Abstract

Concentrations of fungal metabolites were measured in 32 wheat grain samples from north-eastern Poland in 2003. The samples originated from fields cultivated conventionally (but varying in chemical protection level) or cultivated organically. Concentrations of Fusarium toxins (HT-2, DON, 3-AcDON, NIV), trichodiene, microbial biomass indicators (fungal ergosterol and general adenosine 5'-triphosphate (ATP)) and seed vigour were assessed. A large variation between samples was observed, depending on their origin. Seed from organic farms contained similar amounts of Fusarium toxins but more ergosterol and ATP than conventionally grown and chemically protected seed. The highest levels of toxins and ergosterol were detected in samples from conventional cultivation lacking chemical protection. Intensive agronomic practices (including complete chemical protection) significantly lowered the levels of ergosterol, ATP and trichodiene, as compared with other cultivation systems.

2003年波兰东北部天然污染小麦样品中镰刀菌毒素和真菌总生物量指标。

2003年，在波兰东北部的32个小麦样品中测定了真菌代谢物的浓度。样品来自常规耕作(但化学防护水平不同)或有机耕作的田地。测定镰刀菌毒素(HT-2、DON、3-AcDON、NIV)、trichodiene、微生物生物量指标(真菌麦角甾醇和5′-三磷酸腺苷(ATP))和种子活力的浓度。根据样品的来源不同，观察到样品之间存在很大差异。来自有机农场的种子含有类似数量的镰刀菌毒素，但比常规种植和化学保护的种子含有更多的麦角甾醇和ATP。在缺乏化学保护的常规栽培样品中检测到的毒素和麦角甾醇含量最高。与其他栽培系统相比，集约化农艺实践(包括全面的化学保护)显著降低了麦角甾醇、三磷酸腺苷和trichodiene的水平。
