摘　　要：以罗田板栗主栽品种中果早栗为试材,研究其不同采收期主要营养成分含量的变化。结果表明,随着板栗的成熟,其水分逐渐降低,而淀粉、蛋白质、可溶性糖、脂肪和维生素C都呈上升趋势,成熟Ⅰ期和成熟Ⅱ期的水分、可溶性糖、脂肪和维生素C含量差异不显著,淀粉和蛋白质含量差异显著;而未成熟中果早栗与成熟Ⅰ期和成熟Ⅱ期的中果早栗各营养成分均具有显著差异。充分成熟的板栗,果实代谢处于最低水平,具有较好的商业贮藏性能。为防止板栗充分成熟后栗苞开裂致使栗果落地造成损失,建议在成熟期Ⅰ时一次性打落进行采收。The main nutrient ingredients of three different maturity of chestnut 'Zhongguo zaoli' were analyzed.The results showed that when the chestnut was in its growing period,the moisture content decreased,and the content of starch,protein,soluble sugar,fat and vitamin C increased.There was no significant difference among the content of water,soluble sugar,fat and vitamin C in maturity Ⅰ and Ⅱ of Zhongguo zaoli while significant difference among the content of starch and protein in maturity Ⅰ and maturity Ⅱ of chestnut was observed.However,all the nutrient ingredients in maturity Ⅰ and Ⅱ of Zhongguo zaoli had significant difference.As a result,a better commodity and storing performance of chestnut was obtained in its maturity Ⅱ period,for it could accumulated more nutrients,and the metabolism was in the lowest level.The chestnut should be beating in maturity Ⅰ in order to prevent the lost from falling the maturated nut.
