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.
目的
确定声音处理对玉米种子萌发的影响。
结果
白噪声和低音（300赫兹）对发芽率有积极影响。仅3小时的处理使发芽率提高了约8%，5小时的处理使发芽率提高了约10%。固绿染色表明，声音的影响至少部分是由于果皮完整性的物理改变，增加了果皮的孔隙率，促进了氧气供应以及水分和氧气的吸收。因此，去除种子的果皮后，声音对发芽的积极影响消失了。
