| 摘 要： | ＤＰＣ系统化控改善了侧根组织中内源激素的水平，其中ＣＴＫｓ中的活性组分ｉＰ＋ｉＰＡ的含量水平提高，而ＤＨＺ＋ＤＨＺＲ和Ｚ＋ＺＲ的含量水平下降（苗期除外）；ＧＡｓ中ＧＡ３含量下降而ＧＡ４６月１７日前高于对照。ＩＡＡ含量在６月１７日前比对照高，ＡＢＡ则只在苗期（５月１８日）和实花期（６月３０日至７月８日）高于对照。ＩＡＡ／ＣＫｓ，ＩＡＡ／Ｚ＋ＺＲ和ＩＡＡ／ＡＢＡ在根系一生中较对照高。

| Abstract: | The content of plant hormone in root has been improved by DPC treatment.The content of iP iPA has been increased but DHZ DHZR and Z ZR have been decreased.The content of GA 3 was lower than control,but the GA 4 was higher than control before 06 17.The contert of IAA was higher than control before 06 17,but ABA was lower than control except 05 18 and 06 30-07 08.The ratios of IAA/CTKs,IAA/Z ZR and IAA/ABA are higher than control in root development period. |
