5. Immature twigs can be caused to absorb cane sugar and store it 

 in such form as to be available as a food supply for increased root 

 development. 



6. Mature twigs are but slightly benefited, or may even be somewhat 

 injured, by treatment with cane sugar. 



7. As a result of placing the base of a cutting in a sugar solution for 

 a short time, the terminal bud of the twig fails to develop in a normal 

 manner and the lower buds form shoots instead.. 



8. Any injury accompanying treatment with sugar is due, not directly 

 to the sugar, but to the resulting products formed by bacterial or fungous 

 action.
