The effect of frequency-specific sound signals on the germination of maize seeds

OBJECTIVE: The effects of sound treatments on the germination of maize seeds were determined. RESULTS: White noise and bass sounds (300 Hz) had a positive effect on the germination rate. Only 3 h treatment produced an increase of about 8%, and 5 h increased germination in about 10%. Fast-green stain...

Sumario:OBJECTIVE: The effects of sound treatments on the germination of maize seeds were determined. RESULTS: White noise and bass sounds (300 Hz) had a positive effect on the germination rate. Only 3 h treatment produced an increase of about 8%, and 5 h increased germination in about 10%. Fast-green staining shows that at least part of the effects of sound are due to a physical alteration in the integrity of the pericarp, increasing the porosity of the pericarp and facilitating oxygen availability and water and oxygen uptake. Accordingly, by removing the pericarp from the seeds the positive effect of the sound on the germination disappeared.
