    Adventitious sprouting from the hypocotyle and roots in monocarpic herbs has been confirmed in previous experimental studies as a way how to avoid bud limitation after severe injury in annual and biennial plants. Data about the role of adventitious sprouting in natural populations, however, were missing. The aim of our study was to assess whether adventitious sprouting occurs in natural populations and how it is affected by plant size, plant injury, plant cover and environmental characteristics. Data were sampled on 14 037 plant individuals from 389 populations belonging to 22 species of annual and biennial plants. We measured certain growth parameters in plant individuals, evaluated species composition and plant cover in communities, and estimated environmental characteristics using Ellenberg indicator values. We confirmed that adventitious sprouting occurs in natural populations of all but five species examined in the present study.
