Abstract: Plant rhizosphere growth-promoting bacteria can promote plant growth, and the volatile components produced by the flora play an important role. 3-methyl-1-butanol, i.e. isoamyl alcohol, is a common volatile organic component of microorganisms. However, the effect of 3-methyl-1-butanol on seeds germination and the growth of higher plants is still unknown. In this paper, the effects of three concentrations(1, 10 and 100 mg·L-1) of 3-methyl-1-butanol on the germination of wheat and maize seeds were studied. Two contents of 1 and 10 mg·L-1 of 3-methyl-1-butanol increased the vigor index of maize and wheat seeds; under low contents of 3-methyl-1-butanol treatment, the content of soluble sugar and soluble protein in maize and wheat seeds decreased, while the SOD activity and chlorophyll content in germs increased significantly compared with the control group. Therefore, 3-methyl-1-butanol can promote maize and wheat growth at appropriate concentrations.
