Increasingly, cultivation of teak is experiencing problems of pressure of pathogens in Côte d'Ivoire; This will affect quality of wood and disappearance of certain plantations in future. Objective of present work is to study one of natural defenses of plants, synthesis of phenolic compounds. Leaves of teak plants were treated with salicylic acid and chitosan separately and simultaneously; and amount of phenols was evaluated. Results showed that these elicitors amplify synthesis and accumulation of phenols. In treated leaves, high values were recorded with salicylic acid (81.07 mg tyrosin / gFM), followed by salicylic acid + chitosan treatment. But accumulation was earlier with chitosan, 12 hours after treatment. Basal and apex leaves also responded to treatment with phenol synthesis. Phenol content of leaves after treatment was more dependent on elicitors than phyllotaxy. However, cumulative action of salicylic acid and chitosan on synthesis and accumulation of phenols follows effect of chitosan.
