Abstract

Abstract:

The biochemical changes of suspension cell of the susceptible poplar and the resistant one through the interaction between suspension cell of poplar and the crude elicitor of Marssonina brunnea were determined. The results are as below: the production of active oxygen and the ΔpH of suspension cell of I-72 poplar were higher than Populus canadensis in whole process. There was no distinct difference on the quantity in the membrane lipid peroxidation (MDA) of suspension cell of P. canadensis and I-72, but the MDA rush hour in I-72 appeared one hour earlier than in the P. canadensis poplar. These could provide a foundation to understanding the resistant mechanism and the resistant gene of poplar.
