and their value determined much in advance of the time when 

 they would flower on their own roots, or on plants obtained by 

 grafting or budding from the mature shoots of the seedlings. 



Hard-wooded seedlings which need to be flowered in the 

 shortest possible space of time, in order to determine their value, 

 are used for inarching as soon as the first leaves attain a fairly

stocks of the Manetti Rose. During the process of uniting the 



seedlings are kept in a moist and growing condition by 



the soil held around the union by burlap. A good 



union is effected in three to four weeks 



firm texture, as, for example in the case of the Mangosteen. 

 But when seedlings are used as stocks for the vegetative propaga- 

 tion of established varieties by uniting the stocks to small 

 branches, then larger seedlings are used, as for example, in the 

 case of the Mango.
