Abstract: Examine the progenitive power of Botrytis cinerea among three different virulence isolates which were cultured on Botrytis cinerea. The results showed that the progenitive power had significant differences: B.mucronatus>avirulent B.xylophilus>virulent B.xylophilus. All experienced nematode isolates could release superoxide anion (O·2). There was inverse-correlation between virulent level and O·2 content: progenitive power and their virulence level was not obvious; but the activity of O·2 in nematode was involved in their virulence level.
