| Research Abstract |
Effects of physical or physicochemical treatment of water used for plant culture on growth and physiological functions of plants were investigated. Treatments included electrolysis and charge of electric field. These treatments might change the structure of water molecule clusters and thus affects plant physiological functions. Results obtained were the following.
1. Carrot somatic embryo culture with alkaline water obtained through electrolysis (hereafter, Al-water) inhibited the embryo growth and increased the ratio of malformed embryos.
2. Spray of electric field treated water (hereafter, E-water) on spinach leaves slightly inhibited stomatal closure, but culture with E-water did not change transpiration rate.
3. Lettuce culture with E-water did not change the growth rate.
4. E-water (with charcoal treatment), charcoal treated water, and Al-water promoted germination and growth of radish sprout, while acid water obtained through electrolysis and E-water (without charcoal treatment) inhibited them, when deionized water was used for the treatments. However, when tap water was used as original water, E-water without charcoal treatment also promoted growth. The voltage of 4,390 V for E-water resulted in remarkable growth promotion. But the repeatability of the results was low.
