Effect of low water potential of the culture medium on mesocotyl elongation of rice seedlings.
At a soil water content of water potential of ca. -3.1 to -6.2 bars, mesocotyl elongation of both indica and japonica type rice was extremely stimulated. It was also stimulated in an aseptic culture medium (2.5-4.0% mannitol, water potential ca. -3.5 to -5.5 bars). The stimulation of the mesocotyl may be caused by cell multiplication.
