Abstract

Two experiments were carried out to determine the effect of gibberellic acid on the longevity of cut flowers of two Zantedeschia elliottiana (W. Wats./Engl.) cultivars: 'Black Magic' and 'Florex Gold'. The flowers were conditioned for 2, 4 and 20 hours in water solutions of 8-hydroxyquinoline citrate at concentrations of 200 mg l-1, and then kept in water and gibberellic acid solutions at concentrations of 50 and 100 mg l-1. Gibberellic acid enhanced the post-harvest longevity of Z. elliottiana flowers. Those of the 'Black Magic' cultivar lasted the longest when not conditioned, but merely stored in gibberellic acid solutions. 8-ydroxyquinoline citrate shortened their longevity by a week. The post-harvest longevity of flowers of the 'Florex Gold' cultivar significantly depended on the concentration of gibberellic acid and conditioning time. The longest-lasting flowers were those conditioned in 8-hydroxyquinoline citrate for 2 hours.
