Low temperature is one of the critical factors for determining agricultural production. Therefore, the main objective was to develop the durum wheat lines, which are tolerant to cold particularly in Central Anatolia. The recombinant inbred lines (RILs) (141) derived from F-6 progeny of durum wheat, developed from Kunduru-1149 (female parent) and Cham-1 (male parent) cross, were characterized in terms of their cold tolerance both in the field and under controlled (in growth chamber) conditions. A 0-9 scale was used for the visual evaluation of cold damage under field conditions, and a quantitative measure of photochemical efficiency (Fv/Fm = variable fluorescence/maximum fluorescence) method was used for the evaluation of cold damage under controlled conditions. Seventeen RILs displayed the scores within the range of 1-2.5 in 0-9 scale evaluation, while 41 RILs showed the scores equal to or higher than 0.70 approaching to optimal (similar to 0.83) in Fv/Fm evaluation. Some quality parameters tested and some gliadin fragments and random amplified polymorphic DNA loci showed meaningful correlations with the data of 0-9 scale and Fv/Fm ratios from lower to the medium level. The RILs considered as cold resistant; might have the potential to be used as parental lines to develop cold-resistant durum wheat varieties in the future durum wheat-breeding programmes.

Evaluation of salt tolerance in sto transformed Arabidopsis thaliana and Nicotiana tabacum plants Selçuk, Feyza; Yücel, Ayşe Meral; Department of Biology (2004) Salinity is one of the limiting factors of crop development. Together with causing water loss from plant tissues, salinity also leads to ion toxicity. Under salt stress, increase in Ca+2 concentration in cytosol can decrease the deleterious effects of stress. The binding of Ca+2 to calmodulin initiates a signaling cascade involving the activation of certain transcription factors like STO and STZ. This signal transduction pathway regulates transport of proteins that control net Na+ influx across the plasma m...
STATISTICAL PROCESS ANALYSIS IN BROILER FEED FORMULATION ALTI, M; OZILGEN, M (Wiley, 1994-09-01) Statistical analysis of broiler feed production was done with data obtained in an industrial plant in an attempt to characterise the causes of variations in feed composition. Analysis of the experimental data has shown that the feed conversion ratio (FCR) for broilers was between 1.8 and 2.5. This large range of observations were thought to be caused by the wide range of variations in the composition of the feeds. The major factor contributing to the variance of the feed compositions was the variance of the...
Photosystem II and cellular membrane stability evaluation in hexaploid wheat seedlings under salt stress conditions Ozalp, VC; Öktem, Hüseyin Avni; Naqvi, SMS; Yucel, M (Informa UK Limited, 2000-01-01) Salinity limits crop production in large areas of the world. The application of in vitro Photosystem II (PS-II) activity measurements to screen hexaploid wheat (Triticum aestivum, L.) genotypes for NaCl tolerance has been investigated by comparing their responses under stress and control (no added NaCl) conditions. One of the four cultivars used in the study was 'Kharchia' known for its high salt tolerance. Wheat seedlings were grown hydroponically in environmental chambers and treated with a range of NaCl ...
Simultaneous dissolution and uptake of nutrients in microalgal treatment of the secondarily treated digestate Ulgudur, Nilufer; Bayramoğlu, Tuba Hande; Demirer, Goksel N. (Elsevier BV, 2019-11-01) Anaerobic digestion processes result in large volumes of digestates which still require the development of elaborate and viable management options to improve the sustainability of these processes. Coupling of secondary anaerobic treatment with a microalgal nutrient removal process may serve benefits such as residual biogas and associated greenhouse gas capture from the digestate content, microalgal biomass build-up and its further valorization. This study investigated the applicability a microalgal nutrient...
Effects of trophic status, water level, and temperature on shallow lake metabolism and metabolic balance: A standardized pan-European mesocosm experiment Scharfenberger, Ulrike; Jeppesen, Erik; Beklioğlu, Meryem; Sondergaard, Martin; Angeler, David G.; Cakiroglu, Ayse Idil; Drakare, Stina; Hejzlar, Josef; Mandy, Aldoushy; Papastergiadou, Eva; Sorf, Michal; Stefanidis, Konstantinos; Tuvikene, Arvo; Zingel, Priit; Adrian, Rita (Wiley, 2019-03-01) Important drivers of gross primary production (GPP) and ecosystem respiration (ER) in lakes are temperature, nutrients, and light availability, which are predicted to be affected by climate change. Little is known about how these three factors jointly influence shallow lakes metabolism and metabolic status as net heterotrophic or autotrophic. We conducted a pan-European standardized mesocosm experiment covering a temperature gradient from Sweden to Greece to test the differential temperature sensitivity of ...
