Abstract The effect of foliar application of Salcylic acid (SA) on grain and oil yield of Cuminum cyminum L. in field condition were investigated in the region of Fasa (Fars province, Iran). Treatments comprised 0.1, 0.4, 0.7 and 1.1 mM SA applied to plants. Results indicated that the highest values of oil content (5.03 % v/w) and 1000 grain weight (3.20 g) were obtained from the application of 1.1 mM SA, however, no significant differences were found between SA levels on grain yield. The results of EO analysis showed that the amounts of β-pinene (2.36-3.48 %), ρ-cymene (7.55-9.19 %), γ-terpinene (9.61-12.37 %), γ-terpinene-7-al (24.47-31.96 %) and cumin aldehyde (24.60-29.19 %) as major oil components increased gradually with increasing SA levels, however, the amounts of cis-sabinene hydrate (0.04-0.06 %), trans-sabinene hydrate (0.12-0.17 %), terpinene-4-ol (0.16-0.28 %) and γ-terpinene-7-al (24.47-31.96 %) decreased with increasing SA levels.

水杨酸对小茴香精油含量及成分的影响。

摘要 在Fasa（伊朗法尔斯省）地区研究了叶面喷施水杨酸（SA）对田间条件下Cuminum cyminum L. 粮油产量的影响。处理包括应用于植物的 0.1、0.4、0.7 和 1.1 mM SA。结果表明，应用 1.1 mM SA 获得了最高的含油量 (5.03 % v/w) 和 1000 粒重 (3.20 g)，然而，未发现 SA 水平之间对谷物产量的显着差异。EO分析结果表明，β-蒎烯（2.36-3.48%）、ρ-伞花烃（7.55-9.19%）、γ-萜品烯（9.61-12.37%）、γ-萜品烯-7-al（24.47- 31.96 %) 和孜然醛 (24.60-29.19 %) 作为主要油成分随着 SA 水平的增加而逐渐增加，然而，顺式柞烯水合物 (0.04-0.06 %)、反式柞树烯水合物 (0.12-0.17 %) 的量，
