    EFFECTS OF CADMIUM AND HIGH TEMPERATURE ON CHLOROPHYLL AND MINERAL NUTRIENT CONTENTS IN Triticum aestivum L. SEEDLINGS
    (Aloki Applied Ecological Research And Forensic Inst Ltd, 2021) Ergun, N.; Karanlik, S.; Tiryakioglu, M.
    Wheat plays a particularly important role in the human diet. Environmental stresses negatively affect wheat development and yield. This study was conducted to determine the effects of high temperature-cadmium interactions on total chlorophyll content, chlorophyll a / chlorophyll b ratio as well as cadmium and mineral nutrient contents (potassium, magnesium, zinc, calcium) in wheat seedlings. Seedlings belong to two varieties of bread wheat (Triticum aestivum L.) named Dagdas and ES-14 were treated with different concentrations of cadmium (Cd) (0, 15, 75 ppm), under different (24/16 degrees C and 40/30 degrees C daytime/night-time) temperature conditions. The total chlorophyll increased in the Dagdas and decreased in the ES-14 in response to the high-temperature treatment (40/30 degrees C). Cadmium caused a decrease in the Chlorophyll a/b ratio in varieties at high-temperature conditions. The accumulation of cadmium and uptake of other minerals in shoots differed depending on the wheat variety and cadmium-temperature interaction. Cadmium accumulation in shoots increased in response to the cadmium treatments. Cadmium accumulation decreased at the 40/30 degrees C temperature compared to that at 24/16 degrees C temperature. Calcium accumulation increased in shoots as a response to high temperature in both varieties. In both varieties, the potassium content increased in response to cadmium (15 mu M) and high temperature.

    Effects of Composted Municipal Solid Wastes on Phenology and Yield Characteristics of Wheat (Triticum aestivum L.) in Eastern Mediterranean Region
    (Asian Journal Of Chemistry, 2009) Sener, O.; Aydin, M.; Tiryakioglu, M.
    This study was carried out to evaluate the effects of compost application produced from municipal solid wastes on growth and yield of wheat under semi-arid Mediterranean conditions. The compost was produced from mainly house-originated solid wastes, bay leaves and farmyard manure mixture in a ratio of 7.5:1.5:1.0, respectively. The treatments were: chemical fertilizer (160 kg N ha(-1) and 80 kg P2O5 ha(-1)); 20, 40, 60 and 80 tons compost ha(-1); 80 tons animal manure ha(-1) and control without treatments. The experimental design was randomized blocks with three replications. According to the results of a three-year experiment, application of 20 tons of compost ha(-1) appeared to be the most suitable treatment for satisfied yield. Moreover, some positive effects of the compost application on growth parameters of wheat were observed.

    GENOTYPE BY ENVIRONMENT INTERACTION AND GGE BIPLOT ANALYSES IN DURUM WHEAT UNDER WATERLOGGING STRESS
    (Pakistan Agricultural Scientists Forum, 2023) Tiryakioglu, M.; Akcali, C. T.; Sahin, C. B.; Karanlik, S.; Ergun, N.
    Waterlogging is one of the major limitations that reduce productivity in wheat all over the world. The present study aimed to identify waterlogging-tolerance in durum wheat genotypes. Thirty-two durum wheat genotypes were screened under aerobic and anaerobic conditions using randomized complete block design with three replications. High-purity nitrogen gas was used to provide and maintain waterlogging stress, while the control group was aerated with the air. Growth and physiological parameters i.e., shoot dry weight gain, root dry weight gain, total dry biomass weight gain, plant leaf area, dry leaf weight, specific leaf weight, chlorophyll content, carotenoid content, and their tolerance indices were determined. Durum wheat seedlings grown under anaerobic conditions had significantly lower shoot dry weight, total dry biomass weight, specific leaf weight, chlorophyll a, and chlorophyll a + b content. Results further revealed that the tolerance indices varied depending on wheat cultivars for the investigated parameters. Harran 95 under aerobic condition and Eminbey under anaerobic condition had the highest tolerance indices for shoot dry weight gain and total dry biomass weight gain. However, Kiziltan 91 had the highest tolerance indices for root dry weight gain under these two conditions. For these reasons, Kiziltan 91 came to forefront position with its stability and could be used in durum wheat breeding. For identifying the correlation of tolerance index with seed yield and potential genotypes to be used as a selection criterion, further studies are needed under field conditions.
