Abstract

Abstract: Endophytic bacteria A-10' have remarkable preventive function to Potato bacteria ring rot． The paper studies the changes of the chlorophyll contents and the activity of several enzymes inside the plants of potato． After they have been treated with bacterial suspension of A-10'． The experiment result shows that，c ompared with the control， the activity of CAT，PAL and the content of chlorophyll in leaves of potato increased obviously and the content of solube protein reduced． The paper concluded that as the activity of the enzymes mentioned above and the chlorophyll contents are in positive relation to the disease resistance of plants． And the content of solube protein reduced showed that the germ reduce the damaging effects of bacteria on the organization．

Key words: B． stearothermophilus, Physiological and biochemical, Induced resistance, Potato
