Seeds of exotic morningglories can be completely killed by torching and subsequent water immersion

Abstract

種子の乾熱処理および火炎放射処理が帰化アサガオ類(ホシアサガオ(Ipomoea triloba),マメアサガオ(I. lacunosa),マルバアサガオ(I. purpurea),マルバアメリカアサガオ(I. hederacea var. integriuscula)およびマルバルコウ(I. coccinea))の発芽に及ぼす影響と,火炎放射後の湛水が種子の生存に及ぼす影響について調査した。80°Cで30分間乾熱処理した場合,5草種の発芽率(吸水,膨潤した種子の割合)は21.1∼97.8%であった。マメアサガオ(21.1%)とマルバアサガオ(47.8%)を除く3草種は,72.2∼97.8%と高い発芽率を示した。一方,火炎放射処理を3秒間行った場合,発芽率は94.4∼100.0%と5草種ともほぼ完全に発芽した。さらに火炎放射処理後の種子は湛水条件下に2ヶ月間埋土されることにより,5草種全てにおいて100%死滅することがわかった。本研究より帰化アサガオ類の防除において,種子散布後に圃場地表面を火炎放射処理し,その後湛水することが有効であることが示唆された。
