| Die Intensivierung der Landwirtschaft hat zum Rückgang vieler Ackerwildpflanzen geführt. Der Ökologische Landbau bietet günstige Voraussetzungen für ihren Schutz. Wie entsprechende Populationen etabliert werden können, untersuchte ein Verbundprojekt der Bayerischen Landesanstalt für Landwirtschaft, der Technischen Universität München und der Universität Kassel. Die AG Freising untersuchte drei seltene winterannuelle Arten (Consolida regalis, Legousia speculumveneris, Lithospermum arvense) in mehrfaktoriellen Feldversuchen, in Praxisaus-saaten auf Bio-Betrieben sowie in Gewächshausexperimenten. Messgrößen waren Individuendichte, Samenproduktion und Bodensamenvorrat der Zielarten, zudem wurde der Ertrag der Feldfrüchte bestimmt. Frühe Herbstsaaten und... |

| Due to recent intensification of land use the arable flora is considered to belong to the most threatened groups of plants in Europe. Therefore, the objective of the project ‘re-introduction of rare arable plants on organic farms in Germany’ is to develop methods for a successful re-establishment of arable plants on fields with favourable management conditions. The present study describes the effects of different cover crops and crop rotations on the establishment of three endangered species (Consolida regalis, Legousia speculum-veneris, Lithospermum arvense) in a field experiment at Gräfelfing close to Munich. Results from the first 3 years indicate that successful establishment mainly depends on crop competition during the 1st year. As individual species... |

| Intensive land use has led to a drastic decline of arable weeds in Central Europe. The objective of the project “Restoration of local populations of rare and endangered arable field plants on organic farms in Germany” is to develop methods for a successful re-establishment of arable weeds on fields where absence of herbicides provides favourable development conditions. Two complementary approaches are tested by research teams at Freising and Witzenhausen. In Freising two exact trials were set up in order to find suitable crops and dates for the initial sowing of three rare and endangered species (Consolida regalis, Legousia speculum-veneris, Lithospermum arvense). The study area is located in the Munich Plain which is characterized by limestone gravel.... |
