| 摘 要： | 以甜椒为试材,用不同外源激素进行浸种和幼苗叶片喷洒,测定其长势和生理指标.结果表明:S3307和IBA NAA浸种处理、6-BA和GA3叶面喷洒处理叶片数和叶面积不断增大.S3307、GA3和6-BA处理的单株产量显著增加,以S3307、GA3增产效果最好.S3307处理的全株干物质重最高,较对照增加了33.97%,其次为GA3、6-BA和IBA NAA处理.S3307、6-BA和IBA NAA处理也可减缓甜椒生长后期叶片叶绿素和可溶性蛋白含量的下降,以S3307处理效果最明显.同时4种处理均可提高SOD、POD活性,降低MDA含量,并延缓SOD、POD活性下降和MDA含量的增加,延缓效果为S3307＞6-BA＞IBA NAA＞GA3.

| Abstract: | The experiment was conducted with seeds and seedlings of sweet pepper,treated by different exogenous hormones,to probe into effection to growth and senescence in sweet pepper.The results showed,treated by S3307,IBA NAA,6-BA and GA3,they significantly increased leaves number and leaf area Index.Meaniwhile,they increased plantlet yield and staved drop speed of chlorophyll and soluble protein content except GA3.In addtion,they also increased dry matter weight and MDA content and improved activity of SOD and POD treated by 4 exogenous hormones. |
