垫江白柚贮藏生理及防止粒化方法研究

 研究了冷激处理、药剂处理对垫江白柚果实生理代谢及相关酶活性的影响。结果显示：冷激可显著抑制柚果的呼吸强度，冷激和药剂处理均可有效降低无氧呼吸产物乙醇，膜脂过氧化产物丙二醛(MDA)的累积速率，另外可增加果皮POD酶活性，改变其酶活性变化趋势，使纤维素酶在贮藏中前期维持较低的水平，推迟粒化出现的时间，减轻发生的程度。

Pummelo Fruit Physiology and Granulation Control During Storage

The physiology and relative enzymes of “Dianjiang” Pummelo fruit, treated with cold shock and chemicals, were tested during the storage. The experiments showed that the cold shock inhibited its respiration rate. Both the cold shock and chemicals gave rise to the fruit to produce less ethanol while respiring anaerobicly and to accumulate less MDA membrane lipid peroxidation products. In addition, they increased peroxidase (POD) activity in the fruit peel and changed its variation tendency, maintained lower cellulase activity activity during early and middle storage time.They also made the fruit granulate late and reduce granulation incidence.
