For accurate evaluation of exposure effects of plants to fields such as specific life information fields and magnetic fields, a breeding method giving small standard deviations and high normal rooting rates is necessary. Standard deviations, normal rooting rates and figures of merit were examined using various breeding beds including peat moss, sponge, absorbent cotton, and nets. The breeding method using a bed of the peat moss gave small standard deviations and high normal rooting rates, enabling more accurate evaluation of the exposure effects of the plants to the fields.
