1. This experiment was made to clear the effect of light upn the development of tillering primordium and tillering bud in rice seedling. 2. The degrees of light used were four as follous, A plot-non-shading, degrees of light 100. B plot-shading about 80. C plot-Shading about 65. D plot-shading abont 35. 3. In the develupments of the separate tillering primordium and tillering bud, the tendencies of increasing and decreasing in proportion to the degrees of light were observed. 4. In the second tillering primordium and tillering bud, at A and B plots they were observed to tiller but at C and plots tillering was not observed and their developments was remarkably restrained. 5. In the third tillering primordium and tillering bud, at A, B and C plots they were observed to tiller but at c plot their developments was restrained to some degrees. 6. In the fourth and fifth tillering primordinm and tillering bud, at A, B and C plots it is guessad that they will be tillered. 7.
