Propagation of the Pecan 33 



men and growers in regard to the best source of nnts for the 

 production of pecan nursery stock. Nurserymen in northern 

 Florida and in southern Georgia, where the greater propor- 

 tion of all pecan nursery trees are grown, are generally of 

 the opinion that nuts from Louisiana and Texas do not germi- 

 nate as well as the eastern pecans. The statement is also 

 made that southern seedlings are not satisfactory for northern 

 cions, and vice versa. Neither makes satisfactory progress 

 when the two extremes are used in grafting, owing to the 

 difference of time in starting growth in the spring, and in 

 maturing wood or becoming dormant in the fall. The use 

 of stocks from the northern border of the pecan-growing 

 area, however, offers a field for further investigations to the 

 experimenter who may be in search of stock that will some- 

 w^hat dwarf and increase the productiveness of southern 

 varieties. 



Nurserymen who contemplate propagating pecans to be 

 grown toward the northern limits of their culture should 

 secure nuts for growing stock as far north as the trees are to 

 be planted in order to give them sufficient hardiness to with- 

 stand the climatic conditions. However, the nurseryman 

 propagating trees for the great mass of pecan-growers of 

 the lower South, where practically all the large commercial 

 orchards are situated, may expect good results by using plump 

 nuts, medium in size, selected from vigorous growing healthy 

 seedling trees in the same locality or in a latitude and climate 

 approximating that of the nursery. When nurserymen have 

 access to the same seedling pecan trees year after year, they 

 find that nuts from certain individuals produce much better 

 stock than from others, even though there may be no apparent 

 difference between the two lots of nuts.
