Most of the studies on the effects of salinity stress are conducted on ornamental bedding plants and perennials but little is known on flower bulbs response to this stress factor. Ornithogalum saundersiae is an attractive bulbous plant recommended for growing in pots, gardens and green areas. The study conducted in the years 2013–2014 investigated the effects of NaCl on the growth, flowering, photosynthetic activity, pigment content, and macro- and micronutrient content in the leaves of O. saundersiae. The plants were grown in pots in a plastic tunnel. NaCl was applied once a week for six weeks at concentration of 100 mM or 200 mM. The salt treatment did not cause chlorosis and did not affect flowering rate and number of inflorescences. The plants exposed to salinity stress had lower fresh weight of leaves, inflorescences and bulbs and their flowering began later than in the control plants. Photosynthesis and transpiration intensity decreased as NaCl concentration increased. The content of chlorophyll and carotenoids in NaCl treated plants was significantly higher than in the control plants. Salinity stress increased the leaf content of nitrogen, potassium, sodium and chlorine and reduced the concentration of calcium, zinc and iron.
