| Abstract | A 3x3x3 factorial experiment was established to determine the effects of 3 levels of Phosf on, 3 levels of CCC and 3 times of application of GA on growth, flowering and chemical composition of Chrysanthemum morifolium 'Bluechip.' Florida Agricultural Experiment Stations Journal Series "No 22^7 *iFlorida Agricultural Experiment Station, Gainesville. Phosfon and CCC reduced height, while GA increased stem length. CCC reduced fresh and dry weight but Phosfon and GA had no effect. Phosfon had no effect on flower number while CCC and GA reduced the number of flowers. Phosfon increased the time to flowering, but GA cancelled this effect. GA caused a reduction in N, P and K. CCC increased N, P and K but decreased Ca and Mg. Phosfon increased N and P but had little effect on K, Ca or Mg. Table 1.
