This study investigated the effect of various types of water on the culture of embryos excised from rice seed. The rate of embryonic growth was highest in rainwater, showing a value of 64% 3 weeks after transplanting. Elongation of the auricle over 4 months was remarkable under rainwater conditions. Average leaf formation rates in purified water, rainwater and filtration rainwater were 4, 4 and 8, respectively. These findings suggest that slightly treated water affects rice plant embryo growth.
