研究了竹笋在 ５℃ 和 １０℃下，木质素含量、Ｈ２Ｏ２含量、超氧化物歧化酶（ＳＯＤ）活性、过氧化氢酶（ＣＡＴ）活性和过氧化物酶（ＰＯＤ）活性的相互关系和变化规律。结果表明，ＳＯＤ、ＣＡＴ和 ＰＯＤ ３种酶活性虽均呈先上升后下降趋势，但 Ｈ２Ｏ２呈持续上升趋势，由于 Ｈ２Ｏ２的积累，致使木质素含量不断增加。５℃的 ＳＯＤ、ＰＯＤ活性和 Ｈ２Ｏ２含量均显著低于 １０℃下的数值，５ ℃下木质素含量极显著低于 １０℃下的数值。
The correlation and change of lignin content, H2O2 content, superoxide dismutase (SOD) activity, catalase (CAT) activity and peroxidase (POD) activity of bamboo shoots were studied at 5 ℃ and 10 ℃ law. The results showed that the activities of SOD, CAT and POD increased firstly and then decreased, but the H2O2 showed a continuous upward trend. Due to the accumulation of H2O2, the content of lignin increased continuously. The activities of SOD, POD and H2O2 at 5 ℃ were significantly lower than those at 10 ℃. The content of lignin at 5 ℃ was significantly lower than that at 10 ℃.
