Description
Impact of benzothiadiazole (BTH) and salicylic acid (SA), as natural defense stimulators, was tested on phenolic compounds biosynthesis in cotton (Gossypium hirsutum L., cv. Y764AG). Cotton leaves were spread with BTH and SA at six concentrations (1.0, 2.5, 5.0, 8.0 and 10 mM) and incubated during 24, 48, 72 and 96 h. Plant-treated with 1.0 mM BTH and 2.5 mM SA, respectively 96 and 24 h of incubation time induced the highest levels of phenolic compounds for each type of stimulator. These both concentrations were then combined for the co-treatment of the plants, with the previous incubation times retained. Results showed that co-treatment with BTH and SA was not beneficial for the induction of phenolic compounds compared to elicitors used alone.
