| 摘 要： | 本实验以3个熟性不同的莲藕品种为材料,研究了莲藕膨大过程中褐变酶活性的变化。实验表明:随着膨大节数的增加,过氧化物酶(POD)、多酚氧化酶(PPO)的活性增加;第4节藕体随着采收时间的推迟,褐变酶活性增加,且熟性不同品种之间有明显差异。并探讨了品种熟性、藕体大小和环境条件对莲藕褐变酶的影响。

| Abstract: | Three lotus (Nelumbo nucifera Gaertn) cultivars with different maturity were used to study the activities of browning enzymes, peroxidase(POD) and polyphenoloxidase(PPO) in rhizome tissues during rhizome swelling. Results showed that activities of POD and PPO increased with swelling of rhizome and delaying in harvesting date.The activities of browning enzymes in different cultivars were significant. The influences of maturity, rhizome size and environmental conditions on browning enzymes were also discussed. |
