The separated and combined effects of pruning and girdling branches on flower initiation and flower development were investigated in ‘Yu Her Pau’ litchi (Litchi chinensis Sonn.). Light pruning and girdling did not influence the flowering, but flowering in heavy pruning was very little in the absence of girdling. Light pruning did not delay the date of panicle emergence, but heavy pruning delayed 15 days. Girdling pre se did not influence the date of panicle emergence. Pruning and girdling did influence the panicle development. Pruning reduced panicle length and the response was stronger in heavy pruning. Combined treatments of pruning and girdling reduced panicle length more than spearated treatment. Heavy pruning increased the proportion of female flowers, but not in light pruning. The proportion of female flowers increased by girdling but the response had no relations to pruning. The results of this experiment indicated that the effects of pruning on flower initiation and flower development are related to environmental factors, especially air temperature, during flower induction and early stage of flower development. However, the effects of girdling on flower initiation and flower development depend relatively on the changes of physiological mechanism in plant. The effects of pruning and girdling on fruit set were discussed in this report.
