| 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 vegetative growth. The results can be summarized as follows: The plants propagated by tuberous roots gave higher values for plant height, stem diameter and shoot number when compared with plants propagated by cuttings, for two seasons, respectively. Spraying plants with PBZ at 20 mg/liter significantly increased stem diameter and shoot number when compared with untreated control. Fertilization with any concentrations micronutrient caused a significant decrease in plant height. But stem diameter, shoot number and chlorophyll content significantly increased at concentration 0.50 g/liter. In general, plant propagated by tuberous roots which sprayed with 20 mg/liter PBZ and 0.50 g/liter micronutrient gave a higher values for stem diameter, shoot number, stomata number on lower leaf surface. | ||
