Abstract

The present study was conducted to assess the morphological response of onion plants to different GA₃ levels (0, 20, 40 and 60 ppm). The factor levels of GA₃ were applied during transplanting by root soaking and foliar spray at 30 and 60 days after transplanting. The gibberellic acid had a great effect on increasing plant height (46.50 cm), shoot biomass (641.67 g m^-2), bulb biomass (1125.00 g m^-2) and also dry matter accumulation in onion plants under the effect of 60 ppm compared to control. Plants grown up without GA₃application were shorter than those grown with GA₃spray where the lowest plant height (34.67 cm) was remarked. The leaf number (11.43) was considerably increased when 60 ppm GA₃ was used as the growth promoter factor in comparison to control. The plants attain minimum fresh biomass at harvesting time in the shoot (441.67 g m^-2) and bulb (641.67 g m^-2) grown in control plot. Considerably (41.63%) more dry shoot biomass accumulation was recorded in 60 ppm GA₃ treated plants in comparison with the control at harvesting stages. Insignificant effect by all concentration of GA₃ was found in bulb length, fresh root biomass and dry root biomass. Thus, the use of 60 ppm GA₃can be recommend for onion production due to the significantly increased of the fresh bulb biomass with about 42.96% over control.
