INFLUENCE OF MECHANICAL WOUNDING OF HIPPEASTRUM X HYBR. HORT. BULBS ON INFECTION BY STAGONOSPORA CURTISII (BERK.) SACC.

A. Saniewska
It was found that Stagonospora curtisii easily infected mechanically-injured basal plate and scales of Hippeastrum inoculated directly after cutting. The ability of the fungus to infect mechanically injured basal plates and scales decreased; however, with prolongation of time the reddish coloration increased at the same time. Finally, inoculation by S. curtisii of tissues 5 days after cutting when intensive reddish coloration developed on surface of these organs, resulted in lack of infection.

The powdered reddish colored tissue of scales or the red compound extracted with acetone from bulb scales significantly inhibited mycelium growth of Stagonospora curtisil on PDA and LBA media.
