one-year-old apple seedlings, and scions taken from apple trees. 

 The two parts, namely, the stock and the scion (Fig. 26), are 

 simply cut diagonally across and the two firmly tied together. 

 The cut should be one inch to one and one-half 

 inches across. This form of grafting is frequently 

 employed upon plants with soft or tender wood 

 which will not admit of splitting. 



I jj Make a drawing, natural size, and three 



inches in length, of both the stock and the scion, 

 showing the parts in position ready for tying. 

 How long did you make the diagonal cut ? Place 

 the dimensions on your drawings. To what kind 

 of stock is this method of grafting best adapted ? 

 Practice by making a 

 number of these grafts. 

 Care must be taken that 

 I HI- the cambium layers are 



in apposition. Why is 

 this important ? Dis-

 GRAFTING 



This form of grafting 

 is employed only on 

 small stocks, one or two years old. The 

 stocks are usually seedling roots, and 

 the grafting is usually performed in the 

 winter. Both the scion and the stock 

 (Fig. 27) are cut (liagonally across, as 

 in splice grafting, and the cut should be 

 at least one to one and one-half inches 

 across, according to the size of the stock. 

 A vertical cleft is then made in both 

 the stock and the scion, and the two are 

 joined by shoving the tongue of the 

 scion into the cleft of the stock. The 



two parts are held together by tying with raffia or grafting-cord. 

 If the wound stands above the ground, it must be protected by 

 applying grafting-wax over the bandage.
