The slioot pubescence is one of the more important characters. Shoots may lack pubescence as in Lombard, have a medium amount as in Field, or be heavily pubescent as in Monarch (Figure 2). Hedrick (3) and Shoemaker (7) have published data on pubescence that are somewhat at variance with the data given in this bulletin. In particular, some of the European varieties that they have described as having pubescent shoots are described herein as essentially glabrous. However, both Hedrick and Shoemaker studied shoots from bearing trees and it is apparent that pubescence on such shoots is not always the same as that on shoots of nursery trees. The color of the growing tips is a valuable character for recognition. To be most valuable, observation should be made while shoots are making active length growth, as in the early part of the growing season. The small young unfolding leaves at the shoot tips vary in color from the yellowish green of.
