The early elongation of the current shoot in the year after treatment was less if the treatment was performed. A branch completely girdled will fail and when the main trunk of a tree is girdled, the entire tree will die, if it cannot regrow from above to bridge the wound. With trunk girdling, maturity is advanced and therefore orchards should be harvested according to Brix rather than any other consideration. Little is understood regarding the physiological effects of these practices in kiwifruit. There are some insect pests who girdle tiny twigs or flower parts. chinensis) to trunk girdling and root pruning. var. Patterson, W.P.
