A flowering shoot from a primocane-fruiting blackberry plant.

 Image Number D4169-1

Flowering shoot from a primocane-fruiting blackberry plant growing at the ARS Appalachian Fruit Research Station. Bending and growing canes horizontally has been shown to break the inhibition of growth from lateral buds located below the primocane apex. Each of these lateral flower shoots produces as many as 12 flowers, with each developing into a ripe berry about 6 weeks later. The method and apparatus for primocane management of primocane-fruiting blackberry was patented in 2016 (patent number 9357716).
