nearly related to the plant which is to be propagated as pos- 

 sible ; e. g. , Parkman's pyrus does better on P. floribunda 

 than on the common apple stock. 



Quamoclit. See Ipomoea. 



Quassia. Simarubece.

Quercus (Oak). Cufuliferce. 



Stocks are grown readily from seeds, which may be sown in 

 the fall without stratification. The evergreen species are 

 sometimes grown from cuttings. Varieties are grafted on 

 stocks grown from wild acorns. The stocks are potted in 



. the fall and the grafting is performed in January and Febru- 

 ary, or sometimes in August. 



Quince (Pyrus Cydonia, P. Japonica, P. Cathayensis], Rosacece. 

 All quinces can be grown from seeds, the same as apples 

 and pears ; but seeds are not common in the market, and 

 are therefore little used in this country. The fruit-bearing 

 quinces are propagated most cheaply by means of cuttings 

 of mature wood. The cuttings are taken in the fall, and are 

 stored in sand, moss or sawdust until spring, when they are 

 planted out-doors. Long cuttings 10 to 12 inches are usu- 

 ally most successful, as they reach into uniformly moist earth. 

 Cuttings are usually made of the recent wood, and prefera- 

 bly with a heel, but wood two or three years old will usually 

 grow. With some varieties and upon some soils, there is 

 considerable uncertainty, and layerageis therefore often em- 

 ployed. Mound-layering (see page 35) is practiced where 

 extra strong plants are required. Long root-cuttings, treated 

 like those of the blackberry and raspberry, will also grow. 

 Many nurserymen bud or root-graft the better varieties 

 upon stocks of Angers or other strong sorts. These 

 stocks are imported or grown from seeds or cuttings. The 

 Chinese quince succeeds upon the common quince. In order 

 to secure extra strong plants and a uniform stand, some 

 growers graft quince cuttings upon pieces of apple or pear 

 roots. In such cases the plants should be taken up in the 



; fall, when the quince will be found to have sent out roots of 

 its own; the apple root should be removed, and the quince 



: replanted the following spring in the nursery row, otherwise 

 suckers frequently spring from the stock and interfere with 

 the growth of the quince. The union is sufficient to nurse 



' the cion for two or three years. 



The flowering or Japanese quince is best propagated by
