older is immaterial; the buds if still living may awake 

 from their latency and produce twigs. Very important 

 use is made of this principle in transplanting nursery 

 trees and in dehorning (Fig. 31), though it must be said 

 that in the latter practice the buds which expand are

55a. Adventitious buds. — When buds are produced at 

 unexpected points on roots, stems or leaves, they are said 

 to be adventitious, because they are not in normal posi- 

 tions. From the standpoint of the pruner they are of 

 great importance 

 for two reasons ; 

 namely, (1) they 

 may develop suck- 

 ers from the roots 

 or water sprouts 

 (Fig. 32) from 

 the trunks and 

 branches, and it 

 may be necessary 

 to destroy these ad- 

 ventitious, undesir- 

 able growths. The 

 suckers in plants 

 that have b e e n 

 grafted or btidded 

 are almost inva- 

 riably undesirable, because the stock is of a different char- 

 acter from that of the cion or top. 



In some cases the stock, being often of more vigorous 

 habit than the cion, would grow so rapidly that the cion 

 might be starved to death, as often happens with grafted 

 and budded roses that are neglected in this particular. 

 (2) Conversely, ad^•entitious buds are important because 

 they may be relied upon to produce new growths. The 

 most important applications of this development are (a)

 suckers and water sprouts always ha\e sturdy, 

 abundant and healthy roots. The trouble is in 

 the top.
