Effect of gibberellic acid on the quality of chrysanthemum (<i>Dendranthema grandiflora</i> L.) cv. Faroe

Abstract

The aim of the present work was to evaluate the quality of chrysanthemum cultivar Faroe, subjected to different gibberellic acid (GA₃) concentrations applied to the field. The treatments were composed of four doses of GA₃ (0, 15, 30 and 45 mg L^-1) applied at the beginning of the formation of buttom floral (28 days after transplanting of seedlings). According to the results, a single low concentration of GA₃ application did not interfere with the phenotypic characteristics of the chrysanthemum cultivar Faroe.

Key words: Dendranthema grandiflora, height, diameter, flowering.
