摘要: 对三种不同成熟度的板栗进行生理生化测定研究,结果表明:随着板栗成熟度的增大,其呼吸强度和水分含量渐渐降低,在保鲜贮藏过程中的失水率和霉变率也相应较低,充分成熟的板栗呼吸强度和含水量为3.41mgCO2/100g•h和48.95%,分别比成熟前10d采收的板栗低3.76%和10.01%;充分成熟的板栗,果实体内各种营养物质得到充分积累,具有较好的品质和抵抗外界不良环境的能力,也具有较好的耐贮性能。

Abstract: In this paper, the physiological and biochemistry assays of the chestnut harvested in different time were carried out.The results showed that the respiration rate and water content of chestnut gradually decreased with increase of ripeness degree.The proportion of dehydration and mildew was low during storage. The respiration rate and water content of ripe chestnut were3.41mg CO2/100g•h and 48.95% respectively and 3.76% and 10.01% respectively lower than the chestnut harvested ten daysearlier before ripeness. The nutrients of ripe chestnut were fully accumulated, so they had better storage trait.

Key words: chestnut, ripe degree, quality, storage trait
