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.
琉璃苣是一种广为人知的植物，对人类营养和健康具有重要意义。扩大对具有抗癌产品的特定植物的认识是全球关注的问题。关于不同植物中 γ-亚麻酸（GLA；18:3n6）的益处、存在和提取，特别是在琉璃苣种子中，有大量信息。然而，关于营养液盐度对琉璃苣种子中 GLA 生长和存在的影响的信息却很少。这项工作的目的是确定无土栽培系统中获得 GLA 的最佳营养液盐度。在椰子纤维中种植琉璃苣植物，并提供三种营养液处理，浓度分别为 2.20、3.35 和 4.50 dS m-1，营养液盐度随浓缩大量营养素的标准营养液而增加。测量了营养生长、种子生产和 GLA 比例。营养生长和 GLA 产量的结果分别增加了一倍和两倍，随着营养液盐度的增加而增加。
