Abstract

“The Infusion Technique” is a relatively effective method to induce agarwood formation in Aquilaria sinensis trees, while there are many defects in the existing transfusion devices, inducers and procedures. Our study evaluated a novel Modified Kit for “the Infusion Technique”, which is developed on five Chinese patents, including the plant transfusion needle and vessel, inducer and procedure (for primary and secondary whole tree agarwood-inducing process). The plant transfusion needle prevent the transfusion fluid from oozing out of the trunks, thus improve infusion efficiency. The transfusion vessel make the clogging in transfusion needles or tubes easily detected , then quickly handled. By adopting Modified Kit, the agarwood was formed in the whole Aquilaria trunks at the three-month after treatment, the average ASEC (Alcohol Soluble Extractive Content) in all agarwood obtained at the six-month met Chinese Pharmacopoeia standard, and reached the peak value of 43.9% at the 16-month. These results indicate that the Modified Kit contributes to improve the quality of agarwood and shorten the Production Period.
