THE EFFECT OF CINCTURING ON FLOWERING OF LYCHEE IN SUBTROPICAL QUEENSLAND |

| Abstract:
The effect of cincturing on growth and flowering of 3 lychee cultivars (Bengal, Brewster and Tai So) was investigated at a range of environmentally different sites in subtropical southern Queensland, Australia. Cultivars at these sites displayed a range in the level of natural vegetative dormancy in winter and flowering in spring. There was an inverse correlation between the flowering response to cincturing and the potential flowering of the control trees. Cincturing reduced flowering in trees which would have flowered profusely in spring. This occurred when the cincture recovered prematurely to allow vegetative flushing in winter. These results suggest that some loss of yield may occur in years and cultivars with good flowering. | |
