L. H. Bailey,
American Grape Training
“ All intelligent pruning of the grape rests upon the fact that the fruit is borne in a few clusters near the base of the growing shoots of the season, and which spring from wood of last year's growth. It may be said here that a growing, leafy branch [Pg 13] of the grape vine is called a shoot; a ripened shoot is called a cane; a branch or trunk two or more years old is called an arm. Fig. 1 is a shoot as it appears in the northern states in June. The whole shoot has grown within a month, from a bud. As it grew, flower clusters appeared and these are to bear the grapes. ”
