Nodulated soybean roots produced more ethylene and contained more 1-aminocyclopropane-1-carboxylic acid than uninoculated roots. Nodules produced more ethylene and contained more 1-aminocyclopropane-1-carboxylic acid per gram of material than roots. Almost all of the ethylene produced by the nodules was produced by the plant fractions of the nodules. Ethylene, at physiological concentrations, did not inhibit nodulation in soybeans.
结瘤大豆根比未接种根产生更多的乙烯和含有更多的 1-氨基环丙烷-1-羧酸。每克材料的根瘤产生的乙烯和含有更多的 1-氨基环丙烷-1-羧酸比根瘤多。几乎所有由根瘤产生的乙烯都是由根瘤的植物部分产生的。在生理浓度下,乙烯不会抑制大豆的结瘤。
