IAA, NAA, 2, 4-D and dicamba induced ethylene production while quinclorac did not. But the activity of quinclorac for promoting hypocotyl elongation was comparable to that of IAA. Fenac, though it has been classified as a hormone type herbicide, neither induced ethylene production nor promoted hypocotyl elongation. These results suggest that different modes of actions may exist among herbicides which have been classified as hormone-type."},{"@value":"ホルモン型除草剤と分類される一群の除草剤がある。これらの除草剤は, 種々の生物検定法に於いてIAAと同様にオーキシン活性を示すが,その詳細な作用機構は不明である。そこで, 種々のホルモン型除草剤の作用メカニズムを明らかにする為, 同一の生物材料を用い, 二つの生物検定法でホルモン型除草剤の活性を調べた。生物検定法には, 薬剤によって誘導されるエチレンを指標にしたエチレン発生試験と, 生長促進を指標にしたスリット試験を用い, ヤエナリ下胚軸を生物材料とした。<br>まず, 本研究に用いた薬剤のヤエナリの生長に及ぼす影響について調べたところ, 10<sup>-6</sup>～10<sup>-4</sup>Mで,すべての供試化合物が下胚軸の伸長を抑制し, 2, 4-D, dicamba が最も強い活性を示した (Fig. 2)。次にエチレン発生試験およびスリット試験における活性を調べた。IAA, NAA, 2, 4-Dおよび dicamba は, ヤエナリ下胚軸のエチレン発生を誘導したが, quinclorac および fenac はエチレン発生を誘導しなかった (Fig. 5)。しかしスリット試験においては, quinclorac はIAAとほぼ同等の活性を示した。また fenac はスリット試験においても活性は認められなかった (Fig. 6)。以上の結果により, 同じホルモン型除草剤に分類される薬剤でも, その作用機構は異なることが示唆された。"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282679255733506","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254836457"}],"foaf:name":[{"@language":"en","@value":"MITO Nobuaki"},{"@language":"ja","@value":"水戸 信彰"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Agricultural Science Research Laboratory, Takarazuka Research Center, Sumitomo Chemical Co., Ltd."},{"@language":"ja","@value":"住友化学 宝塚総合研究所"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001204279023873","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254835832"}],"foaf:name":[{"@language":"en","@value":"YOSHIDA Ryo"},{"@language":"ja","@value":"吉田 亮"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Agricultural Science Research Laboratory, Takarazuka Research Center, Sumitomo Chemical Co., Ltd."},{"@language":"ja","@value":"住友化学 宝塚総合研究所"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679255733504","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254836459"}],"foaf:name":[{"@language":"en","@value":"OSHIO Hiromichi"},{"@language":"ja","@value":"大塩 裕陸"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Agricultural Science Research Laboratory, Takarazuka Research Center, Sumitomo Chemical Co., Ltd."},{"@language":"ja","@value":"住友化学 宝塚総合研究所"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"0372798X"},{"@type":"EISSN","@value":"18824757"},{"@type":"CODEN","@value":"ZASKAN"}],"prism:publicationName":[{"@language":"ja","@value":"雑草研究"},{"@language":"en","@value":"Journal of Weed Science and Technology"},{"@language":"en","@value":"J.
