Young plants of the Impatiens walleriana 'Spellbound Lilac' and 'Spellbound Pink Imtrarepu' were sprayed with GA3 at the concentrations of 0, 10, 30, 50, 100 and 150 mg/cubic dm. Measurements of the plants length of main and lateral shoots and the number of buds and flowers were carried out two weeks after application of gibberellic acid. Gibberellic acid forced plant development. After the application of GA3 the main and lateral shoots were much longer. Under the influence of GA3 plants were flowering more abundantly. In case of GA3 the number of buds and flowers increased by 57.4-87.8 percent in comparison to control plants. In the case of GA3 the number of buds and flowers increased by 57.4-87.8 percent in comparison to control plants. However, gibberellic acid had an adverse effect on the appearance of plants and resulted in low chlorophyll content in leaves
