Five treatments combining different
pruning practices of foliage and roots were conducted. Their
behaviour was evaluated six months after transplanting to the
field, based on seven different parameters. All were
transplanted with naked roots. A comparative evaluation was
done based on the external visual presence or absence of the
new emerging leaf or guide leaf. The results were as follows:
the plants that were not pruned, were statiscally superior to all
pruning treatments tried, not only in survival percentage
(90.33%) but also in the other six variables studied, mainly in
regard to the development of the plant measured by the total
weight recorded six months after the transplanting. The
plants with no foliage and no roots showed 63.33% of
survival and their posterior recovery, as measured by the
weight of the roots and aerial part of the plant, was markedly
inferior to all other treatments. In all cases, including the
control plots, the presence of the new emerging leaf meant a
2 to 4% increase in the survival of the plants. The seven
variables used were highly correlated: plant diameter and
height, number of leaves, root system and aerial part weight,
total plant weight, and survival percentage.
