In a former chapter the importance of seeds and fruits as sources of food has been discussed. In this chapter we shall consider the relation of reproduction to three important phases of agriculture: plant propagation, plant breeding, and weed control. Propagation and breeding fur- nish better crop plants; weed control provides more pro- ductive fields. Vegetative multiplication. In the discussion of stems (page 159) attention was called to the fact that one of the advantages in imderground stems Hes in the facility with which the plant may be multipHed. From rootstocks arise new terminal and lateral buds that later form new aerial shoots, and through the death of the older parts of the under- ground stems these branches become separate plants.
