All these facts favor the view of a slower transformation of 

 saccharose into higher compounds, although saccharose does not play 

 the same role in the development of all other plants, as found in 

 T. Kettt's experiments with the grains of oat-plants, (v. South Carolina 

 Agr. Expt. Stat. Bull. No. 165). 



It is observed in Tables 21 and 22, entitled "Glucose" and 

 "Saccharose," that the leaves colled between 10 : oo and 11 :oo A. 

 M. contain a greater amount of glucose than saccharose. This is 

 probably due to a more active formation of glucose, than to migration 

 from the leaves. The percentages of these sugars contained in the 

 leaves in the morning and in the evening, are cited again from Table 

 18, for ready reference, to show the active production of glucose. 



Table 28. Percentage of Sugars in Leaves. 



In the morning the leaves contain a much lower percentage 

 of glucose than of saccharose. By evening the glucose and the 

 saccharose have increased by 2.72 % and 1.61 % respectively. The 

 migration and transformation of these sugars must exert a very 

 considerable influence on their accumulation in the leaves. It may 

 be bclieaved that the more active transformation of glucose than of 

 saccharose in the stems and grain, as described above, is also true
