DISCUSSION
Treatments with gibberellin can trigger flow-
ering in some plants, in others the effect can be the
opposite (Mutasa-Göttgens and Hedden 2009). In
the experiment presented here, 100% of the plants
flowered irrespective of the GA3 concentration and
the number of sprays applied. At each application,
bud development to the microscopic stage took
about four weeks. On the plants sprayed with GA3
twice, the buds developed slightly faster than on
the control plants. The application GA3 at higher
concentration resulted only in one-day prolonga-
tion of the growing period. Full flowering occurred
at the beginning of November. This time of flower-
ing coincided with All Saints Day in Poland when,
by tradition, chrysanthemums are bought in huge
numbers and ajania can become an interesting
alternative of chrysanthemum, mostly as an addi-
tive to the flower arrangements. In the experiment
reported by Dobrowolska and Janicka (2007), GA3
application at concentration of 10 mg·dm-3
did not
accelerate flowering of Impatiens hawkeri ‘Riviera
Deep Salmon’ and ‘Riviera Pink’, but it increased
the number of flowers in ‘Riviera Pink’. Schroeter-
Zakrzewska and Janowska (2007) reported that
application of GA3 increased number of buds and
flowers in Impatiens walleriana, but had not im-
pact on the time of flowering. In the research pre-
sented, concentration of GA3 did not affect the
quality of plants (length and width of the corymb,
the number of peduncles, unstained buds, buds at
the early stages of flowering, and inflorescences in
full flowering) regardless of the number of applica-
