摘要/Abstract

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 m andshuri
ca 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 p romoted remarkably rooting of softwood cutting. It was showed that the treat
mentwith IBA + Agrobacterium rhizogenes was the best. The rooting percentage, quantity of root and root
length of the cutting after treatmentwith IBA +Agrobacterium rhizogenes increased by 122.08%, 65.75% and
23.63% , respectively, while the rooting period shortened by 14 days compared with control.
