the internodes ? Study from a stored cutting the callus tissue 

 which has formed. Does this differ from the callus tissue in the 

 currant and the gooseberry ? 



3. A mallet cutting is a cutting that contains a small section 

 of the parent branch forming a T, or mallet, at its base (Fig. 10). 

 Some varieties of grapes, as well as many ornamentals, root easily 

 from this kind of a cutting. It should usually have two buds. 

 Make a natural-size drawing showing the mallet. The mallet 

 portion should be about one inch in length. Label all parts. These 

 cuttings are treated in the same way as single-stem cuttings. 



4. A heel cutting' is a cutting with a small portion of the 

 wood of the previous year at its base (Fig. 10). This is similar 

 to the mallet cutting, but the heel is only a small piece shaved 

 from one side of the parent branch. 



Make a drawing showing the cutting attached to the parent 

 branch, and indicate by dotted lines where the cut should be 

 made. This cutting should contain two buds. 



Compare this with the drawing made in 3 and give the signifi- 

 cance of both forms. What advantages have mallet cuttings and 

 heel cuttings over one-eye, two-eye, and three-eye cuttings? 

 Discuss hardwood cuttings in general.
