Starch accumulation and lignin formation with relation to several enzyme activities n hulls were studied with fertile and sterile grains during ripening. 1. Starch accumulation could not be observed in the hulls of sterile grains during ripening. However, in the hulls of fertile grains, that was observed at early and middle stage of ripening, although it disappeared thereafter. 2. Lignin formation could not be almost observed in the hulls of sterile grains during ripening, whereas it proceeded in the hulls of fertile grains with ripening. 3. In the hulls of fertile grains, the activity of amylase was lower and that of phospholylase was higher than in those of sterile grains during ripening period.4. Peroxydase activity was much higher in the hulls of fertile than in those of sterile grains. From these results, hulls might play several roles not only as a pool of mineral elements and carbohydrates as shown previously but also as the protector of kernels. The physical strength or hulls may increase through several biochemical progress which triggered by the fertilization as shown in this report.
