4. Most of the hydrolysed starch is either utilized in 

 metabolic processes or transferred to the adjacent parts of the 

 stem, as is evidenced by the change in the total carbohydrate 

 content of fruit spurs. This occurs during the dormant period 

 when metabolic processes are at a minimum. There is also a 

 possibility that some of the carbohydrates are used in fat 

 synthesis or other syntheses at this time, but no data were 

 obtained on this point.

Fig. 3. A curve showing the average minimum temperature of the campus 

 (Ohio State University) from May to April, 1919-1920. The ordinate represents 

 the temperature in F° and the abscissa, the season of the year. 



5. In the early spring, especially in March and April, 

 during the swelling of buds and the early growth of leaves and 

 flowers, the starch and sugars disappear very rapidly, apparently 

 being utilised in the formation of new growth and the respiration 

 of the growing cells. 



6. The total sugar, especially reducing sugars, increases in 

 December and is at its maximum during December, January 

 and February. This increase of total sugar does not account 

 quantitatively for the decrease of starch during the dormant 

 period.
