PLANT PROPAGATION 



other, according to whether stock ripens earlier or later than 

 cion. It follows, of course, that keeping quality is affected in the 

 same degree as maturity. From what is known on this subject we 

 are warranted in saying that earliness is promoted only when the 

 stock ripens its wood earlier than the cion ; lateness, when the stock 

 wood ripens later. 



7. Color of fruit may be changed by stock. There is little evi- 

 dence to substantiate the claim that the characteristic color of a 

 fruit is changed by the stock, but, as all know, color is heightened 

 by earliness and lessened by lateness in the maturity of a variety. 

 In cases, then, in which stock influences time of maturity, color 

 may be more or less changed. I know of a Mclntosh orchard the 

 fruit of which is much brighter in color and matures nearly two 

 weeks earlier than Mclntosh on standard stocks, apparently because 

 grafted upon Oldenburg stocks. 



8. Size of fruit is often increased by stock. I cite only pear on 

 quince as an example. Many others might be adduced. 



9. Stock affects eating qualities of fruit on cion. Larger, crisper,

 pits of cultivated varieties secured from canneries.
