KINDS OF MULTIPLICATION

as it gets a good start the next summer, it will begin to 

 send out some branches from near the point where the 

 leaves and roots come together. These will run along 

 the ground instead of growing straight up. At a distance 

 of several inches from the plant, this runner will put out 

 small roots from its lower side, and leaves will grow from 

 the upper side. These soon take the form of a small 

 strawberry plant connected with the original one. Several 

 of these young plants may start up in a similar way 

 around the parent. For a considerable time these young 

 plants remain connected with the old plant by the runners, 

 but the runners may gradually die as the new plants get 

 roots and leaves enough to support full growth. In time 

 these daughter plants repeat the process. 



An exactly similar thing takes place in one of the molds 

 that we often find on our cultures of bread and similar 

 substances. The 

 spores are borne on 

 branches that grow 

 up into the air, 

 but other branches 

 grow along the 

 surface of the 

 bread, and at the 

 end send root-like 

 processes down 

 into the bread and 

 s p o r e-b earing 

 branches up into the air 

 produced. 



The runners just described occur at the surface of the 

 soil or the substance over which it is growing. In many 

 plants, such as some of the grasses and canes, the runner 

 passes along beneath the soil, and here and there sends 

 up a new stalk. These may branch underground and 

 thus produce a great number of new plants from one.
