Abstract
The objective of this work was to evaluate the influence of indole acetic acid (IAA) on fresh weight of cuttings and in the rooting of goldenrod. The first experiment was arranged in randomized blocks in factorial scheme 5 x 3, and 5 doses of IAA at 0, 500, 1000, 2000 and 3000 mg/L and three evaluation periods (7, 14 and 21 days after staking-DAS) with six replications. The second experiment was also established in randomized blocks in factorial scheme 4 x 2, with 4 class of fresh weight (0.5-0.7, 0.71-0.9, 0.91-1.10 and greater than 1.10 g) in the presence or absence of indol butyric acid (IBA) and two evaluation periods (14, 21 days after staking), with six replications. In both experiments, the stakes were standardized to 5 cm. In the first experiment the stakes were 1 cm from its base immersed for 30 seconds in different water-alcohol solutions of IAA, while the second base of the cuttings were immersed in water, and then the powder containing 2000 mg/kg of IBA, and subsequently placed for rooting in trays with 256 cells (45 mL). Number of roots/cutting, rooting and survival of seedlings were determined. The presence or absence of IAA or IBA does not affect the rooting of cuttings and even the survival of seedlings. There was no effect on rooting cycle suggesting that the dosage is 2000 mg/L of IAA, because it provided higher number of roots/cutting, while the increase in fresh weight of cuttings provided to increase the number of roots/cuttings.
