Resprouting after disturbance in the short-lived herb Rorippa palustris (Brassicaceae): an experiment with juveniles

Popis výsledku v původním jazyce

The impact of plant age, severity of injury and nutrient levels on the resprouting from roots was experimentally assessed in juveniles short-lived herb Rorippa palustris. In a chamber, six cohorts of young plants were injured to obtain the threshold agefor the ability to resprout from roots: injured individuals older than 5 weeks were able to resprout, but not plants younger than 3 weeks. The impact of injury severity and nutrient levels on resprouting ability was assessed on juveniles in a greenhouse.Injury induced growth of new shoots from root buds, while the number of adventitious buds on roots was not influenced by injury. Both injury treatments had a similar effect in this respect. The number of new shoots produced after injury was higher at the high nutrient level, but the number of formed adventitious buds on roots was not influenced by nutrient level. Nutrient level also influenced the amount of regenerated biomass, but the extent of regeneration was not influenced
