| Abstract | ||
| This study was carried on Dahlia hybrida cv. Edinburgh, to compare two propagation methods, application of paclobutrazol PBZ at 0, 10 and 20 mg/liter and micronutrients at concentrations 0, 0.25 and 0.50 g/liter on tuberous roots growth. The results can be summarized as follows: The plants propagated by tuberous roots gave significant increase in roots number, fresh and dry weight and specific weight. But tuberous roots of plants propagated from cuttings contained higher percentage of Inulin 13.33 and 9.95% dry weight for two seasons, respectively. Tuberous roots taken from plants treated with 20 mg/liter PBZ gave largest number of tuberous roots and heaviest fresh weight, in addition to Inulin percentage. | ||
