摘　　要：The activity of polygalacturonase inhibiting protein (PGIP)was assayed in four kind of cultures induced endo-polygalacturonase (endo-PG). It was discovered that endo-PG stimulated obviously the accumulation of PGIP. The PGIP contents of SuMai No. 3 and SA-Ⅱ cells,which are fungal disease-resistant,are higher than the contents of Mian Yang No. 11 and JingHua No.1. It is indicated in cell level that PGIP has relation to resistance of plant.The activity of polygalacturonase inhibiting protein (PGIP)was assayed in four kind of cultures induced endo-polygalacturonase (endo-PG).
