Abstract

Claims (5)

1. A seed germination promoting liquid comprising water containing reactive oxygen species and a nanoparticle catalyst in a stationary state, the seed germination promoting liquid being produced by causing cavitation in water and generating plasma therein using a plasma generation mechanism in which a pulse voltage is applied across electrodes in the water including air bubbles mainly containing water vapor generated by the cavitation.

2. The seed germination promoting liquid of claim 1 , wherein the nanoparticles are made of a component of the electrode.

3. A seed germination promoting method comprising: lubricating a seed using water containing reactive oxygen species and a nanoparticle catalyst in a stationary state, the water having been produced by causing cavitation in water and generating plasma therein using a plasma generation mechanism in which a pulse voltage is applied across electrodes in the water including air bubbles mainly containing water vapor generated by the cavitation.

4. The seed germination promoting method according to claim 3 , wherein the water containing the reactive oxygen species and the nanoparticle catalyst in the stationary state is used in an environment where the water is not in contact with organic matter, excluding the seed.

5. The seed germination promoting method according to claim 3 , wherein the nanoparticles are made of a component of the electrode.
