Research Abstract

o break the limitation of grain growth in the rice panicle solution culture that grain growth stops within one week, an increase in a solution absorption surface area in lower stem positions and an enhancement in absorption of lower concentrate cultural solution under lower humidity were tried. As the result grain growth term was able to extend by one week more.
