Rice plants in water cultures were subjected to N, P or K deficiency at the time of initiation of the panicle primordia and reduction division of the pollen-sac mother cell. N or P deficiency decreased protein synthesis and respiration rate in the roots. N deficiency appeared to promote the utilization of sugar and organic acid, and P deficiency the utilization of fat or N compounds. K deficiency increased the respiration rate of roots.
