Abstract:
Using v ertical g el elect rophoresis, we s tudied the correlation between peroxidase isoenzymeand soybean rust of dif ferent s everit y and different distance apart f rom diseas e spot’ scenter and dif ferent time af ter inoculation in resis tant and susceptible varieties. The resultsshowed that there was one or tw o more isoenzyme pat tern bands in diff erent inf ection s everit y( from Ⅰ to Ⅲ grade) than CK t reatment ( Uninoculated, 0 g rade) . Peroxidase activi ty f romhigh t o low was Ⅱ grade> Ⅰ g rade Ⅲ g rade> 0 grade. The closer dist ance apart f rom diseasespo t’ s center and the period aft er inoculation in resis tant and susceptible varieties themore s tronger activit y and the more enzyme pat tern bands. Comparing resis tant and susceptiblev arieti es at the same time af ter inocula tion, the resis tant one had 1 to 4 more enzyme pattern bands and s t ronger enzyme activit y than sus ceptible one. Besides there was clos e correlationbetween RF value ( 0. 78 to 0. 85) and development of soybean rus t.
