Combination Effect of NaCl Salinity and Nitrogen Form on Mineral Composition of Sunflower Plants
Open accessAbstract
The effect of two N-forms (NH4+ and NO3-) and NaCl on pattern of accumulation of some essential inorganic nutrients was examined in sunflower (Helianthus annuus L.) cv. Hisun 33. Eight-day-old plants of were subjected for 21 d to Hoagland's nutrient solution containing 8 mM N as NH4+ or NO3., and salinized with and addition of NaCl to the growth medium had no significant effect on total leaf N. However, root N of NH4-supplied plants decreased significantly with increase in NaCl concentration, whereas that of NO3-supplied plants remained unaffected. There was no significant effect of NaCl on leaf or root P, but the NO3-supplied plants had significa concentration of leaf P than that of NH4-supplied plants at varying salt treatments. Salinity of the rooting med did not show any significant effect on Na+ concentrations of leaves or roots of plants subjected to two differen N. NH4-treated plants generally had greater concentrations of Cl- in leaves and roots and lower K+ content in leaves than NO3-supplied plants. Ca2+ concentrations of leaves and roots and Mg2+ concentrations of leaves decreased in NH4-supplied plants due to NaCl, but they remained unaffected in NO3-treated plants.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
