Glasshouse studies were carried out to determine the effect of shading on the growth and partitioning of plant
biomass in Paspalum conjugatum Berg. The invidual leaf rate expansion, final leaf are, specific leaf area, and the
whole plant vegetative growth pattern, dry-matter production, leaf area as well as biomass partitioning were
significantly influenced by shading. At the 75% level of shading, P. conjugatum produced the highest values of leaf
weight ratio, specific leaf area and leaf area ratio. Individual leaf assessment revealed that shading
significantly increased the final leaf area, duration of leaf expansion and specific leaf area.
