研究了广东省主栽石硖龙眼（ＤｉｍｏｃａｒｐｕｓｌｏｎｇａｎａＬｏｕｒ．ｃｖ．Ｓｈｉｘｉａ）品种的低温贮藏、冷害及其生理生化反应，结果表明：０℃下贮藏１４天果实开始表现冷害，２１～２８天发生不可逆冷害，果实受冷害后果皮细胞膜透性增大，呼吸作用异常升高，过氧化氢酶（ＣＡＴ）与超氧化物歧化酶（ＳＯＤ）活性明显降低，好果率显著下降，贮藏期缩短。在８℃下贮藏２１天表现褐变与腐烂。在４℃下贮藏既不表现冷害，褐变也只在贮藏３０天以后才开始表现。贮藏中乙烯释放量一直保持低水平，未出现高峰
The effects of cold storage, chilling injury and physiological and biochemical reactions on Dimocarpus longana Lour.cv.Shixia cultivars in Guangdong Province were studied. The results showed that cold storage was observed in fruits stored at 0 ℃ for 14 days, irreversible chilling injury occurred in 21-28 days, The pericarp membrane permeability increased and the respiration rate increased abnormally after chilling injury. The activities of CAT and SOD decreased significantly, the good fruit rate decreased significantly and the storage period shortened. Storage at 8 ℃ for 21 days showed browning and decay. Stored at 4 ℃ neither show chilling injury, browning only after 30 days of storage began to show. Ethylene emissions during storage have remained low, there is no peak
