rose in the plant organs, where the soluble sugars change very actively 

 into insoluble nutrients, suggests that in the plant body of rice the 

 transformation of saccharose into higher compounds does not proceed 

 so rapidly as does that of glucose. In a similar way, a great deal 

 of saccharose may be stored in the stems of sugar cane and in the 

 roots of sugar beet. 



In maize just after flowering, the percentage of reducing sugar 

 exceeds that of saccharose ; yet the latter sugar is found to have a 

 greater percentage towards maturity. The percentages of these sugars 

 during the maturation of maize are as follows ;

It is noticed in T. E. Kcitt's work entitled " Sweet Potato In- 

 vestigation," (South Carolina Agr. Expt. Stat. Bull. No. 16529 

 1912), that when this crop approaches maturity, there is a similar 

 relation between the amounts of glucose and of saccharose, as ob- 

 served in the case of ripening maize. Some results of his analysis 

 are given in the following table :
