Dynamics of zeatin riboside content in leaves and roots of two rice varieties at two developmental stages under the infestation stress by the brown planthopper, Nilaparvata lugens (Stl) (Homoptera: Delphacidae);

Results indicated that the concentration of zeatin and zeatin riboside(Z+ZR)both in roots and in leaves increased quickly in 0.
