Abstract

Twelve tropical grass accessions were evaluated to determine the effect of clipping height and burning on regrowth. Regrowth in the dark (regrowth potential) was not correlated with regrowth or relative growth rates during the first three weeks after clipping in 11 accessions. Residual leaf area and residual dry matter were correlated with relative growth rates and with total regrowth during the same period. The shape of the curves of dry matter accumulation with time differed in stoloniferous and caespitose accessions.
