Abstract:
The influence of IBA，ABT1 and Agrobacterium rhizogenes on the softwood cutting of Tilia platyphyllos Aurea was studied during rooting while the mechanism of their effects on the rooting was discussed.The results showed that the rooting rate，average root number，root length were significantly increased(P<0.01) and the rooting time decreased after treatment with IBA，ABT1 and Agrobacterium rhizogenes. IBA,ABT1 and Agrobacterium rhizogenes also increased significantly the contents of GA3，IAA and the ration of IAA/ABA(P<0.01)，the variation of soluble sugars and total N contents were the same，the contents of soluble sugars and total N rised firstly and fell lastly，no significant difference.The contents of ABA and hydroxybenzene reduced during the rooting period,and promoted remarkably rooting of softwood cutting.It showed that the treatment with 500 mg?kg-1ABT1 and Agrobacterium rhizogenes was the best. The rooting percentage,quantity of root and root length of the cutting after treatment with ABT1+Agrobacterium rhizogenes increased by 112.36%,112.61% and 64.95%,while the rooting period was shortened by eight days compared with control.
