Inside the Kiwi fruit for July’s cover image

Actinidia deliciosa
Actinidia deliciosa by Mazzeo et al.

The July insert cover image shows the berry section of kiwifruit, Actinidia deliciosa; the blue spots are stained vascular bundles. In common with many other fruits, inward xylem flow decreases as the fruit matures and this can be associated with physiological disorders related to mineral content and shrivelling of fruit. Decreased xylem flow can be attributed to increased hydraulic resistance in the receptacle zone of the berry during the final period of slow fruit growth.
