A trial was carriedout in green-house to estimate morphogenic traits and growth indices of Mombaçagrassdevelopment. Three growths were considered: the seminal, establishment growth(G1) and the regrowths following a clipping taken on the 16th (G2)and 37th (G3) days of the seminal growth. The variables assessedwere the growth indices: relative growth rate (RGR), net assimilation rate (NAR),leaf area ratio (LAR), and the rates of leaf appearance, elongation, expansionand senescence. Accordingly, harvests were taken at the ages of: 13, 20, 27,42, 55, 69 and 83 day of the seminal growth (G1); 0, 3, 6, 10, 17, 24, 38, 52and 66 day of the 2nd regrowth (G2) and 0, 1, 3, 7, 21, 35, 49, 63and 77 day of the 3rd growth (G3). There were three replications(pots) per treatment in a completely randomized design. Figures for NAR, LARand RGR were high during early seminal growth but declined assynthotically asplant aged. Initial values for these indices were higher in the seminal growthas compared to the 2 regrowths. Cutting taken on the 37th day ofthe seminal growth hindered the initial growth of the plants regarding leafappearance and elongation rates, LAR, NAR and RGR. The latter two indices whichhad negative values during early regrowth, were recovered by the 16thregrowth day.
