Abstract The structure of stigma - style tissues in kiwifruit (Actinidia chinensis Planch. cv. 'Hayward') flowers was examined before, and after, hand-pollination and the course of pollen tube development was followed. At the time of flower opening the style had a well defined canal which opened at its distal end to form a V-shaped stigmatic furrow. The surface of the furrow was covered with unicellular papillae. The exposed wall of each papilla was covered with a cuticle and a distinct pellicle. The papillae were supported by a layer of hypodermal cells and an extensive layer of thin-walled transmitting cells. The transmitting tissue extended from the tip of the style through the stylar canal to its junction with the ovary. A single vascular strand, which extended along the length of the style adjacent to the stylar canal, branched into the stylar parenchyma on each side of the V-shaped furrow.
