    Effects of drip irrigation management and different soilless culture on yield and quality of tomato grown in a plastic house
    (2006) Sezen, S. Metin; Celikel, Gulendam; Yazar, Attila; Mendi, Yesim Yalcin; Sahinler, Suat; Tekin, Servet; Gencel, Burçin
    This study was carried out to determine the most suitable irrigation scheduling of fresh market tomato (Fantastic-144) grown on volcanic ash, peat and their mixture (1:1) under Plastic house conditions at Alata Horticultural Research Institute in the Mediterranean Region of Turkey in 1998. The quality and yield response of Fantastic-144 to trickle irrigation was also investigated. Four different irrigation levels (WL1 = 75%, WL2 = 100%, WL3 = 125% and WL4 = 150% of Class A Pan evaporation) and two irrigation frequencies (once and twice daily applications) were evaluated. Highest yield and fruit number were obtained from the ash+peat (1:1) with irrigation once a day at WL4 and ash+peat (1:1) with twice a day watering at WL3 and WL4 irrigation levels. Soluble solids of tomato fruit decreased with increasing available water. The highest WUE value of 67.5 kg m-3 was obtained from WL1 with peat+ash (1:1). WUE decreased in all treatments as the amount of irrigation water increased. © 2006 Asian Network for Scientific Information.

    Regeneration and Histological Analysis of Regeneration in Bottle Gourd (Lagenaria siceraria (Molina) Stand.)
    (Tubitak Scientific & Technological Research Council Turkey, 2009) Mendi, Yesim Yalcin; Ipek, Muzaffer; Buzkan, Nihal; Kancar, Yildiz Aka; Curuk, Sebahattin
    Two different types of explant (proximal and flamingo-bill) from Emphasis seedlings, a hybrid cultivar of bottle gourd (Lagenaria siceraria (Molina) Stand.). germinated under dark and light conditions were cultured on 9 regeneration MS media containing various combinations of BA (0, 1.0. and 2.0 mg l(-1)) and IAA (0, 0.25, and 0.5 mg l(-1)). Comparison of the explant types showed that the flamingo-bill type explant had better shoot formation than did the proximal explant. The MS medium containing 1 mg l(-1) of BA was optimal for shoot formation capacity when flamingo-bill type explants germinated in the dark (44%) and light (36%) were used. Histological analysis showed that explant cell division began after 3 days in regeneration medium and formation of primordium was observed in the tissues in culture between days 5 and 7. Differentiation of meristimatic structures was first observed after 9 days and development completed after 9-12 days in the culture.
