The evaluation of Pedilanthus palmeri Millsp. as a potential interior landscape plant

Newman, Dara, 1962- January 1988 (has links)
Pedilanthus palmeri Millsp. was evaluated as a potential interior landscaping plant. The optimal propagation technique, production and post-production light requirements, growth regulator response and photoperiod requirement were analyzed. Cuttings were successfully rooted within five weeks after treatment with aqueous solutions of IBA. Root fresh weight increased from 0.58 g with 0 mg·liter⁻¹ IBA to 1.12 g with 6736 mg·liter⁻¹ IBA. No difference in leaf length, width or thickness, plant height or node number was found between plants grown under 77% and 88% shade. Plants moved to a low light interior environment continued to grow and new, thin leaves replaced abscised leaves. The optimum concentration of the growth retardant Bonzi (paclobutrazol), 0.125 g ai per pot, caused a 46% reduction in shoot height. Apical pinching and 500 mg·liter-1 BA increased branch number 3.8-fold. Pedilanthus palmeri is a short day plant. Flowering occurred in the 8 and 10 hour light treatments but not in the longer photoperiods.
