摘要：Total lipids and fatty acids of black seed/black cumin (Nigella sativa L.) have antimicrobial activities. Where as saline irrigation water (SIW) caused a dramatic effect on performance and physiological processes of agricultural crops. Selected tolerated plants to salinity stress is a focus of research and industry since salinity stress and total lipids (or fatty acids) yield are of major concern to increase total lipids production in arid and semi-arid regions. So, in this study, the lipids and fatty acids constituents of black cumin were determined under salinity stress factor Nigella sativa L. plants were subjected to different doses (0.25, 1, 2, and 3 g l−1) of SIW. Evaluation of total lipids and fatty acids of N. sativa seeds were reported during two successive seasons. The highest amounts of total lipids (%) were recorded under the dose of 2 g l−1 with the values of 30.4 and 28.6% during both seasons. The Maximum yields of total lipids were obtained in the 1gl-1 treatment with the values of 3.4 and 3.3 g Plant -1. The greatest values (55.3, 22.1 and 55.3, 19.9) of the main fatty acids (linoleic and oleic) were recorded with 3 g l−1 in both the seasons. The high accumulation in N. sativa lipid and fatty acids composition under salinity stress levels may be due to its effect of salinity on enzyme activity and metabolism of lipid production.
