Seed characteristics of smutgrass (Sporobolis poiretii)

, : Seed characteristics of smutgrass (Sporobolis poiretii). Proceedings, Soil and Crop Science Society of Florida 32: 53-54

S. poiretii, a perennial bunch-type grass native to tropical Africa, is a serious weed in many pastures in S.E. USA. Seed production is continuous from Apr. to Dec., and 29-32 seed heads/plant, with 1432 seeds/panicle, were found on sampling in spring. Germination ranged from 1 to 9% in the field and was increased to >90% by mechanical scarification or treatment with concentrated H2SO4.
