Kernel sugar components of Turkish and foreign apricot (Prunus armeniaca l.) varieties

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 detected 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/100g sucrose, 1.50-2.52 g/100g maltose, 3.38-3.72 g/100g 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.
