The foliar application of Nod factor [Nod Bj V (C(18:1), MeFuc)] enhanced (P<0.05) the photosynthetic rate of corn; the increases were 36%, 23% and 12% for 10(-6), 10(-8) and 10(-10)M treated plants, respectively. Similarly, lumichrome at 10(-5) and 10(-6)M stimulated the photosynthetic rate of corn plants 1 and 2 days after application. Lumichrome (10(-5) and 10(-6)M) also increased the photosynthetic rates of soybean plants 3 days after treatment. Foliar applications of LCO (10(-6)M) to corn and soybean and of lumichrome (10(-5)M) to soybean increased leaf area, shoot dry mass and total dry mass relative to control plants. However, lumichrome treatments did not affect any growth variable of corn. Results of this study indicate that this signal compound can enhance the photosynthetic rate and growth of plants.
叶面喷施结瘤因子[Nod Bj V (C(18:1), MeFuc)]提高了（P<0.05）玉米的光合速率；对于10(-6)、10(-8)和10(-10)M处理的植株，光合速率分别提高了36%、23%和12%。同样，10(-5)和10(-6)M的核黄素在喷施后1天和2天刺激了玉米植株的光合速率。核黄素（10(-5)和10(-6)M）在处理3天后也提高了大豆植株的光合速率。相对于对照植株，向玉米和大豆叶面喷施LCO（10(-6)M）以及向大豆叶面喷施核黄素（10(-5)M）增加了叶面积、地上部干重和总干重。然而，核黄素处理对玉米的任何生长变量均无影响。本研究结果表明，这种信号化合物可以提高植物的光合速率和促进植物生长。
