Abstract: | The effects of salicylic acid (SA) and other phenolic compounds, acetylsalicylic acid (ASA), benzoic add (BA) and sulfosalicylic
acid (SSA), on ethylene production and somatic embryogenesis by carrot (Daucus carota L.) cell cultures were studied. SA and ASA, at concentrations of 10 μM and 100 μM, significantly stimulated somatic embryogenesis
and effectively inhibited ethylene production by carrot cell suspension cultures. The observed increase of embryo number was
proportional to the inhibition rate of ethylene production. However, BA and SSA affected neither ethylene production nor somatic
embryogenesis. The role of SA in somatic embryogenesis is discussed. |
