Localization and changes in the activity of β-glucosidase were investigated in wheat caryopsis and glumes infected with Stagonospora nodorum as well as in lily ovaries and harvested tomato fruits both inoculated with Botrytis cinerea. It was established that the pathogen invasion caused splitting of wheat seed coat, xylem blocking in lily carpel and decay in tomato fruits. B. cinerea invasion evoked disorders of the embryogenesis accompanied by a decreased activity of β-glucosidase in all ovules. The activity of the enzyme was not changed considerably in wheat seeds as the infection occurred in the late embryonal stages and the embryonal processes were not affected. In the seeds of harvested tomatoes distant from the invaded area the enzyme activity was not changed as well.
