This method is more advantageous than the classical one of ion leakage measurement.展开更多

Inducer inoculum with virus, bacteria, fungus and the metabolites of pathogen or non-pathogen can systemically protect host plants from disease caused by certain pathogen. Abroad, many successful cases of induced resistance are documented in Refs. [1-5] such as tobacco, pear, apple, kidney bean, cucumber, potato, and much work on tobacco. The disease caused by Phytophthora melonis is one of the展开更多

INTRODUCTIONCooking was the first who succeeded in getting a large number of protoplasts by using the enzymatic method in the 1960s. Now protoplasts have become an important tool in the research of plant physiology, plant genetics, phytopathology and membrane physiology.
