Abstract
Response of the invasive species Heracleum mantegazzianum to experimental removal of tissues was studied in the Czech Republic The study aimed at determining i how efficiently plants respond in terms of quantity and quality of produced fruit to the removal of different amounts of generative and/or vegetative tissues and ii whether regeneration ability depends on the time of treatment Total number of fruits and their mean weight were reduced by removal of leaves but germination percentage and rate of germination did not differ from control More vigorous individuals compensated for the loss of tissues to a higher degree and the advantage of being larger increased with severity of the treatment Of 40 plants with umbels completely removed 18 450 regenerated and produced on average 1034 ± 2201 mean ± SD fruits Total fruit numbers and total fruit weight of regenerating plants significantly differed neither among treatments nor from the control but some treatments resulted in poorer germination compared to the control Umbels removed from plants at the beginning of fruit development and left at the locality produced 186 of fruit numbers of control plants and 24 of these seeds germinated Control by removing umbels from plants must ensure that they are collected and destroyed From the management viewpoint there is a tradeoff between later umbel removal resulting in more efficient reduction in fecundity but necessity to handle more developed fruits and early treatment leading to a high regeneration that produces seed of sufficient quantity and very little affected in terms of qualityWe thank Jim Drake for valuable comments on the manuscript especially the idea of metapopulation effect of light seeds and for improving our English The study was supported by the project “Giant Hogweed Heracleum mantegazzianum a pernicious invasive weed developing a sustainable strategy for alien invasive plant management in Europe” funded within the “Energy Environment and Sustainable Development Programme” grant no EVK2CT200100128 of the European Union 5th Framework Programme by institutional longterm research plans no AV0Z60050516 from the Academy of Sciences of the Czech Republic and no 0021620828 from Ministry of Education of the Czech Republic and by the grant of the Biodiversity Research Center no LC06073
