| Abstract: | Sunflower seeds (Helianthus annuus L., cv. Dwarf) were grown with distilled water only or increasingly saline solutions (NaCl) to determine the influence of salinity on seedling growth and on the distribution of mineral nutrients obtained exclusively from cotyledons. Seedling growth was decreased by moderate (50mM) and high (100mM) concentrations of NaCl in the growth solution. Salinity generally decreased mineral transport (especially Fe, Mn, Mg, and Ca) from seed to seedling, except for K. Transport of Fe, Mg, and Ca to the aerial part was also markedly reduced. |
