Abstract

Various plant physiologic properties of sodium 2,3:4,6-di-O-isopropyli-dene-2-keto-L-gulonate (ISO accepted common name: dikegulac) were investigated on a number of bioassay systems. Dikegulac retarded growth of wheat, pea, and Avena fatua. This effect could be overcome by GA3. The growth of tomato callus was retarded at lower concentrations and completely inhibited by higher concentrations of dikegulac. This effect was counteracted by GA3 and, at certain rates, dikegulac even promoted the growth stimulation activity of GA3. Parthenocarpic fruit set of pears was stimulated by dikegulac. Apical dominance was suppressed in Poa pratensis, Lolium perenne, and azalea, interactions with indole-3-acetic acid (IAA) and kinetin were seen in azalea. Translocation was studied on chrysanthemum. Dikegulac is the active ingredient of a new growth regulator (trade name: Atrinal-trademark of Dr. R. Maag Ltd., CH-8157 Dielsdorf, Switzerland) that is used as a pinching agent for ornamentals and as a growth retardant and branching agent for hedge plants.
