    (Elsevier, 2009) Gurbuz, Bilal; Arslan, Neset; Khawar, Khalid Mahmood; Ipek, Arif; Sarihan, Ercument Osman; Ozcan, Sebahattin; Parmaksiz, Iskender
    Sternbergia candida is an important endemic bulbous plant with beautiful white flowers. It grows on the rock slopes of Baba mountains under Lebanon Cedars in the Mugla province of Turkey with Mediterranean climate. The plant is vulnerable and endangered due to illegal collection for local and foreign flower industry. Fast developing tourism industry and rapid urbanization has also shown negative implications on its population. The study reports three years successful adaptation results of S. candida in the continental climate of Ankara in the Central Anatolia. Four groups of bulbs based on diameter (>2.45, 2.15-2.44, 1.85-2.14 and <1.84 cm) were collected from its natural habitat during March, April and May 1998 and were evaluated for frequency (%) of emergence, mean number of leaves per plant, mean plant height, frequency (%) of flowering, frequency (%) of fruit setting. mean number of bulbs per plant, and mean diameter (cm) of regenerated bulbs. All categories of bulbs could be multiplied and adapted successfully with variable frequency of fruit setting. However, the highest fruit set was recorded from 2.15-2.44 cm April collected bulbs. This indicated that the bulb diameter and collection time had clear implications on multiplication, propagation and adaptation of the plant. (C) 2009 Elsevier B.V. All rights reserved.

    Evaluation of selected poppy (Papaver somniferum L.) lines by their morphine and other alkaloids contents
    (Springer, 2008) Guemuescue, Ahmet; Arslan, Neset; Sarihan, Ercument Osman
    The alkaloid analysis was performed in the laboratory of the alkaloid factory located at Bolvadin province of Turkey in 2000 on selected 99 poppy lines, which were selected with respect to their morphological and agronomic characteristics from around 1,000 poppy lines provided by Agriculture faculty, Ankara University. Our results showed that the ratio of the alkaloids, morphine, thebaine, codeine, papaverine and noscapine ranged from 0.110 to 1.140%, 0.005 to 0.134%, 0.005 to 0.27%, 0.001 to 0.440% and 0.006 to 0.418%, respectively, in the selected 99 poppy lines. According to their alkaloid content, 15 lines had significantly higher morphine, three lines had higher noscapine, and one line had higher papaverine levels.
