EXERCISE XIV 



A STUDY OF ROOT CUTTINGS 



Material. Blackberry and horse-radish roots and planted cut- 

 tings of each. 



Many plants can be multiplied with ease by means of short 

 cuttings of the roots. True root cuttings possess no buds at all, 



FIG. 8. Root cuttings of the horse-radish 



but buds develop after the cutting is planted. The roots are cut 

 into pieces from one inch to three inches in length and planted 

 horizontally. 



1. Secure roots of the blackberry and horse-radish, both of 

 which are easily propagated by root cuttings. Practice making 

 a number of these cuttings. Make a natural-size drawing of a 

 root cutting from each of the plants. Look carefully for buds. 

 Can any be found ? Now secure cuttings of the above that have 

 been planted for some little time. Examine these for buds. 

 Where are the buds found ? Make a drawing showing the bud, 

 and differentiate between the two cuttings. Discuss.
