Abstract

Abstract:

In order to study the expression of multiple rol genes,height-growth,rate of rooting,endogenous hormone (IAA,ABA) and other parameters of the triploid Populus tomentosa were measured. The results indicated that growth of some transgenic plants was inhibited while the rooting rates of all the transgenic plants were increased to various degrees. Compared with the transgenic plants with rolC gene,the plants transferred with rolB gene were higher in both the IAA content and the rates of IAA/ABA on average. The results showed that the plants with multiple copies of rol gene were able to generate a large number of hairy roots quickly.

Key words: rolgene, triploid Populus tomentosa, growth, endogenous hormone
