Pruning is a series of cut branches/twigs plants in
the framework to the canopy formation (cut forms), plants
rejuvenation (pruning rejuvenation), or plant maintenance
(pruning maintenance). By cutting, the plant canopy will
form a pattern of 1-3-9-27, which is 1 main stem, 3
primary branches, 9 firstly tertiary branches and 27
secondary tertiary branches. According to Purnomo et al.
(1996) formation of mango crop canopy is significantly
determine the production, including to the fruit quality.
But in general, farmers do not apply the canopy pruning to
mango so that the canopy formation is less regular and low
productivity. According to Ginting et al. (2008) early
pruning to canopy formation is intended to spur the growth
of vegetative shoots are dormant so that shoots grow a lot
and easy to set up a canopy. Davenport (2006) said that
three pruning strategies have been developed to prevent
the trees from getting large through annual pruning as part
of a flowering management program, reshape intermediate
sized trees to be smaller, more manageable sizes and
completely rejuvenate large trees that are no longer
productive due to their size and height.
In addition to fertilizing, pruning can also
stimulate the flower formation. Pruning can increase the
leaf buds formation by 78% and the flower buds number
of 31% (Hidayat, 2005).
The purpose of this study was to compare the
growth speed of mango shoots after pruning on grafting
seedling and rootstock.
