“…The 3.35 dS m -1 treatment resulted in an intermediate seed number, but that number was also significantly higher than the lowest EC treatment. These positive results are clearly contrary to those obtained by [30], who, by increasing the EC of the nutrient solution by means of NaCl (of similar EC salinity to our treatment of 3.35 dS m -1 ), reported substantially decreased seed production and did not obtain many seeds with their treatments of higher salinities (similar to or greater than our treatment of 4.50 dS m -1 ). This difference in results could be justified because it is well known that a greater benefit is achieved in productivity—at equal ECs of the nutrient solution—when these are obtained with a proportional increase of the macronutrients compared to when NaCl is added [13, 32, 33].…”

“…The number of viable seeds showed similar behaviour. Our EC control treatment (2.20 dS m -1 ) showed a much higher seed productivity (13.97 g plant -1 ) than the non-saline treatment recorded by [30] (1.15 g plant -1 ) (Table 3). The highest EC treatments, 3.35 and 4.50 dS m -1 , generated significant increases of 27 and 40% higher than the previous EC level, respectively.…”

“…Jaffel-Hamza et al [29], who increased the EC from a standard nutrient solution with NaCl, recorded similar results with low salinity (25 mM), while they reported that a 5 dS m -1 increase above this EC resulted in a significant decrease in the vegetative growth of leaves, stems, roots and buds. In contrast, these same authors [30] recorded a significant reduction in the production of biomass from a nutrient solution with the addition of 25 mM NaCl, as also recorded by [31] from an EC of 5 dS m -1 .…”

Effects of the electrical conductivity of a soilless culture system on gamma linolenic acid levels in borage seed oil

et al. 2019

Borage is a well-known plant of great importance in human nutrition and health. Expanding knowledge of particular plants that have anti-cancer products is a global concern. There is substantial information regarding the benefits, presence and extraction of gamma linolenic acid (GLA; 18:3n6) in different plants around the world, especially in borage seeds. However, there is little information concerning the effects of the salinity of the nutrient solution on the growth and presence of GLA in borage seeds. The objective of this work was to determine the optimal salinity of the nutrient solution for obtaining GLA in soilless cultivation systems. Borage plants were grown in coconut fibre and provided three treatments of nutrient solution of 2.20, 3.35 and 4.50 dS m -1 , increasing solution salinity with the standard nutrient solution of concentrated macronutrients as a reference. Vegetative growth, seed production and GLA ratio were measured. The results of vegetative development and GLA production doubled and tripled with the increase in salinity of the nutrient solution, respectively.

“…In agreement with that, Møller et al (2007) illustrate that salt tolerant plants may protect against the oxidative effects of salts through restructuring their membranes with less polyunsaturated fatty acids. Further support is the fact that lipid peroxidation greatly increases in salt sensitive plants under salinity (Hajlaoui et al, 2009;Jaffel-Hamza et al, 2013). Accumulation of 18:2 rather than 18:3 in the sensitive cultivar was related to more lipid peroxidation and an alteration in fatty acid desaturase activity in saline environment.…”

“…The halophyte vegetative organs of Suaeda altissima treated with 250 mM NaCl had induced fatty acid saturation and elongation of their chain, which was considered as an adaptive response to reduce membrane permeability for ions under salt imposition (Tsydendambaev et al, 2013). Moreover, membrane polyunsaturated fatty acids as well as total fatty acids were decreased whereas saturated fatty acids were increased in borage leaves under high salinity, which was considered as an adaptation to salinity (Jaffel-Hamza et al, 2013). The authors indicate that the decrease in fatty acid unsaturation under salt was due to a reduction in the desaturase activity, which suggested as an adaptive feature to salinity.…”

Role of the Plasma Membrane in Saline Conditions: Lipids and Proteins

The PM is believed to be one facet of the cellular mechanisms involved in adaptation to saline conditions. Alterations in the PM components in response to salinity are therefore anticipated to contribute to plant salt tolerance. The review provides a comprehensive overview of the recent findings describing the crucial roles of the PM components in plant acclimation to salt stress. The responses of the PM proteins and lipids to salinity in contrasting species/cultivars were therefore discussed. The relationship between alterations in the lipids and proteins of the PM and tolerance to salt stress is also addressed. Several lines of evidence were presented demonstrating correlation of modifying the PM composition with adaptation of plants to high salinity. Even if contradictory results have been observed, the roles of the PM lipids and proteins appeared to be of great importance for tolerance to high salinity. Despite the promising results, more research should be carried out at the molecular level to further evaluate the roles of some of the PM components in salt tolerance.

Thirty Boraginaceae species from different tribes were evaluated in a search of γ-linolenic (GLA, 18:3n-6) and stearidonic acid (SDA, 18:4n-3)-rich oils. The high GLA percentages were found in the seed oils of Symphytum bulbosum and S. tuberosum subsp. tuberosum (27.6 and 27.2 % of total fatty acids (FA)), which are unusually high values for GLA-oils in the current literature. On the whole seed, noticeable GLA percentages were found in S. grandiflorum, S. tuberosum subsp. tuberosum and Borago officinalis (7.43, 4.90, and 4.51 g/100 g, respectively). The main SDA-taxa detected in this study were Buglossoides arvensis, B. incrassata and Glandora oleifolia (21.3, 18.9, and 16.3 % of total fatty acids). On total seed weight, Glandora rosmarinifolia showed the highest SDA content (3.57 g/100 g). Finally, the higher FA contents were found in S. grandiflorum and Paramoltkia doerfleri seeds (35.2 and 37.0 g/100 g, respectively). Principal component analysis showed that similarities in FA profiles allow grouping species as botanical criteria for Boraginaceae tribes do, while the FA groupings confirm the metabolic activities of desaturase and elongase enzymes. Data on the FA composition of the seed oils analyzed here suggest their potential use as functional foods and can be considered as novel sources of SDA and GLA.
