Abstract

MENDONCA, Vander; RAMOS, José Darlan; ARAUJO NETO, Sebastião Elviro de  and  RUFINI, José Carlos Moraes. Production of 'ponkan' tangerine tree after pruning recovery. Ciênc. agrotec. [online]. 2008, vol.32, n.1, pp. 103-109. ISSN 1413-7054.  http://dx.doi.org/10.1590/S1413-70542008000100015.

This research aimed to test top pruning effect on the lowering of plant canopy, pruning the lower canopy on the recover of 12 years old 'Ponkan' tangerine tree, 4 meters height, 6 x 4 spaced and grafted on 'Cravo' lemon rootstock. This experiment was carried out at Vito Crincoli's Farm in Perdões, MG. It was carried out under randomized plots in a factorial scheme of 4x2, top pruning (without pruning, pruning at 3.0; 2.5 and 2.0 m) and skirt pruning (with and without pruning) with 4 replications. Plot size was composed by three plants. Heavy pruning of the top canopy lowered the first tree yield, however, and in the begining of the second year, the plants showed a very good recover. The same behavior was seem for the third harvest when several kinds of top pruning did not differ in the yield. Skirt pruning treatment was superior to that without any pruning.
