Resumo
The objective of this study was to evaluate P
accumulation in cut chrysanthemum, var. Salmon Reagan, at
different phenologic phases, in the winter. The experiment was
carried out in greenhouse environment, in Goiás State, Brazil.
The population density was 80 seedlings.m-2. The experimental
design was completely randomized, with plots split in time, and
four replications. The plant portion factor (stem, leaf,
inflorescence and whole plant) was applied to plots, and the
development phases (45, 60, 75, 90, 105, and 120 days) applied
to sub-plots. The plant nutrition was 133 g.m-2 of
thermophosphate Yoorin and 150 g.m-2 of fertilizer formula
5:25:15, which was added to the circulating nutritive solution of
calcium nitrate (20 g.m-2), during all the evaluated period,
alternated with potassium sulfate (30 g.m-2) and potassium nitrate
(30 g.m-2), each fifteen days. It was concluded that P demand by
chrysanthemum, during the growing cycle, ranges according to
the plant age and the organ studied, having been more accentuated
in the stems and between 90 and 120 days after sowing.
