Abstract
In order to investigate the effects of water treated with “Bakuhan-seki”, which are igneous rocks composed mainly of silica and aluminum oxide belonging to the quartz -porphyry, on the growth in plants, the ultrasonic activation of purified water in presence of “Bakuhan-seki” was examined. As the results, the mineral compositions of “Bakuhan-seki” were dissolved efficiently by ultrasonic treatment. The germination rate and seedling growth for wheat seeds increased remarkably under mineral components with a constant constrations.
