Challenges in research on rhizomatous clonal plants

doi:10.11686/cyxb2021424

Abstract

Abstract:

Rhizomatous clonal plants are a category of clonal plants in which daughter ramets are formed by spreading underground stems. Their particular distinction of having a subsurface connection system provides them a range of unique reproduction and growth modes and also unique adaptations to their local environment. However， because relevant research techniques are not well developed， the differences between rhizomatous and other clonal plants in phenotypic plasticity， clonal integration， foraging behavior and clonal division of labor， are not yet well understood and the potential to harness their behavior to prevent weed invasion， to mitigate climate change， to reduce ecosystem degradation or to promote ecosystem ecological restoration is also unclear. In view of this， through a review and summary of relevant recent research， we have identified knowledge gaps for further research. We recommend immediate research effort in the following areas： 1） Innovation in research methodology for identification and selection of beneficial plasticity traits； 2） The mechanisms by which various environmental factors affect clonal integration outcomes； 3） Development of a complete foraging model that comprehensively combines plant and environmental characteristics.

Key words: rhizome, plasticity, trait, clonal integration, foraging model
