Response of Thymus vulgaris L. to coronatine, methyl jasmonate, and cyclodextrin at different levels of moisture supply under greenhouse conditions. (English)

Medicinal plants are a rich and valuable source of secondary metabolites that are strongly influenced by the environmental factors, especially drought stress. In this regard, a greenhouse experiment was conducted on Thymus vulgaris L. as split plots in a randomized complete block design with three replications. The main plot included three levels of moisture supply (40, 65, and 90% of potting soil field capacity (FC)) and the sub-plot was the elicitors levels including (1) control: without elicitor, (2) 150 μM cyclodextrin (CYC), (3) 75 nM coronatine (COR) + 150 μM CYC, (4) 150 nM COR + 150 μM CYC, (5) 150 μM methyl jasmonate (MJ) + 150 μM CYC, and (6) 300 μM MJ + 150 μM CYC. Except for the essential oil percentage, the other traits including the leaves proline content, electrolyte leakage, relative water content, plant height, canopy diameter, dry and fresh weight of shoots, dry weight of leaves and stems, and weight of essential oil had a very significant correlation with each other. The highest amount of leaves proline was obtained form the interaction of elicitors (levels 4 and 6) and the 40% FC level of moisture supply (3.88 and 3.94 μmol g-1 fresh leaf weight, respectively). The highest amount of plant height (28.3 cm), canopy diameter (17 cm), and relative water content (79%) was observed at the 90% FC level of moisture supply. The highest percentage of essential oil was obtained in the treatment of non-application of elicitor (2.67%) and the highest essential oil weight per plant (0.046 g plant^-1) was observed in the treatment of non-application of elicitor at the 65% FC level of moisture supply. The mild stress increased the essential oil yield and the elicitor treatments decreased it. [ABSTRACT FROM AUTHOR]
