Flowering and fruiting of lychee trees in response to girdling of branches

The effects of girdling of branches on flowering and fruiting of 17 years old 'Bengal' lychee trees were evaluated. The treatments consisted of girdling of main branches, and branches with 6, 4 and 2 cm of diameter and the control. The experiment was conducted in a randomized block design, with 5 replicates. The evaluations in relation to flowering were: flowering per tree and per quadrant and length of flower panicles; in relation to fruiting were: fruit set per panicle, fruit weight, longitudinal and equatorial diameters, soluble solids, harvest time and production. The girdling in the main branches induced larger flowering, without influence on the flower panicles characteristics, there were no differences in the fruit set, but with an increasing in the flowering, it increased the production, with significant anticipation of the harvest.
