| Abstract:
Kiwifruit stems have a normal cambial structure. Phloem has long-lived sieve elements with scalariformly compound sieve plates like those in Vitis. Radial continuity is disrupted by crushing and sclerification of phloem tissues. Kiwifruit wood is diverse in structure. Fibre-tracheids are common. The wood is semi ringporous; perforation plates may be simple, scalariform, reticulate or combinations of these. Latex paint infusion of 1–2 m lengths of 10-yr-old kiwifruit stems shows that vessels are up to 0.8 m long. Vessel elements are ca. 0.1 mm long. Longest and widest vessels occur in early wood of outer growth rings. Average vessel-length is 14–16 cm. | |
