Production, or not, of sclerotia by Aspergillus niger strain IBT 29019, IBT 24631, and IBT 24634, and production of apolar indoloterpenes on Czapek yeast autolysate agar with or without added plant parts.

*-: no sclerotia produced, +: few scattered sclerotia, ++: many sclerotia (>10) surrounding each piece of fruit, or directly on the rice or corn.**More indoloterpenes were detected using mass spectrometric detection than diode array detection in this case where both methods were compared. In IBT 29019 on CYAR, 4 recognizable indoloterpenes were detected using LC-mass spectrometric detection (in bold), but only two according to DAD.***−/+: sclerotia not produced in one experiment, but produced in the otherThe conidia were frozen at −18°C for three weeks before inoculation.
