WebAug 10, 2013 · Cluster-root formation is influenced mostly by P concentration ( [P]) in shoots (Shane et al. 2003 ), which also affects the induction of physiological and biochemical processes that allow the solubilisation and uptake of nutrients (Shane and Lambers 2005a ). During the formation of these roots, a great number of branch roots …
WebApr 4, 2011 · Cluster root system development is highly plastic and affected by the deficiency of several nutrients. Among these factors, P deficiency appears to be the most important element determining cluster root formation in white lupin (Gardner et al., 1983; Dinkelaker et al., 1995; Johnson et al., 1996). Both local (external P) and systemic … WebPlants with cluster roots gain access to fixed and organic phosphate through an increase in surface area and release of phosphate-solubilising exudates. Hence plants with cluster roots grow faster on phosphate-fixing soils than species without clusters. Cluster roots have a distinct morphology.
