GRAPE-PRUNING ON THE PACIFIC SLOPE 181 



The most iini)ortant characteristic of the variety in making 

 a choice of a pruning system is whether it normally or usually 

 requires short, half-long, or long pruning. With this idea, the 

 principal grapes grown in California, together with all those 

 grown at the Experiment Station on which data exist, have 

 been divided into five groups in the following list :
