Biochemical and Pomological Characteristics of Hawthorn (Crataegus Spp.) Fruits Grown in Şemdinli, Hakkari
(Centenary University, 2016) Yaviç, A.; Taylan, A.; Balci, H.; Encu, T.
The present study was conducted in Şemdinli town of Hakkari province in 2013-2014. The pomological and chemical characteristics of hawthorn (Crataegus spp.) fruits with different colors were investigated. Fruit samples were taken from 39 hawthorn trees selected from the villages of Şemdinli. In pomological analyses, fruit weight, fruit height, fruit width, number of seeds, seed weight and flesh ratio were determined. In chemical analyses, soluble solids content, pH, titratable acidity and sugar contents were determined. The evaluated accessions had average fruit weights of between 2.16-4.89g and flesh ratios of between 77.86-85.99%. Of the investigated genotypes, 16 were identified as promising genotypes. The greatest fruit weight was observed in yellow A-4 genotype with 4.89 g and the least fruit weight was observed in red L-9 genotype with 2.16 g. While glucose and sucrose were the dominant sugars in yellow hawthorn fruits, glucose and fructose were dominant in black and red hawthorn fruits. Of 16 promising hawthorn accessions, 7 had “yellow” skin color, 5 had “red”, 3 had “black” and 1 had “white” skin color. Current findings provide quite significant outcomes for further breeding studies. © 2016, Centenary University. All rights reserved.
The Effect of Some Organic Acid and Plant-Derived Material Treatments on the Germination and Emergence of Lettuce
(Springer Netherlands, 2016) Arin, L.; Balci, H.
The research was carried out to investigate the effect of plant materials which are used as an alternative to the synthetic chemicals in organic farming (thyme, mint, basil and garlic oil, hot pepper, and neem tree seed extract) and some organic acids (salicylic and jasmonic acid) on the germination, emergence, and seedling characteristics in lettuce (Lactuca sativa L.) cv Arapsaçı. The seeds of lettuce treated with these materials were subjected to germination and emergence tests at temperature 20 ± 1 °C and 60 ± 5 % RH in autumn period. After that, all seeds (including untreated) were kept at 5 ± 1 °C and again checked for germination, emergence, and seedling characteristics in spring period. Thyme oil affected negatively the germination and emergence, and also, the infected seed ratio increased. Although the infection ratio was 1 % in untreated seeds, it was 7.8 % in the seeds treated with thyme oil. After the storing period, infection ratio of thyme oil was 8.5 % which was higher than other treatments. There was no significant effect of treatments on seedling characteristics. © 2015, Springer Science+Business Media Dordrecht.
A Study on Determining the Causes of Preference of Students in Department of Plant and Animal Production of Gevaş and Başkale Vocational Schools
(Centenary University, 2017) Çelikyürek, H.; Gökdal, Ö.; Balci, H.
The aim of this study was to reveal the reasons of preference of the students who study in Plant and Animal Production departments at Gevaş and Başkale Vocational High Schools, Yüzüncü Yıl University and to be a light on the plans to be made in relation to vocational education. The questionnaire survey was conducted with the method of “under observation” on 178 (50 students from Başkale Vocational High School, 128 students from Gevaş Vocational High School) students in 2017. According to the results, it is understood that 24.16% of the students who participated in the survey has preferred the program because they are interested in the related programs. 13.48% of them have aimed the faculty departments by transit exam. After the graduation, 49.44% and 17.98% of the students have aimed “studying a faculty department” and “establishing their own business”, respectively. Following these, 16.29% of the students have stated the aim of “working in a governmental institution related to their profession”. Among the target variables after graduation from the school, girls generally have wanted to study faculty departments, while boys have not had a high expectation after graduation (p <0.05). As a result of Chi-square analysis, the relationship between gender of the students and the reasons for preference of the program was found statistically significant (p <0.01). According to the results, a significant amount of the students is targeted to continue their studies in faculty departments. This situation should be questioned in terms of training objectives of vocational schools. © 2017, Centenary University. All rights reserved.
