Fruit Characteristics of Selected Chestnut (Castanea Sativa Mill.) in Inebolu (kastamonu/Turkey) District
(International Society for Horticultural Science, 2009) Yarilgaç, T.; Çolak, F.; Balta, M.F.
In the Inebolu (Kastamonu) district of the West Black Sea Region, there are many chestnuts (Castanea sativa Mill.) trees. This study was carried out to determine promising chestnut genotypes and fruit samples from 62 trees representing the population that was investigated. The selected superior chestnuts had a nut weight between 5.68±0.35 g and 11.94±0.33 g, a kernel weight between 4.97 g and 9.79 g, a kernel ratio between 77.33% and 86.25%, shell thickness between 0.25 mm and 0.44 mm, fruit width between 16.11±0.47 and 20.48±0.87 mm, fruit length between 25.91±0.53 mm and 34.93±0.47 mm and fruit height between 23.87±0.45 mm and 34.89±0.28 mm and number of nuts/kg between 83 and 169. In addition, Chestnuts were determined as fruit characteristics brightness and harshness of shell, color of shell, color of kernel, peeling of testa, number of nut/kg. The data were evaluated by the weighted-rankit method. Relative scores of the chestnuts for general quality, nut size and suitability to chestnut paste were examined.
Hplc Determination of Sugar Contents Based on Harvest Season in Almonds
(Chemical Publishing Co., 2007) Balta, M.F.; Yörük, I.H.; Dogan, A.; Erez, M.E.; Battal, P.
This study presents in comparison with harvest seasons sugar contents in 18 promising almond selections [Prunus dulcis (Mill.) D.A. Webb.] from Balikesir (western Anatolia, Turkey). Their majority had kernel weight over one gram since large kernel is a desired fruit characteristics for almond breeding efforts. Nuts of almond genotypes were collected at two seasons based on their harvest times. The harvest seasons were late August for 8 promising genotypes and early September for other 8 genotypes. Sugar contents were detected by HPLC Selections harvested in late August and early September averagely contained 2.19-2.31 g/100 g sucrose, 0.68-0.92 g/100 g maltose, 2.09-1.82 g/100 g glucose and 4.08-3.41 g/100 g fructose. Sugar contents of selections did not differ by harvest season statistically. Whereas, significant differences were found among selections for each harvest season. In addition, the mean sugar was fructose in 12 genotypes, sucrose in 4 genotypes and glucose in one genotype.
Kernel Sugar Components of Turkish and Foreign Apricot (Prunus Armeniaca L.) Varieties
(Chemical Publishing Co., 2008) Yarilgaç, T.; Bostan, S.Z.; Karadeniz, T.; Balta, M.F.
This study involves in determining kernel sugar contents of Turkish apricot varieties (Kabaasi, Sakit, Alyanak, Tokaloglu, Salak, Hasanbey, Hacihaliloglu and Sekerpare) and foreign apricot varieties (Paviot, Colomer and Thyrinte) grown in Van (eastern Anatolia, Turkey). The sugar contents of kernels were detepted by HPLC. The main sugar was sucrose in the majority of apricot varieties. Kernels of Turkish varieties contained 2.20-5.30 g/100 g sucrose, 0.40-3.40 g/100 g maltose, 0.90-3.64 g/100g glucose and 0.57-5.58 g/100 g fructose. Sugar contents of seeds belonging to foreign varieties were 3.30-4.67 g/100 g sucrose, 1.50-2.52 g/100 g maltose, 3.38-3.72 g/100 g glucose and 1.86-2.93 g/100 g fructose. Sugar contents significantly, differed by varieties. In addition, positive correlation coefficients were computed among kernel sugars.
