Effects of 5-Aza and Other Extraneous Substances on the Changes of Morphology and Protein of Paulownia Seedlings with witche’s Broom

The paper take the seedlings of p.tomentosa×p.fortunei paulownia infected witche’s broom as the experiment material.Reaserch on the effect on the morphological and the preotin change that treated by different concentration of 5-Aza and rifampin.The main results are as following: Appropriate concentration of 5-Aza and rifampin can restrain paulownia witche’s broom.Treament of 150 μmol·L-15-Aza+80 mg·L-1 rifampin can restrain paulownia witche’s broom.The protein(pI 6.8、m24ku) exist in the healthy seedlings can not be observed in the seedlings of witche’s broom.This indicate that the protein possibly has some realationship with paulownia witche’s broom.
