Compensation of seed production after severe injury in the short-lived herb Barbarea vulgaris

Popis výsledku v původním jazyce

Plants of B. vulgaris were cultivated in a three-year garden experiment at two nutrient levels (high vs. low). During the experiment, two levels of injury severity were applied: high (removal of all aboveground biomass) and low (removal of aboveground biomass leaving basal axillary buds intact). Damage was applied at four life-cycle phases: young rosette, overwintered rosette, flowering plant, fruiting plant. All injured plants survived and resprouted irrespective of life-cycle phase, severity of injuryand nutrient availability. Injury significantly affected seed production and also the plants? life-cycle. Nutrient level only marginally affected resprouting after injury and seed production. The experiment showed that the ability to sprout from roots enables plants to survive a 100% loss of aboveground biomass, and to keep some seed production or even compensate it. The short-lived ruderal species Barbarea vulgaris successfully copes with severe disturbance by resprouting and does not
