Book excerpt: Excerpt from The Distribution of Leaves and Pear Psylla in Pear Trees Figure 1.-field placement of the measurement standards in a pear tree with an enlarged view of the guide wire for measuring the width of the sample cube. The leaves in each cube were counted using the following designations: (1) fruit spur leaf - leaves on spurs bearing a developing fruit; (2) vegetative spur leaf-leaves on any vegetative spur with three or more leaves, or fruit spurs that shed all fruit, or terminals less than 10 cm in length; (3) terminal leaf - leaves on terminals more than 10 cm in length with origins in fruit spurs or adventitious buds; and (4) miscellaneous leaf-scattered leaves, that is, one or two leaves not associated with spurs or shoots. All leaves on a spur origi nating in the sample cube were included in that cube; however, in the case of terminals and shoots, only the leaves actually originating in the cube were in cluded. In the center of the tree, where sample cubes overlapped, leaves occuring in two sample cubes were counted in one.
