Abstract
The infection of Sphaerotheca fuliginea resulted in an increase in activities of phenylalanine ammonialyase,peroxidase and polyphenol oxidase in squash leaves.Activities of the three enzymes showed two peaks in the two tested squash cultivars.The increase of the enzyme levels in Cucurbita muschata leaves(resistant cultivar) was greater than that in C.maxima(susceptible cultivar).These results suggested that the early rapid increase of polyphenol oxidase may serve as one of the physiological indices for the selection of C.muschata.
