TERMINOLOGY OF THE VINE 497 



base of each cane is a basal bud or eye (B). In 

 counting the number of eyes on a spur, the basal 

 eye is not included. A cane cut at K 1 , for in- 

 stance, leaves a spur of one eye, at K 2 a spur of 

 two eyes, and so on. When more than four eyes 

 are left, the piece is generally called a fruiting 

 cane (Fig. 314, /). The canes (c^c 1 ) coming from

two -year -old wood (w 2 ) possess fruit buds ; that 

 is, they are capable of producing fruit -bearing 

 shoots. Watersprouts (ws) and suckers (s) do 

 not ordinarily produce fruit -bearing shoots. Be- 

 low the basal bud each cane has one or more dor- 

 mant buds (b, Fig. 316), which do not grow unless 

 the number of eyes left by pruning or frost is 

 insufficient to relieve the excess of sap pressure. 

 These buds produce sterile shoots. Each eye on 

 a cane has at its base two dormant buds. One 

 of these sometimes grows out the year it is
