pesticides were investigated with the Allium test method. The bulbs of Allium cepa were rooted in solutions including 8%, 10%, 12%, 14%, 16% and 100% (v/v) U. maritima extracts for 48, 72 and 144 hours. Moreover, the bulbs were rooted in a solution including 2% of a chemical pesticide (Vydate ® ) and in tap water (as control). A. cepa root tip meristem cells were prepared according to Feulgen squash procedure and the chromosomal aberrations and cell anomalies were determined. The data were evaluated with statistical analyses. Chromosome aberrations occurring in all solutions including U. maritima extract and vydate solution were found to be signifi cantly related to the increasing dose and period of the treatment. Moreover, a statistically signifi cant decrease was observed in the mitotic index (MI) when compared to the control. It was found that even the high doses of U. maritima extract are less genotoxic and cytotoxic than vydate.

Lilium candidum bulb scales were cultured on MS containing different doses and combinations of NAA, BA, Kn and 2iP. Maximum bulblet formation was 88.2% in MS supplemented with 0.1 mg/l NAA + 0.01 mg/l BA and the average number of bulblets per explant was 2.9.

Lilium candidum is one of the important commercial crop worldwide. In this study, a protocol for micropropagation of Lilium candidum was developed the effect of some antibiotic and fungicide applications and also the effect of the light. In experiments, bulb scales of Lilium candidum L. were used. The plant material was sterilized superficially and it was dipped in solutions which contain antibiotic and fungicide 30 minutes was cut into pieces and cultured in Murashige and Skoog (1962) medium supplemented with 0.1 mg/L NAA + 0.01 mg/L BA, 30 mg/L sucrose and 8 mg/L agar. The application of antibiotic and fungicide was the application of Streptomycin + Penicillin, Streptomycin + Benomyl and Benomyl + Nystatin in every two different doses. Bulb scales were cutting into lateral as 5-10 mm pieces. The explants were cultured 16 hrs light -8 hrs dark photoperiodic condition; the light was 1600 lux, and also were cultured in completely darkness condition in the same applications. Culture room temperature was between 19° and 22 °C. Bulblet formation (%) was observed in photoperiodic condition higher than darkness one. In the Benomyl + Nystatin solution bulb formation (%) was the highest (97.4%). In addition the best application was obtained Benomyl + Nystatin solution both in respect of sterilization and the point of view the number of the bulblets. Lilium candidum L.'nin MİKROÇOĞALTIMINDA BAZI ANTİBİYOTİK ve FUNGUSİT UYGULAMALARININ ETKİSİÖz Bu çalışmada, dünya çapında ticari öneme sahip olan Lilium candidum L.'nin mikroçoğaltımında bazı antibiyotik ve fungusit uygulamalarının in vitro'da ki etkisi, uygun sterilizasyon ve ışığın etkisi araştırılmıştır. Denemelerde temel MS (1962) ortamı kullanılmış, ortama 0.1 mg l/L NAA+ 0.01 mg l/ L BA, 30 g /L şeker ve 8 g /L agar ilavesi yapılmıştır. Bitki materyali (soğan pulları) yüzeysel sterilizasyonu takiben antibiyotik ve fungusit içeren solusyonlarda 30 dk bekletildikten sonra parçalara ayrılarak kültüre alınmıştır. Antibiyotik ve fungusit uygulamaları: iki farklı dozda Streptomycin + Penicilin uygulamaları, iki farklı dozda Streptomycin + Benomyl uygulamaları ve iki farklı dozda Benomyl + Nystatin uygulamalarıdır. Lilium candidum soğan pulları 5-10 mm boyutunda enine parçalara ayrılarak kültüre alınmıştır. Karanlık ve fotoperiyodik koşulda (16 saat aydınlık-8 saat karanlık) kültüre alınan eksplantlarda % soğancık oluşumunun, fotoperiyodik koşulda karanlığa göre daha yüksek olduğu gözlenmiştir. Ayrıca yüzeysel sterilizasyondan sonra yapılan uygulamalarda hem sterilizasyon yönünden hem de eksplant başına elde edilen soğancık sayısı bakımından en olumlu uygulamanın Benomyl + Nystatin solusyonlarının olduğu belirlenmiştir.
