“…One of the Na effects on the promotion of plant growth consists of the replacement of the physiological functions of K cin plants by Na (17,20). In the present experiment, the foliar K, Ca, and Mg concentrations were not appreciably low in all the Na treatments.…”

“…Such seems to be the situation with respect to mangels, sugar beets, Swiss chard, table beets, celery and turnips grown on peat soils [2]. That sodium is essential with certain crops under certain conditions is highly probable [11][12][13]. Sodium is an activator of transport ATP-ases in animals and possibly also in plants.…”

ABSTRACT. Levels of sodium, potassium, calcium and magnesium were determined in plant organs (bud, flowers, fruit, seed, leaves, stems, roots, cobs, styles, shaft, grains and efflorescences) of three Fadama farms located in Ifaki-Ekiti, Ado-Ekiti and Ikere-Ekiti of Ekiti State, Nigeria. The highest levels of Mg, K, Na and Ca were obtained in the bud of Hibiscus esculentus with respective values (ppm dry weight, ppm DW) of 4397, 2983, 3928 and 1622; this was closely followed by their levels in Lycopersicon esculentum root: Mg (2734), K (1079), Na (2111) and Ca (678). The levels of all the elements were highly varied in the anatomical parts of each plant and between the various plants. The index of bioaccumulation (ratio in plants/soil) was recorded for all the elements with all values falling within 1-10 showing that the degree of accumulation was intensive. The overall levels of the elements were Mg > Na > K > Ca.

“…Aside from growth (improved root and shoot biomass) and yield, results in early studies were often reported as readily visible changes, such as improvement in colour (i.e. greener leaves) and its maintenance in later growth stages, and, related to this, less pronounced manifestations of nutrient deficiency (chlorosis or necrosis), or greater "gloss" on leaves, suggesting an increase in cuticular wax formation (Harmer and Benne 1945;Brownell and Crossland 1972). Other reports have commented on the taste and texture of crops grown with additions of sodium (Harmer and Benne 1945;Truog 1953;Zhang and Blumwald 2001).…”

“…The paradigm that C 4 species benefit particularly substantially, and indeed in many, albeit not all, cases require Na + as an essential nutrient, is now widely accepted (Harmer and Benne 1945;Barbier and Chambannes 1951;Brownell and Wood 1957;Brownell 1965;Alekseev and Abdurakhamanov 1966;Brownell and Jackman 1966;Brownell and Crossland 1972;Marschner 1995;Pessarakli and Marcum 2000;Pessarakli 2001;Subbarao et al 2003). Important exceptions include the leading C 4 crops corn and sorghum, which have been shown not to benefit from Na + addition (Ohta et al 1988;Ohnishi et al 1990;Subbarao et al 2003).…”

Sodium as nutrient and toxicant

et al. 2013

Background 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. Scope Here, we review the ion's divergent roles as a nutrient and toxicant, focusing on growth responses, membrane transport, stomatal function, and paradigms of ion accumulation and sequestration. We examine connections between the nutritional and toxic roles throughout, and place special emphasis on the relationship of Na + to plant potassium (K + ) relations and homeostasis. Conclusions Our review investigates intriguing connections and disconnections between Na + nutrition and toxicity, and concludes that several leading paradigms in the field, such as on the roles of Na + influx and tissue accumulation or the cytosolic K + /Na + ratio in the development of toxicity, are currently insufficiently substantiated and require a new, critical approach.
