Abstract

Thymus spp. is one of the most important medicinal plants widely used in food, pharmaceutical, and cosmetic industries. In this research, different ecotypes of three Thymus species including T. daenensis, T. kotschyanus and T. lancifolius native to Iran were compared to two commercial cultivars of T. vulgaris (i.e. 'Varico 3' and 'Deutscher Winter') under identical conditions. Based on the results, there was a remarkable diversity among different ecotypes of Thymus species. The highest plant dry weight was found in T. daenensis (Malayer 2), T. kotschyanus (Azerbaijan gharbi), and T. lancifolius (Fars). The highest thymol percentage (>75%) was obtained by T. daenensis. The ecotype of Ilam belonging to T. daenensis gained highest essential oil percentage (7.83%). In all ecotypes of T. daenensis, thymol was the major constituent in their essential oil. Five chemotypes of citral, carvacrol-thymol, thymol-carvacrol, p-cymene-carvacrol, and geranyl acetate-citral were found in T. kotschyanus ecotypes, while four chemotypes of thymol, α-terpineol-linalool, carvacrol-thymol and thymol- geraniol were identified for T. lancifolius. In addition, in terms of growth, yield, and phytochemical traits, the elite genotypes within ecotypes were selected. Elite ecotypes and genotypes detected during this research could be used in Thymus breeding programs.

伊朗原产胸腺生态型的形态和植物化学筛选，以选择优良基因型

胸腺草是一种重要的药用植物，广泛应用于食品、医药、化妆品等行业。本研究以伊朗原产的三种胸腺(T. daenensis)、T. kotschyanus和T. lancifolius)的不同生态型与两种商业品种T. vulgaris (T. vulgaris)进行了比较。“Varico 3”和“Deutscher Winter”)在相同的条件下。结果表明，不同生态型胸腺属植物存在显著的多样性。植物干重最高的品种是T. daenensis (Malayer 2)、T. kotschyanus (Azerbaijan gharbi)和T. lancifolius (Fars)。丹参百里香酚含量最高(>75%)。daenensis的Ilam生态型精油含量最高，为7.83%。在所有生态型中，百里香酚是其精油的主要成分。香茅生态型共鉴定出香茅醛、香茅醇-百里香酚、香茅醇-香茅醇、对花香茅醇-香茅醇和香叶醇-乙酸香叶醇5种化学型，而香茅生态型共鉴定出香茅醛、α-松油醇-芳醇、香茅醇-百里香酚和香茅醇-香叶醇4种化学型。此外，在生长、产量和植物化学性状方面，选择了生态型中的优秀基因型。本研究检测到的优良生态型和基因型可用于胸腺育种。

期刊介绍： The Journal of Applied Botany and Food Quality is the Open Access journal of the German Society for Quality Research on Plant Foods and the Section Applied Botany of the German Botanical Society. It provides a platform for scientists to disseminate recent results of applied plant research in plant physiology and plant ecology, plant biotechnology, plant breeding and cultivation, phytomedicine, plant nutrition, plant stress and resistance, plant microbiology, plant analysis (including -omics techniques), and plant food chemistry. The articles have a clear focus on botanical and plant quality aspects and contain new and innovative information based on state-of-the-art methodologies.
