用国产乙烯利处理分属四科的五种植物:巴西三叶橡胶树(Hevea brasiliensis,大戟科),印度紫檀(Pterocarpus indicus,豆科),吐鲁香(Myroxylon balsamum,豆科),漆树(Rhussp,漆树科),马尾松(Pinus massoniana,松科),从树干采割乳液(胶乳,树脂等)。处理植株乳液排泌量明显地大于对照。看来乙烯利(乙烯)促进植物排泌乳液的现象具有一定的普遍性。本文还讨论了乙烯利在刺激植物排泌乳液中可能起的作用。 Five domestic plants belonging to four families were treated with domestic ethephon: Hevea brasiliensis (Euphorbiaceae), Pterocarpus indicus (Leguminosae), Myroxylon balsamum (Leguminosae), Rhus spp. Rhussp), Pinus massoniana (Pinus massoniana), harvesting lotions (latex, resins, etc.) from the trunk. Excretion of treated plants was significantly greater than the control. It appears that ethephon (ethylene) promotes the phenomenon of plant excretion of milk has a certain degree of universality. This article also discusses the possible role of ethephon in stimulating plant excretion emulsions.
