A study of biological characteristics of both field and laboratory isolates revealed that
highly resistant isolates were morphologically different from their original wild types. The
majority of them were less pathogenic and produced less sclerotia than the original ones.
Significant negative correlation between osmotic sensitivity and the degree of resistance
was recorded. The correlation between micelium growth rate and resistance to dicarboximides
was also significant and negative. Growth medium, acidity and growth temperature
had less effect on the micelium growth rate of the highly resistant isolates than on the
sensitive ones. U radu su proučavane biološke karakteristike izolata B. cinerea različite osetljivosti na dikarboksimide. Utvrđeno je da se visokorezistentni izolati morfološki razlikuju od izolata normalne osetljivosti. Oni su uglavnom slabije patogeni i formiraju manji broj sklerocija od izolata normalne osetljivosti. Zabeležena je visoka negativna korelacija između osetljivosti na povećan osmotski pritisak i rezistentnosti na dikarboksimide, kao i brzine rasta izolata i rezistentnosti
na dikarboksimide. Uticaj temperature, vrste i kiselosti hranljive podloge na porast
micelije visoko rezistentnih izolata B. cinerea slabije je izražen u odnosu na porast osetljivih
izolata.
