Abstract

Background: TThymus plants are well-known medicinal plants and it is believed that the pharmaceutical and therapeutical properties of these plants are related to their essential oils. The quality and quantity of the essential oils, as a secondary metabolite of an aromatic plant, are directly related to the physiological state of the plant. The role of jasmonates in the plant as signal molecules in mediation and up-regulation of plant defense and secondary metabolism processes is well recognized.

Objective: With the aim of increasing the performance and stimulating secondary metabolites, this study evaluates the influence of the foliar application of MJ on essential oil content and composition of three different Thymus species, whether as an elicitor or an activator Method: The experiment was arranged in a randomized block design with MJ treatments in four levels (0, 30, 60, 100 mM) and three replications Results: Compared to the control, the essential oil content of all three species increased in all treatment levels. However, the changes in essential oil composition were different. Under MJ treatments, the amount of sesquiterpenes (especially caryophyllene oxide) increased in T. daenensis and T. fedtschenkoi. In addition, the amount of thymol in T. daenensis, thymol, and γ-terpinene in T. vulgaris increased, whereas carvacrol methyl ether in T. daenensis and p-cymene in T. vulgaris decreased.

Conclusion: IIt seems the type of plant species has a specific role in determining the response. There were no interpretable changes between treatment levels.

茉莉酸甲酯处理下 Thymus daenensis Celak.、Thymus fedtschenkoi Ronniger.和 Thymus vulgaris L. 的精油特征变化。

背景：芳香植物是众所周知的药用植物，人们认为这些植物的药用和治疗特性与其精油有关。精油作为芳香植物的次级代谢产物，其质量和数量与植物的生理状态直接相关。植物中的茉莉酸盐作为信号分子在调解和上调植物防御和次生代谢过程中的作用已得到广泛认可：本研究以提高百里香的性能和刺激次生代谢物为目的，评估了叶面喷施 MJ 对三个不同百里香品种的精油含量和组成的影响，无论是作为诱导剂还是激活剂：实验采用随机区组设计，MJ 处理分为四个水平（0、30、60、100 毫摩尔），三次重复：与对照组相比，在所有处理水平下，三种植物的精油含量都有所增加。但是，精油成分的变化有所不同。在 MJ 处理下，T. daenensis 和 T. fedtschenkoi 的倍半萜（尤其是氧化香叶醇）含量增加。此外，T. daenensis 中的百里酚、T. vulgaris 中的百里酚和γ-萜品烯含量增加，而 T. daenensis 中的香芹酚甲醚和 T. vulgaris 中的对伞花烃含量减少：看来植物种类在决定反应方面起着特殊作用。处理水平之间没有可解释的变化。
