Proceedings of the Second     International Weed Control Congress. (41) American Journal of Botany 87(9):     1279-1286. Success of segment regeneration is determined by the original location of the segment on the rhizome, including proximity to, or inclusion of, axillary and apical buds, as well as environmental conditions (Holm et al., 1977; Wilcut et al., 1988a; Gaffney, 1996; English, 1998). 6). It is the only vetivergrass recommended by NRCS and land-grant universities for use in the NRCS Pacific … P. RAHATE, SARANYA T.S. B. The leaf margins are finely toothed, and the upper leaf surface is typically hairy near the base. Cogon grass rhizomes exhibit apical dominance (English, 1998), which may be an important factor both in limiting the local spread of cogon grass via rhizomes (Wilcut et al., 1988a), and reducing the efficacy of herbicidal control due to sub-lethal herbicide sink activity in dormant axillary buds (Shilling et al., 1997; English, 1998). • Effect on Ovarian Activity and Estrus Behavior / Gavage / Roots: Study evaluated the effect of short-term gavage of ethanolic extract of Imperata cylindrica root on ovarian activity and estrus behavior of female mice.
