PROBLEM TO BE SOLVED: To provide a method for increasing the production of latex, which improves the productivity of latex in a mature tree (particularly, a young tree) that is said that yield efficiency is low, and can improve the output of the latex in the life of Hevea brasiliensis.SOLUTION: The method for increasing the production of latex includes a step of, with respect to Hevea brasiliensis in one to five years after afforestation, sticking a latex production increase agent, comprising one or more kinds of compounds selected from the group consisting of jasmonic acid and its derivatives as active constituents, to the trunk or stem thereof for ten months to one year and two months before the start of the harvest of latex.COPYRIGHT: (C)2012,JPO&INPIT【課題】収穫効率が低いとされてきた成熟木(特に若年木)におけるラテックス生産性を向上させ、パラゴムノキの生涯のラテックス生産量を向上させることができるラテックス増産方法の提供。【解決手段】植林後1~5年のパラゴムノキ(Hevea brasiliensis)に対し、ジャスモン酸及びその誘導体からなる群から選択される1種以上の化合物を有効成分として含むラテックス増産剤を、ラテックス収穫開始前10ヶ月~1年2ヶ月の間、幹又は茎に付着させる工程を有することを特徴とするラテックス増産方法。【選択図】図1
