The objective of this study was to evaluate the phytomass accumulation in cut chrysanthemum, var. Salmon Reagan, at different phenologic phases, in greenhouse environment, in Goiás State, Brazil. The experiment was carried out in two periods, from May to August (winter), and from October to January (summer), 2003/2004. The population density was 80 seedlings.m-2. The experimental design was a complete randomized, with plots split in time, with four replications. The plant portion (stems, leaves, and inflorescences) factor was applied to plots and the development phases (45, 60, 75, 90, 105, and 120 days) applied to the sub-plots. The plant accumulated more phytomass (leaves, stems, and inflorescences) in the winter than in the summer period. In the winter, the phytomass accumulation decreases from stems to leaves and to inflorescences, whereas in the summer it decreases from leaves to stems and to inflorescences. KEY-WORDS: Ornamental plant; dry matter; cut flower.
