Abstract

Four applications of ethephon at the concentration of 250-4,000 ppm were applied weekly as soil drench to potted ‘sovereign’ Marigold. The first application was made suddenly after pinching. The result showed that the plants height was decreased respectively when increased the concentration of ethephon. The size of flowers treated with 2,000 and 4,000 ppm decreased slightly and significant differences from the others and delayed flowering about 3-5 days. At these concentrations induced adventitious root along the stem and branches, also caused wide angle of lower lateral branches.
