Effects of Region and Age on Nut Quality of Major Chestnut Cultivars (Castanea spp.) cultivated in the Central Region of Korea

摘要

This study was conducted to investigate the effects of region and age on nut quality of major chestnut cultivars (Castanea spp.) cultivated in the central region of Korea to provide basic data for nut quality control and processing of postharvest. Inthe survey of by regions and ages, Buyeo and 'Hyogo57' showed the highest value by regions and cultivars, respectively. Also, there were statistically significant differences among regions and cultivars in the value of soluble solid content and kernel hardness. In the soluble solid content, Gongju showed the highest value among regions, and 'Tsukuba' among cultivars was the highest, 20.5%. Cheongyang showed the highest value of kernel hardness among regions, and 'Tanzawa' among cultivars showed the lowest value of kernel hardness, 8.75 kg/cm~2. In 'Tanzawa', 'Okkwang' and 'Tsukuba', soluble solid content and kernel hardness showed statistically significant differences according to age, but no correlation with age.
