摘　　要：在黄瓜幼苗子叶期及第一真叶期用浓度为0．2％，0．5％，1．0％，1．5％，2．0％的氯钾离子共体液进行诱导处理，结果表明：诱导后可溶性糖含量均显著高于对照，且呈先升高后降低的趋势，15d后各处理达到最大值；叶绿素含量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，10d后急剧升高，15d达到最大值，各处理均高于对照；单宁含量诱导后即开始升高，15d达到峰值，阿魏酸含量前期变化平缓，15d后急剧升高，20d后达到峰值，绿原酸含量诱导后急剧升高，5d后即达到最大值；木质素的含量各处理均高于对照。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 seedlings were induced by copolymer of chlorine and potassium ions with 0.2 %, 0.5 %, 1.0 %, 1.5 % and 2.0 % concentration at stage of cotyledon and the first leaf, The results showed that Soluble suger content were higher than that of control, and the tendency that increased firstly, then decreased, they were maximum after induced 15 days. Chlorophyll content present the tendency as that of soluble suger content, control and treatments change slowly at the initial stage of induced, increased sharply after 10 days, they reached the peak base after induced 15 days, all treatmeats were higher than control obviously, the content of tannin increased instantly after induce, the content of treatments and control were the largest after 15 days. ferulic acid content change slowly at the prophase, rised sharply after 15 days, which reached the peak base after 20 days. Chlorogenic acid content rised shaply after induced, which were maximum after induced 5 days. Lignose content of treatments were higher than that of control, 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.
