of September. In each combination, the inflores-
cence buds development to the microscopic stage
took about four weeks. Buds were visible by naked
eyes 7 to 10 days later. Irrespective of the concen-
tration, the buds on the plants sprayed with GA3
twice developed slightly faster than in the control
plants. Full flowering occurred at the beginning of
November (Tables 1 & 2).
The application of GA3 at higher concentra-
tion resulted only in one-day prolongation of the
cultivation period, whereas, irrespective of the
concentration, the double spraying with GA3 short-
ened the growing period by two days, which was
not observed in those sprayed once or three times
(Table 2).
It was observed that both the concentration of
GA3 and the number of its applications affected the
length of main shoot. GA3 at higher concentration
elongated them by only 3 cm. However, irrespec-
tive of the concentration, the plants sprayed twice
were longer (an average of 3 and 5 cm) than those
sprayed once or than the control. Neither the con-
centration nor the number of GA3 applications
affected the width of the plants, which reached on
average of 15.5 cm. No significant differences in
the interaction of both factors on the length of
main shoots and the width of the plants were noted
(Table 3).
Regardless of the number of GA3 application,
the concentration did not affect the quality of inflo-
rescences in the corymbs. The number of GA3
sprays, affected all those features, except for the
number of peduncles and unstained buds. The
corymbs produced by the control plants were
longer than those sprayed two times with GA3. The
plants treated with GA3 produced narrower
corymbs but there were no significant differences
in the width of the corymbs between single, double
and triple GA3 application. Both at 250 mg·dm-3
and at
500 mg·dm-3
GA3 concentration the plants
produced similar number of unstained buds, buds
