Greenhouse studies conducted in 1990 and 1991 evaluated the influence of dikegulac and benzyladenine on frond initiation and vegetative growth of Boston fern [Nephrolepsis exaltata (L.) Schott `Compacta']. Four weeks after transplanting, fern liners were sprayed with aqueous solutions of dikegulac (0, 250, 500, or 750 mg·L–1) or benzyladenine (BA; 0, 50, 100, or 150 mg·L–1). The effect of dikegulac and BA on the number of shoots, frond length, leaf area, and dry weight was measured. Dikegulac stimulated shoot initiation and increased leaf area and dry weight without affecting frond length. BA reduced frond length and had no effect on shoot initiation and dry weight. This study suggests dikegulac has potential to improve the appearance and aesthetic quality of Boston fern. Chemical names used: 2,3:4,6-bis-0-(1-methylethylidene)-α-l-Xylo-2 hexulofuranosonic acid (dikegulac); N-(phenylmethyl)-1H-purine-6-amine (benzyladenine).
