Investigation on Nut Development in Hazelnuts and Determination of Nut Characteristics and Variation Within Cultivars in Some Hazelnut Cultivars
(International Society for Horticultural Science, 1997) Bostan, S.Z.; Islam, A.; Şen, S.M.
This research was carried out onTombul, Kalmkara and Sivri hazelnut cultivars grown in Ordu and this study was consisted of 2 chapter. First chapter, nut length and width development of these cultivars were investigated in a hazelnut plantation involving these varieties. In the result, the width development was determined as 1, 921 cm, 1, 760 cm and 1, 621 cm, respectively; the length development was determined as 1, 930 cm, 1, 949 cm and 1, 835 cm respectively. Between plants and weeks were determined significant differences. In the second chapter, nuts were picked from average 35 hazelnut plantations in center and village. In these cultivars, nut weight, shell thickness, kernel weight and kernel ratio were determined as 1.552-2.662 g, 0.71-1.0 mm, 0.972-1.410 g, 50.51-65.06 %; 1.750-3.174 g, 0.66-1.09 mm, 0.184-1.709 g, 46 51-60.74 % and 1.669-2.605 g, 0.65-1.04 mm, 0.851-1.400 g, 48.53-56.34 %, respectively. In addition, coefficients of variation for nut weight, kernel weight and kernel ratio in cultivars were 10.05, 8.10, 5.73 %; 13.52, 14.17, 5.50 % and 10.24, 10.11, 3.86 %, respectively.
Studies on Selection of Apricots With Good Fruit Quality and Resistance To Late Spring Frosts in Gevaş Plain
(International Society for Horticultural Science, 1999) Akça, Y.; Şen, S.M.
Turkey exports more than 44.000 tons of dried apricot. For many years the apricot production of Turkey has been unregulated because of late spring frost. Resistance to late frosts, growth vigor, productivity, pomological and phenological characteristics were examined in native apricot at Gevaş in 1995 - 1996. Apricot trees with resistance to late spring frost were selected at 1730 m. The lowest temperature at full blooming time was - 1.2°C in 1995. The whole trees were damaged in flowering time, except 45 types that flowered 10-15 days later than Hasanbey and others trees. At the end of the study 28 types with high yield and resistant to late spring frost were selected. In these types, average fruit weight varied between 12.70±1.42 to 30.19 ±5.1 g. Seed weight varied from 0.88±0.1 and 2.07±0.2 g. Soluble solid content varied between 13.57±1.2 - 28.63±12.54.%.
