ASEXUAL PROPAGATION ON ROOTS OF OTHER PLANTS 71 



budded with a given amount of cion wood than can be 

 grafted. These are important considerations when many 

 trees are propagated. 



106. Types of budding. Named according to the man- 

 ner in which the budding is performed, the kinds are: 

 shield-budding; twig- or spur-budding; flute-, patch-, or 

 veneer-budding; plate-budding; and ring- or annular- 

 budding. Shield-budding is by far the most common, the 

 other methods being used only in cases where shield-budding 

 does not give satisfaction. 



107. Shield-budding. The main steps in shield-budding, 

 as in other methods, are : 



1. Preparing the stock. 



2. Selecting, preparing, and keeping the bud-stick. 



3. Cutting the stock for the bud. 



4. Removing the bud from the bud-stick and inserting 

 it in the proper place in the stock. 



5. Tying the bud. . 



After-treatment necessary to the production of a tree 

 includes the following : 



a. Cutting the ligatures to prevent girdling. 



b. Cutting back the top of the budded tree at the proper 

 time to force the bud into growth. 



108. Preparing the stock previous to budding. The bark 

 of the stock should peel readily. If the bark is tight and 

 does not peel, it is advisable, if possible, to irrigate the rows 

 a few days previous to budding. All leaf growth and suckers 

 below the point where the bud is to be placed upon the stock 

 should be rubbed off, but this should be done not longer 

 than three days before budding the trees; otherwise the 

 bark is likely to tighten. 



109. Selecting bud-wood. Except in dormant budding 

 to be explained later, bud-wood should be well-hardened 

 wood of the current season's growth. It should be taken 

 from bearing trees in order that there may be no mistake as
