The influence of selected growth regulators on development, decorative value and yield of corms of Easy Pot freesia (Freesia Eckl. ex Klatt). Part I. Gibberellin A3

Abstract: Freesias of Easy Pot group are very interesting complement to an assortment of flowering potted plants. However , there is a lack of information about their requirements and cultivation methods. Experiments were carried out in the years 2006–2007 in the unheated plastic tunnel. Cormlets of three cultivars: ‘Gompey’, ‘Popey’ and ‘Suzy’ were the plant material. Corms were soaked in solution of gibberellic acid in concentration of 10, 20, 40, 80 or 160 mg dm-3 for 24 hours just before planting, in a dark room with air temperature 28–30oC. Corms soaked in water were served as the control. During the vegetation season measurements of vegetative and generative traits of plants were conducted. After the end of vegetation period, coefficients of corm weight and number increase were calculated. It was found that cormlets of Easy Pot Freesia can be recommended for cultivation in pots. Cultivar had a significant effect on vegetative and generative parameters of plants. Among evaluated cultivars ‘Gompey’ was characterized by the greatest decorative value. Plants of this cultivar had the longest inflorescence shoots with the greatest number of lateral shoots and the greatest number of flowers. Irrespective of cultivar, gibberellic acid increased plant height, total number of leaves, length of inflorescence shoots and decreased flower diameter. The use of gibberellic acid increased weight of the offspring corms. Among evaluated concentrations the highest effect was noted for 160 mg dm-3. However, used in the experiment growth regulator did not affect number of obtained new corms.
