J. Sheehy ; P. Mitchell ; J. Durand ; F. Gastal ; F. Woodward | 1995Translocation coefficients, computed for unit ground area, are required in crop models as part of the simulation of the partitioning of assimilates. An equation for translocation is derived by considering pressure-driven flow and the physical di[...]

Leaf elongation rate (LER) of grasses depends on N supply and is expressed mostly through cell production, whereas most N in mature leaf tissues is chloroplastic. Our objective was to evaluate a possible competition for N between cell production[...]
