Thus, two experiments were conducted to evaluate the response of scorzonera to salinity. In the first experiment, seed germination and seedling growth were investigated under osmotic potentials down to \u20131.21 MPa using NaCl or iso-osmotic polyethylene glycol (PEG) solutions. Results of PEG treatments show that osmotic potential alone reduces germination and seedling growth while on NaCl reductions were much lower. Ionic effects of NaCl are stimulatory and clearly counteract osmotic effects. Most seeds completed germination after being transferred from PEG to distilled water. Conversely, on NaCl, recovery results essentially from more time allowed for seeds to complete germination. In the second experiment, young plantlets were treated with NaCl solutions up to 250 mmol\u00b7L<jats:sup>\u22121<\/jats:sup>. In general, plantlets were insensitive to NaCl except for a concentration-dependent increase of relative chlorophyll content, suggesting that scorzonera tolerance to NaCl might depend upon nitrogen availability. Altogether, results support the conclusion that scorzonera may be a naturally salt tolerant species able to accumulate and sequester NaCl, with its tolerance increasing as plants grow older. <\/jats:p>","DOI":"10.1139\/cjb-2015-0015","type":"journal-article","created":{"date-parts":[[2015,7,9]],"date-time":"2015-07-09T17:49:18Z","timestamp":1436464158000},"page":"485-496","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Ionic effects of NaCl counter osmotic inhibition of germination and seedling growth of <i>Scorzonera hispanica<\/i> and subsequent plantlet growth is not affected by salt"],"prefix":"10.1139","volume":"93","author":[{"given":"Lu\u00eds Silva","family":"Dias","sequence":"first","affiliation":[{"name":"Departamento de Biologia, Escola de Ci\u00eancias e Tecnologia, Universidade de \u00c9vora, \u00c9vora, Portugal."}]},{"given":"Alexandra Soveral","family":"Dias","sequence":"additional","affiliation":[{"name":"Departamento de Biologia, Escola de Ci\u00eancias e Tecnologia, Universidade de \u00c9vora, \u00c9vora, Portugal."}]},{"given":"Isabel Pires","family":"Pereira","sequence":"additional","affiliation":[{"name":"Departamento de Biologia, Escola de Ci\u00eancias e Tecnologia, Universidade de \u00c9vora, \u00c9vora, Portugal."},{"name":"Instituto de Ci\u00eancias Agr\u00e1rias e Ambientais Mediterr\u00e2nicas, Universidade de \u00c9vora, \u00c9vora, Portugal."}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1139\/b02-008"},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02894635"},{"issue":"2","key":"refg3\/ref3","first-page":"153","volume":"10","author":"B\u0142a\u017cewicz-Wo\u017aniak M.","year":"2011","journal-title":"Acta Sci.
