Duration of Treatment of Carrot Hypocotyl Explants with 2,4-Dichlorophenoxyacetic Acid for Direct Somatic Embryogenesis.
The relationship between the concentration of 2,4-dichlorophe- noxyacetic acid (2,4-D) and the duration of treatment with 2,4-D on direct somatic embryogenesis from carrot hypocotyl explants was examined. Elevated concentrations of 2,4-D (up to 100 mg/ liter) reduced the duration of pretreatment required for successful embryogenesis.
