Cluster roots
WebCluster-root development was followed by marking very young cluster roots with a basic fuchsin solution and then sampling cluster roots of different stage of development. Swollen regions of harsh hakea lateral roots were identified as future locations for cluster roots. Cluster roots were considered to be 1 d old when the rootlets were just ... Webresults indicate that cluster root exudation led on one hand to direct mobilization and complexation of metals like Al, Fe, and Zn by citrate and on the other hand to the mobilization of soil organic matter which complexes and solubilizes Cu and Pb. Introduction Root exudates can alter the solubility of ions and molecules in the rhizosphere (1 ...
