- Although not essential for most plants, sodium (Na +) can be beneficial to plants in many conditions, particularly when potassium (K +) is deficient. As such it can be regarded a ‘non-essential’ or ‘functional’ nutrient.
Oct 22, 2013 · There are several reasons why salinity decreases plant growth (Flowers and Colmer, 2008): First, high ambient concentrations of inorganics such as Na + and Cl – lower the water potential and hence create osmotic stress. A logical response to counter this trauma is the uptake of these ions themselves, a strategy that is successfully employed ...

Jun 22, 2013 · Sodium (Na +) is one of the most intensely researched ions in plant biology and has attained a reputation for its toxic qualities. Following the principle of Theophrastus Bombastus von Hohenheim (Paracelsus), Na + is, however, beneficial to many species at lower levels of supply, and in some, such as certain C4 species, indeed essential.

Sep 23, 2021 · With increasing sodium, plants have been shown to decrease biomass accumulation; increase osmotic, oxidative, and ionic stress responses; and arrest growth due to changes in cellular biochemistry (Maathuis, 2014; Zhao et al., 2020).

Control of Na + fluxes is therefore crucial and indeed, research shows that the divergence between salt tolerant and salt sensitive plants is not due to a variation in transporter types but rather originates in the control of uptake and internal Na + fluxes.
Aug 1, 2013 · Regardless, in order to tolerate salt, plants must regulate intracellular Na + homeostasis in order to minimize cytotoxic effects of the ion and for osmotic adjustment (Flowers et al., 1977, Flowers et al., 1986, Niu et al., 1995, Flowers and Colmer, 2008, Munns and Tester, 2008).
Plants can absorb inorganic nutrients and water through their root system, and carbon dioxide from the environment. The combination of organic compounds, along with water, carbon dioxide, and sunlight, produce the energy that allows plants to grow. Inorganic compounds form the majority of the soil solution. Plants access water though the soil.
