Primula veris seeds collected from natural populations were tested
for their germinability. They exhibited very low germination when
maintained on moistened filter paper. The aim of the study was to examine
the effect of GA3 treatment, different
germination temperatures, and prechilling on breaking dormancy, and to
determine the best conditions for the germination of seeds. Treatment of
the seeds with two concentrations of GA3
(0.9×10-3M and 1.8×10-3M)
promoted germination of seeds significantly more at 10°C than at
20°C. At a temperature of 10°C from 92.6% to 99.3% of seeds
germinated, and at a temperature of 20°C from 63.3% to 92.0% of the
examined seeds. The preliminary prechilling increased both the final
percentage of germination attained and also its rate of achievement.
Treatment of the GA3 solution in dimethyl
sulphoxide induced germination from 34.6% to 98.0% of tested seeds.
