Section 4.4: Post-grafting Management of Vines: Other Grafting Techniques
Green Grafting
Green grafting is the technique where a green bud is harvested before lignification on an actively growing cane and grafted onto either a green cane or brown lignified trunk. The expression green on brown is used to describe this grafting. It can also be performed in reverse where a brown, dormant bud can be grafted onto a green cane. Both these techniques are not recommended for large scale projects as they are less certain of success. They can be used in emergency situations where dormant budwood may have failed and none is available.
Approach Grafting
Approach grafting or inarching is rarely used in vineyards. It is a technique where a rootstockis grown beside an existing vine and then grafted into the trink of the existing vine. This technique allows the rootstock to then replace the existing root system of the established vine. It maybe a good option for converting own rooted vines to rootstocks after incursions fro phylloxera or after developing issues with salinity.
