摘 要：
用蒸馏水、乙醇、丙酮作为浸提剂,通过浸提法获得西芹种子的浸提液,在黄瓜第1真叶横宽5cm时进行2次灌根处理,然后于不同时期对其叶片内超氧阴离子、过氧化氢含量进行测定。结果表明:西芹种子浸提液处理后的黄瓜叶片内超氧阴离子、过氧化氢含量在取样前期高于对照,后期低于对照。超氧阴离子含量较对照升高的幅度范围为蒸馏水-12.05%～38.52%、乙醇-24.41%～109.46%、丙酮-11.04%～166.10%;过氧化氢含量较对照升高的幅度范围为蒸馏水-36.38%～16.26%、乙醇-35.58%～14.52%、丙酮-34.27%～41.36%。

摘 要：
Distilled water,ethanol and acetone were used as impregmengt to obtain extract from the parsley seed.The extract was applied to the root of cucumber twice when first euphylla reached 5 cm wide and then the leaves were tested for content of superoxide anion and peroxide at different growing stages.The results showed that the content of superoxide anion and peroxide were higher than that of the control at early days and lower at later stage after treatment with extracts.The content of(O ·2) was higher than that of the control from-12.50% to 38.52% with distilled water extracts,-24.41% to 109.46% with ethanol extracts;-11.04% to 166.10% with acetone extracts.The content of H2O2 were higher than the control from-36.38% to 16.26% with distilled water extracts;-35.58% to 14.52% with ethanol extracts;-34.27% to 41.36% with acetone extracts.
