Relationship between the structure of root systems and resource use for 11 North American grassland plants (2003, unknown): “…coarse belowground biomass should be less directly responsible for resource acquisition than placing fine roots in deeper pools of soil water while economically transporting large amounts of water, storing carbohydrates and mineral nutrients, or supporting vegetative reproduction (Fitter 1996).”
Fractal analysis on root systems of rice plants in response to drought stress (2009, background): “The architecture of the root system is also well known to be a major determinant of root functions in the acquisition of soil resources such as nutrients and water (Lynch, 1995; Yamauchi et al., 1996; Fitter, 2002; Wang et al., 2006).”
Root Phenotyping for Drought Tolerance: A Review (2018, background): “Fine roots are most permeable and thought to have greater ability to absorb water, especially in herbaceous plants [54].”
Nitrate and phosphate availability and distribution have different effects on root system architecture of Arabidopsis. (2002, background): “The nitrate-dependent changes are reminiscent of a herringbone structure (long primary root with low lateral root density) that optimise resource allocation and nitrate capture in a volume of soil (Fitter, 1991; Robinson, 1996).”
