The research was
conducted to determine the effect of gibberellic acid pre-treatments on
germination of Echinacea purpurea
seeds under salt stress. In
the study, three different gibberellic acid concentrations (0, 100, 200 and 300
ppm) were pre-treated. Seeds planted in petri dishes
were left to germinate after salt applications at 0, 50 and 100 mM (NaCl)
concentrations. Responses of echinacea
to priming and salt stress treatments were observed on the bases of some growth
and viability (radicle and hypocotyl length, radicle fresh and dry weight,
hypocotyl fresh and dry weight, germination power, germination speed, mean
germination time, germination and sensitivity index) parameters.
According to the result
of the research; when the salt concentrations increase, the germination and growth
parameters of echinacea seeds were
inhibited. It was conducted determined that increasing doses of gibberellic
acid pre-treatments had significant and positive effects on the germination and
growth parameters of echinacea seeds
under salt stress conditions. In physiological enhancement of echinacea seeds,
the best results were obtained from the 300 ppm GA3+0 mM (control) salt combination.
