摘要: 【目的】 研究采收成熟度对核桃青皮褐变及其相关代谢酶的影响,分析核桃青皮褐变发生机制,为生产中核桃适宜采收期的确定及其褐变定向调控提供理论依据。【方法】 以温185青皮核桃为试材,分别于8月22号(成熟度Ⅰ,花后125 d)、8月27号(成熟度Ⅱ,花后130 d)、9月1号(成熟度Ⅲ,花后135 d)采收,置于(-1±1)℃,相对湿度为75%~85%条件下贮藏,定期测定不同采收成熟度核桃青皮褐变指数、总酚含量及褐变代谢相关酶。【结果】 青皮成熟度不同,褐变指数不同,成熟度Ⅱ(8月27日)采收的核桃青皮贮期褐变指数显著低于其它2个成熟度,总酚及PPO、POD、PAL、SOD、CAT及APX活性显著高于其它两个成熟度,温185核桃青皮褐变与总酚及PPO、POD、PAL、SOD、CAT及APX活性存在极显著负相关关系。【结论】 成熟度Ⅱ(8月27日)是温185青皮核桃适宜采收期,其贮期青皮褐变与总酚含量及PPO、POD、PAL、SOD、CAT及APX活性密切相关。
