It has been well known that vegetation under the Japanese red pine trees was very sparse. This phenomenon was contributed to allelopathic substance related from fallen leaves, bark or pinecones. Some allelochemicals released to the phenomenon have already been isolated from the extracts of fallen leaves or bark. In pre-observation of the Japanese red pine forest, we found that the fewer weeds in the ground with many pinecones grow than that in the ground without pinecones. In this study, we investigated the allelopathic substance released from pinecones, since to our knowledge allelopathy of pinecones has not yet been studied. The exudates of the pinecones showed high biological activity. When some species of germinating seeds were cultured with pinecones, the growth of the plants was inhibited. These results suggested that some substances released from the pinecones play some roles as allelochemical(s) in Japanese red pine trees. The isolation and the identification of the substances are under study.
