Goldenrod is a popular filler for flower arrangements and bouquets. This study was conducted to determine the effects of foliar treatments of gibberellic acid (GA3) and paclobutrazol (PBZ) on the growth and flowering characteristics of goldenrod (Solidago x hybrida cv. 'Tara') grown under open field conditions. Beginning from 30 days after planting, GA3 at a concentration of 250 mg L-1 was sprayed on plants 0 times (control), once and twice at one-week intervals, and again 30 days after planting, PBZ at concentrations of 125, 250 and 500 mg L-1 was sprayed on plants once. The stem length was 68.51 cm in the control, while it was 78.61 cm and 83.33 cm in the plants treated once and twice with GA3, respectively and 60.17 cm, 55.38 cm and 50.71 cm in the plants treated with 125, 250 and 500 mg L -1 of PBZ, respectively. The number of secondary inflorescences per stem was 29.70 and 31.43 in the plants treated once and twice with GA 3, respectively and 21.96 in the control, whereas it ranged from 20.07 to 20.67 in the PBZ treatments. The number of stems per plant was 0.94 in the control, 1.45 and 1.62 in the plants treated once and twice with GA 3, respectively and ranged from 0.83 to 0.91 in the PBZ treatments. With respect to almost all characteristics, the best results were recorded in plants treated once and twice with GA3. © 2010 EuroJournals Publishing, Inc.
