Plant vigor can additionally be modified by rootstock selection as can yield and quality.

When using the saddle graft the rootstock and scion should be as equal in size (diameter) as possible. The number of grafts completed per day was limited by the complexity of the graft and the skill needed.

About 20 years ago, grape propagators in Okayama switched to an automatic-type grafting machine (that was manufactured in Germany). Techniques for grafting using this new automated machine were developed and these are used today. After changing to the automated grafting machine, the number of grafting per day and success rate rose
