| 摘 要： | 将山楂种子层积处理一个冬季,测定层积前后酚代谢酶活性的变化。结果表明,山楂种子层积后,PPO和POD活性升高,PAL活性降低,促进酚类物质的氧化分解,不利于酚类物质的合成,从而降低酚类物质含量,促进种子萌发。

| Abstract: | The seeds of Crataegus pinnatifida Bag were stratified for a winter,after which the changes of some phenol metabolism enzymes were studied.The result showed that after being stratified for a winter,the activity of phenol synthetase PAL increased and the activities of the lyases PPO and POD decreased,which was good to the phenols decomposition,but not good to their synthesis.This was the reason why phenols content decreased,and seeds germination was improved. |
