摘　　要：在黄瓜幼苗子叶期及第一真叶期用不同浓度的氯钾离子共体液进行诱导处理,测定黄瓜叶片中的酶活性。结果表明：诱导后各处理的SOD活性均显著高于对照,且呈先升高后降低的趋势,到诱导后10 d各处理达到最大值;POD活性也呈先升高后降低的趋势,诱导初期对照和各处理变化平缓,10 d后急剧升高,15 d达最大值,之后下降,且经诱导后各处理均高于对照;脲酶活性均高于对照,随着时间的推移呈先升高后降低的趋势,诱导后10 d达到峰值。在诱导物浓度为0.5%~1.5%的范围内,黄瓜叶片内各生理生化指标较对照差异最大。It was conducted that cucumber seedings were induced by copolymer of chlorine and potassium ions with different concentration at stage of cotyledon and the first true leaf the enzymatic activity of leaves were determinated.The results showed that the activity of SOD were higher than that of control,and the tendency that increased firstly,then decreased,they were at the peak base after induced 10 days.the tendency of POD activity increased firstly,then decreased too,control and treatmeats change slowly at the induced infancy,increased sharply after 10 days,they were at the peak base after induced 15 days,all treatmeats were higher than control obviously.the activity of urease increased instantly after induce,the activity of treatments and control were the largest after 10 days.when the concentration of copolymer of chlorine and potassium ions were 0.5% to 1.5%,the physiological and biochemical index of treatments changed obviously.
