2020
Ahmet Yusuf Şengül | Turgay Şengül | Şenol Çelik
The study aims to investigate the effects of changes in body weight of Japanese quails (Coturnix coturnix japanica) on some external and internal quality characteristics of their eggs and the correlations between them. In the experiment, totally 30 female quails raised in individual cages and 180 eggs obtained from them were utilized. According to the body weight, 30 quails were divided into 5 different groups and body weight averages were 238.0, 216.0, 202.3, 191.3 and 174.0 g for 1st, 2nd, 3rd, 4th and 5th groups, respectively. The examined eggs were individually collected from the quails and evaluated under live weight groups of quails. According to the results, egg weight, shell weight, shell thickness, shell ratio, albumen weight, albumen ratio, yolk weight, yolk diameter, and yolk ratio were significantly affected from body weight. There were found significant positive correlations of live weight with egg weight, albumen weight and yolk weight (respectively, 0.28, 0.24, and 0.25) and significant positive correlations with shape index and shell weight (respectively, 0.17 and 0.15).

In wheat cultivation, sowing frequency is one of the crucial agronomic applications affecting grain yield. The aim of the research was to determine the effects of application of different sowing frequency (350, 500, 650 and 800 seeds m-2) for bread wheat cultivars (Alpu 01, Atay 85, Bezostaja 1, Harmankaya 99, Sönmez 01 and Sultan 95) on yield and yield components. Trials was carried out in Transitional Zone Agricultural Research Institute Eskişehir central campus fields during at 2012-13 and 2013-14 crop seasons in irrigated and rain fed conditions with 3 replications in randomized complete blocks design. In this study, the factors such as grain yield, number of spike per square meter, spike length, number of grain per spike, weight of grain per spike and harvest index were examined in terms of sowing frequency applications and cultivars in both conditions. As a result, the maximum grain yield was obtained from 650 seeds m-2 in rainfed conditions and this value was obtained from the application 500 seeds m-2 in irrigated conditions. Harmankaya_99 variety reached the highest values in terms of grain yield in both conditions and followed this by Alpu01 variety. In both conditions spike length, number of grain per spike, weight of grain per spike and harvest index parameters decreased inversely with increasing sowing frequency, while the number of spike number per square meter increased in direct proportion to increased sowing frequency. In rainfed conditions while there was a positive correlation between the grain yield with number of spike per square meter and harvest index, there was negative correlation among grain yield with spike length, number of grain per spike and weight of grain per spike. There was found significant positive correlation between grain yield with spike length and harvest index in irrigated conditions.

Seydi Aydoğan | Mehmet Şahin | Aysun Göçmen Akçacık | Seyfi Taner
This research was conducted to determine grain yield and some quality traits of 18 bread wheat varieties in dry conditions and location in the center of Konya in 2009-2010 growing seasons. Grain yield and some quality characteristics (protein content, zeleny sedimentation, gluten index, alveograph energy value, alveograph P/L, mixograph development time, mixograph peak height, and mixograph softening value and mixograph total area) were examined. According to the results including means ranged between; grain yield 331.85-749.05 kg/da, Protein content 12.62-15.23%, gluten index value of 41.81-98.19%, zeleny sedimentation value 27.00-51.50 ml, alveograph energy 59.70-235.43 10-4 Joules alveograph P/L 0.38 to 1.29, micsograph development time 1.44-4.95 min., mixograph peak height, 42.46-60.67%, mixograph right peak slope 10.13-45.52%, mixograph total area 239.12-322.28% Tq*dak, was found. The experiment has been found significant correlations between traits.
Mostrar más [+] Menos [-]Determination of Total Phenolic Content and Antioxidant Activities of Different Sesame (Sesamum indicum L.) Genotypes
2020
Cemal Kurt | Burçak Uçar | Murat Reis Akkaya
Due to a better understanding of its positive effects on nutrition and health, consumer demands for sesame seeds and products have increased steadily in recent years. The aim of the study is to determine the total phenolic content belonging to 17 different sesame genotypes (with different seed color) and the antioxidant content by DPPH and ABTS methods. The total amount of phenolic substance varied between 1.99-6.81 mg GA/g, and the highest amount of phenolic content was obtained from the Libya genotype, while the lowest value was obtained from the Gaziantep-Oğuzeli genotype. While antioxidant activity values obtained according to DPPH method varied between 8.23 and 17.50 mg Trolox/g, antioxidant activity values obtained according to ABTS method ranged between 3.62 and 4.18 (mmol Trolox)/g. According to the correlation analysis, it was determined that there was a statistically significant and positive relationship between antioxidant capacities according to total phenolic content, DPPH and ABTS methods. However, no relation was found between the seed color and these properties.

Path analysis is determinate that relationships among variables by using correlation coefficient, partial correlation coefficient and path coefficient. In this study, direct and indirect effects of honey yield between brood rearing area, flight activity, pollen collection, nectar collection and cleaning power were examined with these coefficients. Data which taken from C.U. Faculty of Agriculture, Department of Animal Science, Beekeeping Business were used. In the end of this research, the effect of brood rearing area on honey yield was found significant. In the colonies, brood rearing area has the highest direct effect of honey yield. Nectar collection has the highest indirect effect.
