Abstract
Vitex agnus castus is Mediterranean native plant with blue or pink aromatic flowers.
The potential of introducing Vitex agnus castus as a commercial native ornamental pot plant has been examined.
To lead the natural structure into a uniform and compact flowering plant, 500, 1500 and 2500 mg.
L-1 daminozide (Alar) and chlormequat chloride (CCC) were applied once or twice, at a two-week intervals.
Visual quality characteristics such as plant height and diameter, stem length and thickness, internode length and flowering were determined 6 weeks after treatment.
Double application at low concentration was more effective that a single application at high concentration.
Overall CCC was more effective than alar.
The observed maximum height reduction was approximately 25 cm compared to control, and it was achieved by a double application of 2500 mg.L-1 CCC. Height reduction was related to the reduction of internode elongation and not to a decrease in the number of nodes.
The largest plant diameter (i.e. approximately 30 cm larger than the control) was obtained for plants sprayed twice with 1500 mg.L-1 of CCC. The highest number of flowers was given by the double application of CCC at 1500 mg.L-1. Results from this study indicate that Vitex agnus castus has the potential for use as a flowering pot plant.
