WebConceptually, root phenology can be characterized by several alternate patterns of root production (Fig. 1). Concentrated patterns in root production may occur where resources are available during a single seasonal pulse, whereas bimodal patterns could occur in response to multiple periods of favorable environmental condi- tions.
