Abstract

The effect of rising concentrations of indolbutyric acid (IBA) solutions was evaluated with different exposition times in stem cuttings of Chrysanthemum morifolium cv. White Reagan 606. The applied concentrations were 0,500,1000 and 1500 ppm of IBA during 5s, 1h and 2h, in a randomized complete split-plot block design, with IBA concentrations as main treatment. The experiment was installed in styrofoam trays in a green-house with a mist device and vermiculite as substrate. Transplanting time was determined by an additional block. All treatments induced rooting even in the absence of IBA. In a general sense the fastest treatments tended to be the more efficient when combined with higher concentrations.
