“…In the present study, oregano showed the maximum yield of fresh and dry weight under shade-enclosure. Similar results were found by Murillo-Amador et al (2013) in oregano and thyme. In the present study, leaf area reached maximum values when plants were grown under shade-enclosure environment ( Table 2 ).…”

“…Recently, Murillo-Amador et al (2013) found that for oregano and thyme species, all variables measured under shade-enclosure conditions were more favorable than open-field condition. The SMP under shade-enclosure, showed less negative values than open-field condition, probably because the soil under shade-enclosure condition dry more slowly as water is retained, and in addition this is related with the higher Gs, E , and A in oregano plants grown under this condition but with similar WU E than open-field, maintaining less negative LWP under shade-enclosure and therefore slightly higher RWC values in those plants grown under shade-enclosure.…”

“…In Mexico, the state of Baja California Sur is the main producer of oregano; however, there is little or no research evaluating the local crops grown here ( Murillo-Amador et al, 2013 ). This crop is mainly grown in open-field in an organic system where the plants are fertilized, irrigated and protected from pests and diseases throughout the growing period following standards accepted for cultivation of organic agriculture in this region ( Murillo-Amador et al, 2006 , 2010 , 2013 ). Great attention has been paid toward the application of bio-organic farming to avoid the heavy use of agrochemical that has resulted in numerous environmental difficulties ( Lampkin, 1999 ).…”

Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and morphometric characteristics in one oregano (Origanum vulgare L.) cultivar. In this study a completely randomized block design was used with four replications and evaluated for photosynthetic and transpiration rate, stomatal conductance, chlorophyll, leaf area and temperature, aerial and roots fresh and dry biomass, fresh and dry yield. The results showed that oregano adapted best to the shade-enclosure with increase yield of fresh and dry leaf weight of 165% and 118%, respectively, when compared to open-field. Also, higher doses of bocashi improved yield in both environments but more so in shade-enclosure. Soil moisture retention was higher in shade-enclosure which was reflected in physiological variables for soil matric potential, transpiration, stomatal conductivity, photosynthesis being significantly higher in shade-enclosure compared to open-field, thus improving yield. It seems that oregano plants can be grown and perform better under shade-enclosure than open-field and bocashi is a suitable organic fertilizer.

“…The photosynthetic pigments from the leaves of the three groups were measured (chlorophylls, pheophytins, and carotenoids). Total chlorophylls and carotenoid concentration of the LT group was significantly higher (547.40 and 53.31 µg/g FW, respectively) than in NT group (349.30 and 36.86 µg/g FW, respectively), indicating that the photosynthetic pigment levels might contribute to the difference in the photosynthetic capacity among the temperature conditions [ 17 , 18 ]. In contrast, total content of pheophytins in LT plants remained almost unchanged.…”

The influence of climatic factors, e.g., low temperature, on the phytochemical composition and bioactivity of the arctic plant Dracocephalum palmatum Steph. ax Willd. (palmate dragonhead), a traditional food and medical herb of Northern Siberia, was investigated. D. palmatum seedlings were grown in a greenhouse experiment at normal (20 °C, NT) and low (1 °C, LT) temperature levels and five groups of components that were lipophilic and hydrophilic in nature were characterized. The analyses indicated that D. palmatum under NT demonstrates high content of photosynthetic pigments, specific fatty acid (FA) profile with domination of saturated FA (53.3%) and the essential oil with trans-pinocamphone as a main component (37.9%). Phenolic compounds were identified using a combination of high performance liquid chromatography with diode array detection and electrospray ionization mass-spectrometric detection (HPLC-DAD-ESI-MS) techniques, as well as free carbohydrates and water soluble polysaccharides. For the first time, it was established that the cold acclimation of D. palmatum seedlings resulted in various changes in physiological and biochemical parameters such as membrane permeability, photosynthetic potential, membrane fluidity, leaf surface secretory function, reactive oxygen species–antioxidant balance, osmoregulator content and cell wall polymers. In brief, results showed that the adaptive strategy of D. palmatum under LT was realized on the accumulation of membrane or surface components with more fluid properties (unsaturated FA and essential oils), antioxidants (phenolic compounds and enzymes), osmoprotectants (free sugars) and cell wall components (polysaccharides). In addition, the occurrence of unusual flavonoids including two new isomeric malonyl esters of eriodictyol-7-O-glucoside was found in LT samples. Data thus obtained allow improving our understanding of ecophysiological mechanisms of cold adaptation of arctic plants.

“…Origanum vulgare L. (oregano) and Thymus vulgaris L. (thyme) are aromatic spice herbs belonging to the Lamiaceae family. They are native to the Mediterranean region and neighboring countries [ 16 , 17 ], and in folk medicine, they have been used as remedies to treat respiratory disorders (e.g., coughs and bronchitis) as expectorants, dyspepsia as well as urinary tracts disorders [ 16 , 17 , 18 , 19 ]. Although the principal components of oregano and thyme EOs are carvacrol and thymol, respectively, their chemical compositions vary depending on geographical region and season of collection [ 20 ].…”

Combinatory action of antimicrobial agents such as essential oils (EOs) show to be an effective strategy to overcome the problem with increasing antibiotic resistance of microorganisms, including Staphylococcus aureus. The objective of this study was to evaluate in vitro antimicrobial interactions between Origanum vulgare and Thymus vulgaris EOs against various S.aureus strains in both liquid and vapor phases using the broth volatilization checkerboard method. Fractional inhibitory concentrations (FICs) were determined for both liquid and vapor phases, and the composition of EOs was analyzed by gas chromatography-mass spectrometry using dual-column/dual-detector gas chromatograph. Results of oregano and thyme EOs combination showed additive effects against all S. aureus strains in both phases. In several cases, sums of FICs were lower than 0.6, which can be considered a strong additive interaction. The lowest FICs obtained were 0.53 in the liquid phase and 0.59 in the gaseous phase. Chemical analysis showed that both EOs were composed of many compounds, including carvacrol, thymol, γ-terpinene, and p-cymene. This is the first report on oregano and thyme EOs interactions against S. aureus in the vapor phase. It also confirms the accuracy of the broth volatilization checkerboard method for the evaluation of combinatory antimicrobial effects of EOs in the vapor phase.
