PLATE 105 
Further evidence that crowngall inoculation stimulates bud development. Pairs of 
leaves from two plants inoculated June 23, 1920, and photographed August 31. Nearly 
every inoculated leaf notch has given rise to a shoot. No shoots from the lower (un- 
inoculated) leaves or from uninoculated notches on the upper leaves. From B at X 
proliferated notches were cut away at the end of July for some of the photographs of 
that date (PI 106). These inoculations were made by single needle thrusts directly 
into the region of the bud. A, natural size; B, about one-third natural size.
