Název v původním jazyce

Common sunflower (Helianthus annuus var. anuus) ? potential threat to coexistence of sunflower crops in Central Europe

Popis výsledku v původním jazyce

Common sunflower (Helianthus annuus var. annuus) has been found in the Czech Republic since the 1960?s. This species exists as a ruderal on railways and at river ports. It has been reported twice on arable land but its presence was only temporary. In 2004, we have found a dense population of sunflower on arable land. The infested crop was sunflower with common sunflower plants dispersed mainly in the field margins, however some plants were in the mainpart of the field. Common sunflower was also growingin ruderal habitats near the field. We predict the following consequences of common sunflower spread through the country: it could become a problem weed in sunflower crops due to the non-availability of a selective herbicide; as a weed, this species could infest other crops, which currently suffer from volunteer sunflower occurrence, such as maize, beet or soybeans. Gene flow can occur between this weedy form and the crop, and this must be considered during the risk assessment of transge
