Hydraulic conductance and photosynthesis were measured in kiwifruit (Actinidia sp.) There is some thought that trunk girdling may be having an elicitor effect on kiwifruit plants, helping switch on their bacterial defence response and reducing their susceptibility to Psa. Trunk girdling involves removing a narrow strip (usually 3-7mm) of the outer layers of the trunk (bark + phloem) so that the phloem layer is completely separated.
