Without going into details of each mode of grafting 1 

 will show you our modes of propagation of each fruit. Crabs 

 and apples are propagated by grafting. Many kinds of stocks 

 are used as follows : — 



Rin-Ki (Pirus Malus var. tormentosa) Koringo (Baccota 



var. mandshurica) Kaido (Spectabilis) Inunashi or 



Yamanashi (P. Calleryana), Kozumi (P. Toringo), 



Sand pear seedings. Quince (Cydonia Vulgaris) 



Kwarin (C. Sinensis) Boke (C. Japonica). 



Amongst them, Rinki, Koringo, Kaido, Yamanashi and 



Kozumi are commonly used as best stocks. The season of 



grafting is long, while the period from March to middle April 



is said to be the best. Usual time to cut scions is February. 



The young sTioots are cut and buried shallow in shaded and 



sheltered position for at least one week before grafting. The 



duration of storing scions may be prolonged at will. Common 



method of growing stocks is by cuttings, root cuttings, division, 



layering and by .seeds. 



Sand pears and pears are commonly propagated by grafting 

 of which Kiritsugi, splice grafting and top-working are mainly 

 performed. Cuttings and layering are seldom used. Yama- 

 nashi, Quince, Koringo and Kernpo-nashi (Hovenia dulcis), are 

 used as stocks. Among them, seedlings of Yamanashi are 

 exclusively used. Japanese pears do notstril<e well on Quinces, 

 except a few kinds. Results of double grafting of our pears 

 on quince have lately been cared for in this country. Pears are 

 wide in grafting period. They are grafted in spring from 

 March to early April. Beyond this period they can unite by 

 regrafting, which is often done in May. To cut .scions, 

 nurserymen select February. But they may be cut and stored 

 in the preceding month. Shrivelled scions unite rather better 

 than newly cut scions. Stocks are grown by seeds, cuttings 

 and layering. 



Quinces are propagated by layering, cuttings and grafting, 

 Yamanashi, Koringo, Pear seedlings and quinces are used as
