The Changes of phosphorous compounds in the rice kernel during germination were followed. No net change was observed in total and acid soluble phosphate. Inositol phosphate showed a markedly rapid decrease while inorganic phosphate content increased during germination. The main component of inositol phosphate was found to be inositol hexaphosphate both before and after the germination.
Free inositol content per gram of the seed before germination was 0.04mg, while after germination it reached a value of 0.55mg. Total inositol, on the other hand, decreased from 1.885mg to 1.245mg during this period. Per cent of free inositol in total inositol before germination was 2.01 and it increased to 43.99 after germination.
