364 SEEDING AND PLANTING 



II. Vegetative plants: Plants grown from vegetative parts 

 of the mother tree. 



1. Rooted cuttings: Sections of branches that have 



been rooted by planting for a time in cultivated 

 soil. 



2. Layers: Twigs that have become rooted while still at- 



tached to the mother tree but later detached. 



3. Suckers: Shoots that arise from adventitious buds on 



the surface roots of the mother tree and are later 

 detached. 



B. Incomplete planting material: Plants with either root or 

 shoot but not both. 



1. Unrooted shoot cuttings: Parts of the branches of the 



mother tree of various sizes and ages. 



a. Sections of branches cut from rapidly developed 1- and 



2-year wood. 



b. Larger sections cut from old wood. 



2. Root cuttings: Parts of the roots of the mother tree of 



various sizes and ages. 



All species may be grown from seed. Plants grown from seed 

 are usually more thrifty, live to greater age, and on the whole are 

 more desirable than other classes. Incomplete planting material 

 usually is set in the nursery for a year before placing in the per- 

 manent plantation. 



4. The Size and Age of the Planting Material 

 An adequate description of planting material should give both 

 the size and age of the' stock. It is customary to give the height 

 in inches or feet and the number of years that it has grown both 

 as a seedling and as a transplant. Thus, 10-inch white pine 

 (2-2) is planting stock 10 inches high that has been grown in the 

 seedbed 2 years, in the transplant bed an additional 2 years, 

 and has been transplanted once; 5-inch yellow pine (1-1) is 

 planting stock 5 inches high that has grown one year in the seed- 

 bed and an additional year in the transplant bed; 18-inch Scotch 

 pine (2-1-1) is planting stock 1 foot 6 inches high that has grown 

 2 years in the seedbed and 2 years in the transplant bed, but 

 has been twice transplanted. 



The stock used in planting varies in height from a few inches 

 to several feet. Because of the expense involved, stock more
