The research was conducted from June 17 to
November 2, 2010, using Ajania pacifica /Nakai/
Bremer et Humphries ‘Bea’ cultivar. The 7-8 cm
long cuttings from parent plant were rooted in peat
substrate Florabalt Plus Semi 1 (pH 6.0), in plastic
pallets with 3 cm in diameter openings on June 17.
The rooted plants were divided into four groups: 1
(control combination) - the plants sprayed with
distilled water, while plants in groups 2, 3 and 4
were sprayed with solution of gibberellic acid
(GA3) one time, two times or three times respec-
tively. Each group was divided into two subgroups:
the first one was treated with GA3 at concentration
of 250 mg·dm-3
and the second one with GA3 at
concentration of 500 mg·dm-3
. The first spray was
done on July 15 (the fifth week of growth), then
successively in the sixth and seventh week. On
July 29, after six weeks of growth, the plants were
replanted onto tables 25 cm deep, filled with peat
substrate Florabalt Plus PV 1, pH 6.0, at the den-
sity of 100 plants·m-2
. Starting from August 15, the
plants were grown under natural short day (lessthan 16 hours), which initiated the generative
phase. During the phase of vegetative growth the
temperature was 25.8/24.3 °C and during the gen-
erative phase 20.2/19.5 °C, respectively.
The experiment was set up in randomized
block design. Each experimental combination con-
sisted of 16 plants; 4 replication x 4 plants. The
following dates were recorded: the appearance of
the inflorescence bud, when it was well visible
with the naked eye, beginning of flowering when
in a half of the buds the first coloured flowers were
visible and full flowering when a half of the inflo-
rescences were in full bloom. For presentation in
the tables, weighted means were calculated from
these dates. The number of days from the begin-
ning of short days until the appearance of the inflo-
rescence buds at microscopic stage of development
and the number of days starting from bud emer-
gence to the beginning of flowering (macroscopic
stage development), as well as the period of culti-
vation (from the start of short days to the begin-
ning of flowering) were calculated. The length of
main shoot, measured from the ground to top-
reaching inflorescence; width of the plant, which
was the mean of the measurements of two widest
dimensions of the plant; the length of the corymb,
