Abstract
The objective was to test the response of summer crops (Zea mays and Glycine max) and indicator plants to exposure to extracts of winter cover crops (Avena sativa, Lolium multiflorum and Triticum aestivum) regarding on seed germination. Bioassays were carried out to test six shoot extract concentrations, by using germitest paper maintained in controlled conditions. Zea mays, Glycine max, Lactuca sativa and Phalaris canariensis showed differential response to exposure to shoot extracts of Avena sativa, Lolium multiflorum and Triticum aestivum regarding on seed germination. Shoot extracts of Avena sativa and Lolium multiflorum increased seed germination while shoot extract of Triticum aestivum reduced seed germination of Zea mays. Shoot extracts of Avena sativa, Lolium multiflorum and Triticum aestivum reduced seed germination of Glycine max, Lactuca sativa and Phalaris canariensis.
