Abstract

Triticale is a frequently cultivated and used in feed rations because of high yields of kernels and straw. Furthermore triticale is cosidered in a culturelandscape program. The storage of triticale and storage conditions become more and more important. In our study Triticale was remoistered to a watercontent of 14, 16, 18, und 19% as well, inoculated withP verrucosum and stored for 28 weeks from november till july in a research granary (tower silo). This experiment should simulate the storage situation in farmscale from cold wintermonths to warm spring times. Every four weeks CO2 was measured, and samples for moisture, OTA- and CT-analysis were taken. At week 20 and a MC of 19 % 22 μg OTA/kg triticale were found. The maximum of OTA-production in this humidity stage was at week 28 with 635 μg/kg. Also at a MC of 18 % OTA could be found with levels near to the detection limit. In contrast to former investigations with oatsP verrucosum produced in triticale no citrinin even when the OTA concentrations were higher than in our investigations.
