THE PROPAGATION OF APPLE TREES. 



Effect of Budding on Root Formation. 



In order to save time in getting trees on known roots the earlier series 

 of grafts were budded usiiallj' in August after planting. Then on digging, 

 those that had formed roots from the scion were chosen for further work, 

 and those failing to do so were rejected. Six top or bud varieties and 

 fourteen stock or root varieties shown in Table 10 were used. The first 

 column of figures in the table shows the rooting from the scion of the 

 stock varieties, and these figures maj^ be used as a standard for compari- 

 son. The other columns show the rooting of the stock varieties when 

 budded with the six bud varieties. The figures in this table show great 

 variation, but, on the whole, as shown by the averages at the bottom, 

 Baldwin and Wagener tops have induced higher percentages of rooting 

 than non-budded trees, while Mcintosh, Tolman and Yellow Trans- 

 parent lowered the percentage rooting. Red Astrachan caused no change. 



It is questionable how much significance can be attached to these 

 figures. In the case of the indi^ddual lots of budded trees the numbers 

 involved are too few to place much dependence upon. In the case of the 

 averages the numbers are, of course, greater, and it is fair to assume 

 that Wagener buds, and more strikinglj^ Baldwin buds grown during the 

 second season of growth, may have, on the whole, favored root formation 

 from these stock varieties.
