| 摘 要： | 研究了IBA和发根农杆菌处理对糠椴嫩枝扦插生根的影响, 并对其影响生根的机理进行了初步探讨。结果表明: IBA和发根农杆菌处理显著( P < 0.01) 提高了插条生根率, 增加了成活苗的生根数和根长, 明显缩短了生根时间。IBA和发根农杆菌处理还显著( P < 0.01) 提高了插条生根期内源GA3和IAA、可溶性总糖和全氮的含量及IAA /ABA比值, 降低了ABA含量, 对糠椴嫩枝扦插生根有明显的促进作用, 其中以500 mg·kg-1 IBA +发根农杆菌处理的生根效果最好, 插条的生根率、成活苗的生根数、成活苗的根长分别比对照增加了122.08%、65.75%和23.63% , 生根时间比对照缩短了14 d。

| Abstract: | The influence of IBA and Agrobacterium rhizogenes on the softwood cutting of Tilia mandshurica was studied during rooting,while the mechanism of their effects on the rooting was discussed.The results showed that the rooting percentage and number of roots significantly increased(P<0.01)and the rooting time decreased after treatment with IBA and Agrobacterium rhizogenes.IBA and Agrobacterium rhizogenes also increased the IAA/ABA ratio and contents of IAA,GA3,soluble sugars,reduced ABA contents of cuttings during the rooting period,and promoted remarkably rooting of softwood cutting.It was showed that the treatment with IBA Agrobacterium rhizogenes was the best.The rooting percentage,quantity of root and root length of the cutting after treatment with IBA Agrobacterium rhizogenes increased by 122.08%,65.75% and 23.63%,respectively,while the rooting period shortened by 14 days compared with control. |
