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

Abstract

ObjectiveThe effects of sound treatments on the germination of maize seeds were determined.ResultsWhite 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.

Germinación Y Vigor De Semillas De Poblaciones De Maíz Con Diferente Proporción De Endospermo Vítreo

“…El peso de pericarpio varió entre 0,016 y 0,030 g, encontrándose poblaciones con porcentajes mayores al 5% de pericarpio, como la población 22, lo que es importante, debido a que el pericarpio es la parte del grano que tiene elevado contenido de fibra cruda (Nuss y Tanumihardjo, 2010). Por otra parte pericarpios gruesos influyen en forma desfavorable en la fisiología de la semilla y en el establecimiento temprano del cultivo (Vicient, 2017), por un probable retraso en la imbibición por la interferencia física de la protusión de Tabla 3. Comparación de medias para las variables estructurales de granos de 35 poblaciones de maíz criollo de la región Grijalva, estado de Tabasco, México.…”

The Effects of Sounds and Music on Cells and Organisms: A Promising and Developing Area of Research

“…In plants, sound waves can influence germination, development and growth (Qin et al 2003, Mishra et al 2016, Vicient 2017. It can also enhance the immunity increasing tolerance to drought (Chivukula and Ramaswamy 2014, Choi et al 2017, Lopez-Ribera and Vicient 2017.…”
