Root sprouting in Rumex acetosella under different nutrient levels

摘要

Growth of Rumex acetosella, a root sprouting plant, was studied in a pot experiment. Each plant of R. acetosella consisted of two ramets which were interconnected by a root about 9 cm long. One of the ramets was placed in a compartment with nutrient-rich soil, the other with nutrient-poor soil. The root connection between the ramets either remained intact or was severed at the nutrient interface after planting. Growth of new roots was prevented at the nutrient interface.
