Kvalitet semena uljane repice u uslovima sonog stresa

Abstract

Osetljivost uljane repice prema količini soli u zemljištu nije ista u svim fazama njenog porasta. Najosetljivije su biljke u fazi klijanja i nicanja. Cilj ovog istraživanja je bio da se utvrdi uticaj različitih koncentracija soli NaCl (0 mmol/l,125 mmol/l,175 mmol/l,250 mmol/l) na klijavost semena, srednje vreme klijanja semena, vigor indeks, dužinu ponika i svežu masu ponika kod semena tri genotipa uljane repice (Anna, Slavica, Ilia). Iz dobijenih rezultata se uočava da niže koncentracije NaCl biljke mogu da tolerišu i one ne utiču negativno, dok visoke koncentracije ispoljavaju negativan uticaj na ispitivane parametare.

Sensitivity of oilrape towards the quantity of the salt in the soil is not the same in all its growth stages. The most sensitive are the plants in the initial stages – germination and emergence. The aim of this investigation was to determine the influence of various NaCl concentrations (0 mmol/l,125 mmol/l,175 mmol/l,250 mmol/l) to seed germination, means daily germination seed, vigor index, seedling length and fresh mass of seedling in the seed of three oilrape genotypes (Anna, Slavica and Ilia). From the obtained results it can be seen that plants can tolerate lower NaCl concentrations, which have no negative effects, while high NaCl concentrations exert negative effects on the tested parameters.
