ASEXUAL PROPAGATION ON ROOTS OF OTHER PLANTS 81 



by many to the cleft for stocks having a pith in the 

 center. 



131. Bark-graft. When the bark will peel, large stocks 

 are frequently grafted by this method. The stock is cut off 

 and vertical slits are made in the bark 



where the cions are to be inserted. The 

 cions are cut as in Fig. 58 and the tongues 

 inserted under the bark. The top of the 

 stock is then wrapped tightly with string 

 and waxed over. 



132. Veneer-grafting is used almost en- 

 tirely in the greenhouse. A shallow notch 

 is cut in the stock, and the cion is fitted 

 in the notch. The cion is tied in with 

 raffia and the grafted plant is kept in the 

 greenhouse where there is plenty of mois- 

 ture in the atmosphere. 



133. Side-grafting. In this graft a 

 cut is made in the side of the stock, 



and the cion, trimmed so 

 that its base is wedge- 

 shaped, is inserted in the 

 cut. Out-of-doors the 

 wounds must be waxed. 

 Side-grafting is much used 

 with stone-fruits like the 

 peach (Fig. 59). 



134. Saddle-grafting. In 

 grafting many greenhouse 

 plants, the stock is cut in the 

 shape of a wedge, and the cion 

 is split or notched, and placed 



ver ^ ne Wedge.

proach-grafting. In a few special cases, marching is useful.
