摘要
在大田条件下,以垦农4号为试验材料,研究了不同植物生长调节剂对大豆生育后期根系内同化物及内源激素的变化情况。结果表明:SODM调节剂明显提高了大豆根系中的可溶性蛋白含量,增加了根系内游离氨基酸的输出量,氯化胆碱和DTA-6调节剂表现不明显。喷药后5~30 d,氯化胆碱有效地降低了根系中ABA含量,SODM和DTA-6调节剂有效地提高了大豆根系内CTK和GA含量,而对IAA含量的促进并不明显。至喷药后20~30 d,SODM和DTA-6调节剂处理的根系ABA含量才有所降低。
Field experiments researched the effects of different plant growth regulators (PGRs)on the change of assimilation and hormone in bleeding sap of soybean (Kennong 4)roots. The results showed that:SOD simulation material ( SODM ) significantly increased on content of the soluble protein in soybean. On the other hand, SODM application also increased the content of the free amino acid output in soybean roots, Choline chloride( Cc)and diethyl aminoethyl hexanoate (DTA-6)treatments were not significant; After spraying 5 - 30 d, Cc effectively reduced the content of ABA in soybean roots, SODM and DTA-6 regulators were effective to improve the content of GA and CTK in soybean roots, and the content of IAA was not. Days after spraying 20 - 30 d, SODM and DTA-6 had been reduced on content of ABA.
