Chemical solution is an efficient method to induce the formation of 2-(2-phenylethyl) chromone derivatives in Aquilaria sinensis

In this study, mechanical wounds, fungal elicitors and salt solution were applied to induce the formation of 2-(2-phenylethyl) chromones, which are the principal compounds in agarwood. In this research, chemical solution was the best inducer that could induce Aquilaria sinensis calli to produce the highest amount of chromones E and M at 79.20 and 41.62μgg−1, respectively. Chemical solution was then applied on three-year-old saplings by transfusion to verify its induction effect. Chromones E and M were detected in treated saplings after 15 d and then increased with increasing pruning time; their contents reached 22.05 and 3.42μgg−1, respectively. Our results suggested that chemical solution was the most promising chemical inducer for agarwood production on the industrial scale. Graphical abstract
