黄花蒿化感物质对受体燕麦化感作用机理的初步研究

Effect of extraction of Artemisia annua on activity of some enzymes in Avena fata

测定了不同浓度的黄花蒿水提取物对燕麦植株体内几种酶活性（12-60 h）的影响.结果表明：黄花蒿水提取物可抑制燕麦体内多酚氧化酶（PPOD）、超氧化物歧化酶（SOD）、过氧化物酶（POD）、过氧化氢酶（CAT）等抗性酶的活性,提高苯丙氨酸解氨酶（PAL）的活性.

The effect of extraction with different concentration of Arternisia annua was studied on the activity of some enzymes in the receptor Arena fata from 12 h to 60 h of treatment. The result indicated that the extraction inhabited the activity of polyphenoloxidase （PPO）,hyperoxide mutase （SOD）, peroxidase （POD） and catalase （CAT）. However,the activity of PAL was increased.
