This work presents a study of the effect of different phytohormones on growth and accumulation of terpenoid indole alkaloids in a Catharanthus roseus cell suspension culture upon feeding with the precursors loganin and tryptamine. The phytohormones tested were 2,4-dichlorophenoxyacetic acid, salicylic acid, methyl jasmonate and abscisic acid. Among these only methyl jasmonate enhanced the accumulation of alkaloids. Abscisic acid did not enhance the accumulation of alkaloids but delayed the… CONTINUE READING
