芝麻籽油的脂肪酸组成决定了它的商业价值，干旱胁迫和基因型可能会影响芝麻籽加工商提取的油的质量和数量。因此，在位于伊朗伊斯法罕的田地中进行本实验，以确定三种灌溉制度[55%（I（1），作为对照）、75%（I（2））和85%（I（3））的土壤有效水消耗]对十种芝麻基因型的油含量和组成的影响（Isfahan 4，沙赫雷扎，Borazjan，Ahvaz，Kal，Shiraz，Markazi，Ardestan，Ultan and Isfahan 1）.在2010-2012年期间测定了种子油含量和棕榈酸、亚油酸、亚麻酸、硬脂酸和油酸含量。I（1）灌溉条件下的沙赫雷扎、I（2）灌溉条件下的沙赫雷扎和Ardestan以及I（3）灌溉条件下的Isfanahan 4的含油量最高，而I（1）和I（2）灌溉条件下的Kal以及I（3）灌溉条件下的Isfahan 4的含油量最高。Ultan在所有三种灌溉制度下的棕榈酸含量最低，而Isfahan 4在I（2）和I（3）下的棕榈酸含量降低最多。在I（1）、I（2）和I（3）灌溉制度下，Borazjan的硬脂酸含量最低，亚油酸含量最高。Kal、Kal和Ardestan、Ardestan和Isfahan 1分别在I（1）、I（2）和I（3）条件下产生最高的油酸。I（1）和I（2）处理下的沙赫雷扎和I（3）处理下的伊斯法罕4号亚麻酸含量最高。结果表明，芝麻油含量和组成具有基因型-干旱特异性，从芝麻油产量、饱和脂肪酸含量的减少率和不饱和脂肪酸含量的增加率来看，Isfahan 4号是最耐旱的基因型。
The fatty acid composition of sesame seed oil determines its commercial value, and drought stress and genotype may affect both the quality and quantity of oil that is extractable by sesame seed processors. Therefore, this experiment was conducted in a field located in Isfahan, Iran, to determine the effect of three irrigation regimes [55 % (I (1), as control), 75 % (I (2)) and 85 % (I (3)) of depletion of soil available water] on the oil content and composition of ten sesame genotypes (Isfahan4, Shahreza, Borazjan, Ahvaz, Kal, Shiraz, Markazi, Ardestan, Ultan and Isfahan1). Seed oil content and palmitic, linoleic, linolenic, stearic and oleic acid contents were determined during 2010-2012. Shahreza under I (1), Shahreza and Ardestan under I (2) and Isfanahan4 under I (3) irrigation regimes produced the highest oil content, while Kal under I (1) and I (2) and Isfahan4 under I (3) irrigation regimes produced the highest oil yield. Ultan had the lowest palmitic acid content under all three irrigation regimes, while Isfahan4 had the highest reduction in palmitic acid content under I (2) and I (3). Borazjan produced the lowest stearic and highest linoleic acid contents under the I (1), I (2) and I (3) irrigation regimes. Kal, Kal and Ardestan, and Ardestan and Isfahan1 produced the highest oleic acid under I (1), I (2) and I (3), respectively. Shahreza under I (1) and I (2) and Isfahan4 under I (3) had the highest linolenic acid content. The results showed that the sesame oil content and composition were genotype-drought level specific, and based on oil yield production and percent reduction in saturated and increase in unsaturated fatty acid contents, Isfahan4 was the most drought-tolerant genotype.
