178 Fruit-growing in Arid Regions 



in the peach orchard, it is probable that plum seedlings 

 were used for stocks. 



Propagation of the Apricot, Plum, and Cherry 



The apricot may be propagated on either apricot, 

 peach, or plum stocks, but the peach is most used. The 

 methods of propagation are the same as for the peach. 



Plum trees are worked on a variety of plum stocks, 

 as there is a number of different species. Special ad- 

 vantages are asserted for some of them. Peach seedlings 

 are also sometimes used. Probably the best stocks come 

 from seeds of inferior forms of the common domestica 

 plum. These usually come true to seed, and thus give 

 more uniform seedlings. Budding is the usual method 

 employed in propagating plums, although root-grafts are 

 sometimes made. 



Cherries are also commonly budded. The seeds of 

 several wild or spontaneous species are used in growing 

 stocks, the Mazzard and the Mahaleb being most in favor.
