    Adaptation of endemic mediterranean Sternbergia candida Mathew Et T. Baytop in the continental climate of central anatolia
    (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.

    Effects of treating with auxin solutions on rooting of cuttings of sainfoin (Onobrychis viciifolia)
    (Tropical Grassland Soc Aust, 2010) Avci, Suleyman; Cocu, Sati; Aasim, Muhammad; Sancak, Cengiz; Ozcan, Sebahattin
    Sainfoin is a cross-pollinating plant and segregates when material is multiplied from seed during breeding programs. While the use of cuttings allows rapid and reliable multiplication of selected material for vegetative propagation, cuttings often do not root well. This study examined the root development of sainfoin cuttings after dipping in solutions containing 0, 25, 50, 100 and 200 mg/L indole-3-acetic acid (IAA), alpha-naphthalene acetic acid (NAA) and indole-3-butyric acid (IBA) for 8, 16 and 24 h. The hormones were dissolved in either liquid Murashige and Skoog (MS) medium or distilled water. While untreated cuttings produced virtually no roots, all auxin treatments stimulated rooting on some cuttings. Dipping treatments using liquid MS medium as the base for the auxin solution produced better root development than those using distilled water. IBA was less effective than IAA or NAA in stimulating root production on cuttings. Dipping cuttings in a solution of IAA at 100 mg/L for 8 h in liquid MS medium would seem to be adequate to produce satisfactory root development. Rooted plantlets were transferred to pots and grew successfully under greenhouse conditions.
