Title: Effects of growth regulators on growth and flowering in Hippeastrum hybridum hort
Abstract: Soaking of bulbs in 3 concentrations of indoleacetic acid (IAA), gibberellic acid (GA3), 2-chloroethyltrimethyl ammonium chloride (cycocel) or 2-chloroethylphosphonic acid (ethrel) showed various responses on growth and flowering. IAA increased the weight and number of bulblets, GA3 increased bulb weight. Cycocel (1000 mg l−1) increased the number of flowers, while GA3 increased the diameter of the flowers. Application of IAA at 100 mg l−1 and GA3 at 10, 100 or 1000 mg l−1 twice as foliar spray at an interval of 30 days promoted the number of bulblets on the treated plants, while high concentrations of cycocel and ethrel (1000 mg l−1) increased the weight of bulblets. All concentrations of IAA, GA3 and 1000 mg l−1 cycocel increased the number and size of the flowers.
