Eff ects of Salinity and Seed Priming on Germination of Sea Fennel (Crithmum maritimum L.)

Sea fennel (Crithmum maritimum L.) is a perennial plant tolerant to the soil salinity and could be used as an alternative culture on salty soils. For successful sea fennel cultivation, it is necessary to test germinability of the seed. In this study, germination tests have been carried out on a population of sea fennel from Lopar, island of Rab, Croatia. Th e aim was to examine the eff ect of seed priming on seed germination, radicle length, radicle surface area, average diameter of radicle and radicle volume of sea fennel under diff erent salt concentrations. Seeds were primed with sodium chloride (NaCl) (50 mM) or distilled water (dH2O) during seven days aft er which its germinability and early seedling growth was tested on the germination paper treated with diff erent concentrations of NaCl (50, 100 and 150 mM) and dH2O as control. Seeds that were primed with dH2O and 50 mM NaCl solution showed the better performance than nonprimed seeds ; priming alleviated negative eff ects of low NaCl concentration.
