Duration of Treatment of Carrot Hypocotyl Explants with 2,4-Dichlorophenoxyacetic Acid for Direct Somatic Embryogenesis

Abstract

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. © 1996, Taylor & Francis Group, LLC. All rights reserved.
