ASEXUAL PROPAGATION ON ROOTS OF OTHER PLANTS 85 



EXERCISE IV. Observation of budding and grafting methods, and 

 of grafted and budded trees. 



1. If there is a nursery in your section, visit it to see how grafting 

 and budding are done. 



2. Examine some grafted trees in your neighborhood. Notice the 

 point at which the grafting or budding was done. Did a good or poor 

 union result? Do the stock and cion appear to be growing at the same 

 rate? In what varieties of grafted trees do you notice the cion to be 

 larger than the stock or the reverse? How do you account for the 

 difference in growth of the stock and cion? (See Fig. 61.)
