Sažetak
Gentiana lutea L. is a medicinal plant growing on the Balkan Peninsula mountain regions. Due to the uncontrolled harvest of its roots, it is under protection as an endangered species in Croatia. The over exploitation of this wild species can lead to depletion in its natural habitat. Majority of alpine species have dormant seeds, such is the case for yellow gentian, which can be a disadvantage in nursery plant production. The aim of this research was to evaluate seeds of two yellow gentian accessions from National Park Učka in their morphological characteristics, as well as testing the effect of different concentrations of gibberellic acid (0 - 1000 mg/L GA3) and cold moist stratification (30 or 60 days at 4 °C) in breaking seed dormancy. The seeds were germinated at constant temperature of 15 °C and 12h photoperiod during 30 days in the growth chamber conditions. We found significant differences among accessions in seed morphology as well as final germination percentage. Final germination percentage was highest in non-stratified seeds treated with 100 to 500 mg/L GA3 compared to other treatments. Significant interaction between treatments and accessions was found. Final germination percentages ranged from 0 to 74%. According to our results it seems that application of GA3 is sufficient for breaking seed dormancy of yellow gentian seeds.
