The effect of V-trellising on primocane-fruiting raspberries (Rubus idaeus L.)

Abstract

Primocane-fruiting (PF) red raspberries (Rubus idaeus L. cvs. Summit and Heritage) at two locations in Southern Ontario were maintained in a hedgerow or trained to a V-trellis to determine the effect of trellising on productivity. Trellising increased yield per cane in 'Heritage' at Cambridge by 56% with a concomitant increase in fruit number per cane, but did not significantly affect yield of either 'Heritage' or 'Summit' at Campbellville. Plots at Campbellville had significantly greater cane densities than plots at Cambridge, and so light penetration into the walls of the V-trellis at Campbellville was likely diminished due to crowding and competition between canes. Response of PF raspberries to V-trellising may be dependent on cane density of the planting. © 2005 by The Haworth Press, Inc. All rights reserved.
