BR与S_(3307)复合剂对黄瓜壮苗及内源激素含量的影响

Effect of BR and S_(3307) Mixture on Cucumber Sprout Growth and Endogenus Hormones Content

利用BR与S3307混合对津研四号黄瓜进行浸种处理,结果表明,BR与S3307只有在较低浓度下混合,才起到显著的壮秧效应。BR与S3307复合处理降低了茎的IAA、GA含量,提高了ZR含量;提高了根的IAA和ZR水平,降低了GA含量;提高叶片IAA、GA和ZR含量,降低ABA含量,从而起到降低茎长,促进根、叶生长的作用。

The mixture of BR and S3307 was firsdy used by soaking seeds of ＂Jin Yah IV＂ cucumber （Cucumis sativus L. ）. The result suggested that the mixture wouldn＇t have outstanding effect of making sprouts robust unless BR and S3307 were mixed on lower concentration. The mixture of BR and S3307 treatment decreased IAA,GA contents and increased ZR content in stem, raised IAA.ZR contents and dropped GA content in root, heigthened IAA.GA,ZR contents and lowered ABA content in leaf, thus made sprout height drop and the growth of root and leaf improve.
