Hypothesises that 4 mechanisms of boron-tolerance exist: 1. a physical barrier at xylem loading that also, 2., may include an efflux system; 3. enhanced sugar levels in shoot and root and 4, maintaining or increasing root biomass in the upper soil depths where the concentrations of boron are not toxic. / Thesis (Ph.D.)--University of Adelaide, School of Earth and Environmental Sciences, Discipline of Soil and Land Systems, 2004
