The effects of foliar application of phosphate was investigated in the light of plant physiological point of view. The phosphate applied on the foliar both in meiosis and heading time was penetrated considerably into the rice. The amount of P absorbed by foliar application at high temperature was higher than that at low temperature but still considerable amount of P was absorbed at low temperature. The phosphate applied on younger flag leaf was absorbed more vigorously than the second and third leaves. The absorbed P on leaf was translocated to the panicle, especially on the brown rice starch, then moved to another panicle wherever the phosphate was needed. The major fraction of absorbed P under high temperature condition was T.C.A. soluble-Ba insoluble phosphate of mainly phytic form but Ba soluble-EtOH insoluble fraction, sugar phosphate ester, was identified as dominant P under low temperature condition.
