Grape Grafting.

shade them for a few days. The grafts soon callus at the lower 

 ends and emit roots of their own. 



Although the above graft appears to be very successful, the work 

 and care required for its execution will probably prevent its gen- 

 real use. It might properly be 

 called an inserted side graft, and 

 it is probable that if the grafts are 

 made early enough in the winter, 

 union would take place before active 

 growth begins, and less care benec- 

 essarv to insure success. 



SUMMARY. 



Q

1. The living or growing cells 

 in the stem of the grape are largely 

 in the cambium layer. Page 460. 



2. A union between cion and 

 stock will not take place unless the 

 cambium layers are in close contact. 

 Page 461. 



3. The grape is not difiScult to 

 graft, but the operations must be 

 carefully performed. Page 461. 



4. The cion should be dormant 

 or practically so at the time of in- 

 sertion. Page 462. 



5. The stock may be dormant, 

 or the sap may be active, but the heavy flow of sap which occurs 

 in spring should be avoided. Page 462. 



6. Grapes may be grafted in the fall, early spring, or late 

 spring. Page 462. 



7. When the work is done in the fall or winter, protection 

 must be given in this latitude. Page 463. 



8. Early spring is on the whole the best time for grafting 

 grapes, and the earlier it is done the better. Page 463. 



9. Cions inserted late in the spring will unite with the stock 

 provided they have been kept dormant. Page 464.
