Effects of temperature on the dual rhythmicity of the growth rate in the rice embryo were examined. At constant 20 C the periods of both rhythms of growth rate were longer than at ca. 29.3 C in a glasshouse. Although the periods were altered by temperatures, the number of cells at the onset of both rhythms was not affected. The dual rhythmicity started at the ca. 100-cell stage in the embryo at each temperature. The stability of the number of cells at the start of the rhythms indicates that the appearance of a dual rhythmicity is essential for embryonic development.
