    Comparison between a wild population and cultivar of common vetch (Vicia sativa L., Fabaceae) on cytological and agronomic characteristics
    (Taylor & Francis Ltd, 2006) Celiktas, Nafiz; Can, Ersin; Hatipoglu, Rustu; Avci, Suleyman
    The aim of this study was to compare a wild population of common vetch (Vicia saliva L.) collected from the Serinyol district of Antakya in the east Mediterranean coastal region of Turkey with a cultivar of common vetch (V saliva 'Anadolu'), on somatic chromosome number and important agronomic attributes. Somatic chromosome counts from material collected from the wild population of Vicia saliva L. were consistently 2n = 10, while the cultivar had 2n = 12. There were no significant differences between wild and cultivated cytotypes in plant height, seed number or pod number, although the wild cytotype had significantly more branches, smaller seeds, higher hardseededness and lower germination rates.

    Effects of genotype and 2,4,5-T concentrations on callus induction, shoot formation and plant regeneration from young inflorescences in orchardgrass (Dactylis glomerata L.)
    (Wfl Publ, 2013) Atis, Ibrahim; Can, Ersin; Celiktas, Nafiz; Hatipoglu, Rustu
    This study was carried out to determine the effects of MS medium supplemented with 2, 4, 6 and 8 mg l(-1) of 2,4,5-T (2,4,5-trichlorophenoxyacetic acid) on young inflorescences of five ecotypes of orchardgrass (Dactylis glomerata L.). The results showed that there was a significant interaction between ecotypes and 2,4,5-T concentrations in all characteristics studied. Depending on the ecotypes, rate of callus induction (%), rate of shoot formation (%), callus weight (mg/per Petri dish) and number of regenerates per inflorescence segment varied and ranged 6.3-37.5%, 7.8-51.6%, 13.1-115.4 mg and 0.3-1.1, respectively. Rates of callus induction and shoot formation as well as callus weight were also significantly influenced by the 2,4,5-T concentrations. The explants cultured on MS medium containing 4 mg(-1) of 2,4,5-T showed highest callus induction rate of 53.8 % with callus weight of 170.4 mg/Petri dish and 1.6 shoots per explant. It was concluded that best regeneration from young inflorescence explant of orchardgrass (D. glomerata) could be obtained on MS medium containing 4 mg l(-1) of 2,4,5-T and the developed protocol will help in easy multiplication of orchard grass in future breeding studies.

    Effects of seeding rate on forage yield and quality of vetch (Vicia sativa L.) - triticale (Triticosecale Wittm.) mixtures under east mediterranean rainfed conditions
    (Academic Journals, 2009) Kokten, Kagan; Toklu, Faruk; Atis, Ibrahim; Hatipoglu, Rustu
    This study was carried to determine the best seed mixture of vetch and triticale for East Mediterranean rainfed conditions of Turkey. The experiments were conducted in two locations, Adana and Kozan, during the years of 2003 - 2005. The field trials were arranged in a randomised block design with three replications. In the research, pure stands of vetch and triticale and their seed mixtures (80% vetch + 20% triticale, 60% vetch + 40% triticale, 40% vetch + 60% triticale, 20% vetch + 80% triticale) were studied. Crude protein concentrations, hay and crude protein yields of pure stands and the mixtures and the percentage of vetch in the dry matter yield were determined. In addition to these, relative yield total (RYT) values were calculated for the mixtures. The study showed that the characters studied were significantly influenced by years, locations and mixtures. According to the averaged values of two years, the seed mixture containing 20% vetch and 80% triticale gave highest dry matter yield with an average vetch content of 23.5% under Adana conditions, while the seed mixture of 40% Vetch + 60% triticale gave the highest dry matter yield with an average vetch content of 10% under Kozan conditions. RYT values for the mentioned mixtures were 1.12 and 1.20, respectively. It was concluded that the above mixtures of vetch and triticale could be recommended for the locations in Adana and Kozan, respectively.

    Plant density and mixture ratio effects on the competition between common vetch and wheat
    (2012) Atis, Ibrahim; Kokten, Kagan; Hatipoglu, Rustu; Yilmaz, Saban; Atak, Mehmet; Can, Ersin
    Mixtures of annual forage legumes with winter small grains for forage are practiced traditionally in the Mediterranean countries. The aim of the present study was to investigate the effects of variable seed mixture rates and different plant densities on the forage yield. The study also investigated the competition effects among mixture partners in the mixture of common vetch (Vicia sativa L.) and wheat (Triticum aestivium L.). Field trials were conducted at two locations (L1, Hatay and L2, Adana) during the 2008-09 and 2009-10 growing seasons. Three plant densities (200, 400, 600 plants m-2) and five seed mixture ratios (100 % V, 75% V + 25% W, 50% V + 50% W, 25% V + 75% W, 100 % W) of common vetch (V) and wheat (W) were used. The results of the study showed that increased plant density in the mixture resulted in increased dry matter yield per unit area. In addition, increased seed ratio of wheat in the mixture caused increased dry matter yield per unit area. Also, elevated dry matter yield resulted in increased crude protein yield. Land equivalent ratio (LER), aggressivity (A) and competitive ratio (CR) indexes showed that common vetch was the dominant species in all common vetch-wheat mixtures.

    Somatic embryogenesis, callus production, and plantlet growth in sainfoin (Onobrychis viciifolia Scop.)
    (Rsnz Publishing, 2006) Celiktas, Nafiz; Can, Ersin; Hatipoglu, Rustu; Avci, Suleyman
    Plant parts (internode segments, young leaves, apical-axillary meristems, petioles and immature inflorescences) isolated from the fresh, full-leaved and juicy sainfoin (Onobrychis viciifolia Scop.) were used as explants in this study. The explants were cultured on B5 medium with 5.4 mu M or 10.7 mu M NAA combined with 0, 0.9, 1.4, or 2.3 mu M of kinetin and 0, 0.9, 1.3, or 2.2 mu M of BAP to determine the effects of explant types and medium compositions on the callus induction and plant regeneration. Somatic embryogenesis and organogenesis, as well as direct shoot regeneration from the explants, were observed depending on the explant types and medium composition. The effect of the phytohormone type and concentration on the callus induction rate was under explant dependency. The highest frequency of shoot regeneration was achieved from apical-axillary meristems on B5 medium with 10.7 mu MNAA and 2.3 mu M kinetin.
