title: [The relationship between activities of chitinase and beta-1,3-glucanase and resistance to rhizomania in sugar beet].
abstract: The relationship between activities of chitinase and beta-1,3-glucanase and resistance to rhizomania of sugar beet were studied in diseased soil and disease-free soil by using a method of comparative physiology. Two resistant varieties and two susceptible ones of sugar beet were used in this experiment. Chitinase and beta-1,3-glucanase activities of the resistant varieties were higher than the susceptible ones in either diseased soil or disease-free soil. There is a positive correlation between chitinase, beta-1,3-glucanase activity and yield of beet in diseased soil, suggesting that pathogen infection can induce resistance to rhizomania through activating chitinase and beta-1,3-glucanase.
