Growth curves of fruits and shoots in relation to time after
full bloom of “Anna” apple trees growth at 2470 m altitude
were determined in Paipa (Colombia). The evaluated
parameters in fruits every four days were: fresh weight,
dry weight, length /diameter ratio of fruits. Shoot growth
was meassured at the same periodicity that by fruits. The
regression ecuations for evaluated parameters are reported
in this paper. The fresh weight increase of fruits was
slow until 46 days after full bloom (dafb), then it was
quickly until 62 dafb; among 62 and 74 dafb appeared a
slow growth phase again; and finally, the growth intensity
increased until the ripening time. The dry weight increase
of fruits was slow until 58 dafb; and then it was quickly
until 94 dafb und finally decresased from 94 dafb. The
length /diameter ratio decreased until 90 dafb and then it
stabilished. Shoots grew quickly until 70 dafb, and then
their growth intensity decreased among 70 and 94 dafb;
and finally, their growth delayed from 94 dafb. With this
information it is possible to make a more rationale plan for
some culture activities at this apple variety cultured in the
Colombian highlands, that present similar agroecological
conditions to those in which this study was done.
