Weeds that can do both tricks: vegetative versus generative regeneration of short-lived root-sprouting herbs Rorippa palustris and Barbarea vulgaris

Popis výsledku v původním jazyce

Weeds of arable land have two strategies for coping with severe disturbance: they have either a very short life cycle and survive disturbance events (ploughing) as seeds or they rely on an underground bud bank and a large regeneration capacity from fragmented roots or stems. Representatives of the respective strategies differ in their investments: annual weeds invest in generative structures and production of easily dispersable or durable seeds, whereas perennial weeds invest preferentially to underground storage organs bearing buds which serve for vegetative propagation. Even when perennial weeds may also produce seeds under favourable conditions, these may serve for further field infestation and spreading. However, the ability of some short-lived annual weeds to regenerate from roots is often overlooked in studies on mechanisms for disturbance survival. Here we show that short-lived weeds capable of adventitious sprouting from roots may be very successful in vegetative regeneration f
