Abstract

A method of enhancing the germination of seed by immersing the seed in an aqueous solution including dissolved inert gas and sonicating the seed at a frequency preferably of between about 15 kHz and about 30 kHz and an energy density of between about 1 watt/cm2 and about 10 watts/cm2 for a period of between 1 minute and about 15 minutes. The sonicated seed exhibits enhanced germination by a reduction in the time required for germination, an increase in the percentage of total seeds that germinate, and an increase in the percentage of seeds that germinate at reduced temperatures. Plants grown from the treated seeds exhibit improved characteristics.
