Dynamics of above-ground and below-ground biomass of Rumex crispus, Rumex obtusifolius and the new weedy species Rumex hybrid cv. OK-2 (R. patientia x R. tianschanicus) in the seeding year

Popis výsledku v původním jazyce

Docks can be serious weeds of arable land and permanent grasslands where they can persist through well-established root systems. A Rumex hybrid (R. patientia x R. tianschanicus, cv. OK-2, Uteusha) has been planted as a forage and energy crop since 2001 in Czechia and has now become a new weed species. As its ecological characteristics are unknown, there is a need for improved knowledge for developing control measures and strategies. In 2010 and 2011, we performed a tube pot experiment to investigate above-ground and below-ground biomass growth dynamics and below-ground biomass allocation of Rumex OK-2. We compared the hybrid with Rumex crispus and Rumex obtusifolius during the vegetation season in the seeding year. Above-ground and below-ground biomass of Rumex species tended to increase from July to September. In the seeding year, flowering was recorded only for one plant of Rumex OK-2 and 27,5% of R. obtusifolius plants, whereas R. crispus did not flower. The proportion of below-ground biomass of R
