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.
Effect of the Application of Root Cutting After Germination on the Seedling Growth in the Walnut Seeds Taken From Van Lake Basin
(Centenary University, 2016) Yaviç, A.; Doğan, A.; Kazankaya, A.; Encü, T.
This research was cunducted in production greenhouses of Yuzuncu Yıl University Agriculture Faculty Horticultural Crops Department during 2014-2015. Walnuts taken from various areas of Van Lake basin were used as research material. In order to determine the effects of the application of root cutting methods on walnut seedlings after germination three different applications were used (cutting of radicle from 5 cm, cutting of radicle from 7 cm and control). One third of the walnuts which were ripped from the rooting area after germination have been planted without cutting the radicle and planted back to the germination area. The research revealed that the seedlings from control group performed well in shoot growth while the seedlings from 7 cm radicle cut group gave better results in the parameters about root development. The research also indicated that the area that welnut seeds were taken affected the seedling performences. © 2016, Centenary University. All rights reserved.
Identification of Morphological and Pomological Characteristics of Iraq Pomegranate (Punica Granatum L.) Variety Salakhani and Comparing With Variety Zivzik
(Pamukkale University, 2019) Al-Jabbarı, K.H.; Pakyürek, M.; Yaviç, A.
In this study, morphological and pomological characteristics of Salakhani, local variety of Iraq and Zivzik (Punica granatum L.), local variety of Siirt, were compared. Salakhani variety, which is one of the well-known pomegranate cultivars in Halabja region, has been cultivated for centuries in this region, North of Iraq. Zivzik variety is considered to be one of the important local varieties in Siirt province in the South East of Turkey. Salakhani variety was collected from their natural area in Halabja and Zivzik variety was collected from Zivzik Village in Şirvan. This is the first study comparing both varieties in point of pomological and morphological features. Our study has shown that two varieties are similiar on account of some features on the other hand are also different with regard to some properties. In addition to that the study showed Salakhani has more bigger fruit size and with soft seed than Zivzik pomegranate; conversely, Zivzik cv. has also very juicy fruit and high quality of fruit juice compare with Salakhani. This study has shown the superior characteristics of these two varieties can be the subject of different breeding studies in developing new pomegranate varieties. © IJSM 2019.
Some Physical and Chemical Properties of Cold-Resistant Walnut Genotypes (Juglans Regia L.) From Van Lake Basin
(Centenary University, 2016) Başer, S.; Kazankaya, A.; Doğan, A.; Yaviç, A.; Çelik, F.
One of the most important climatic factors is spring late frost that adversely affects walnut growing. Particularly the green shoot heads damaged from cold weather, when the temperature decrease -2-3°C, after starting of walnut vegetation. Turkey’s walnut production and yield were dramatically decreased during the late spring frost in 2013. 83 genotypes were marked in Van Lake zone during 2013. The present study carried out during 2014-2015 and the late vegetates walnut populations were investigated. 25 genotypes were selected based on the seed weights of the walnuts. The seed weights were 11.46-16.25 g, the shell weights were 4.46-8.27 g, the inner ratios were 45.79-61.08 %, the protein ratios were 12.55-21.34 %, total oil ratios were 63.99-69.34 %, humidity ratios were 2.09-3.87% and the ash ratios were 1.33-2.50 %. Additionally, The macro and micro elemental analysis of the seeds were carried out and % 2.44 N, 297.5 mg P, 442.6 mg K, 331.9 mg Mg, 186.8 mg Ca, 169.1 mg S, 1.88 mg Na, 2.58 mg Fe, 2.86 mg Mn, 2.29 mg Zn ve 1.34 mg Cu values were observed. © 2016, Centenary University.
