The Impact of Environmental Stress on the Secondary Metabolites and the Chemical Compositions of the Essential Oils from Some Medicinal Plants Used as Food Supplements

Abdelouahid Laftouhi et al.

Summary: This study investigates the effects of environmental stresses on the chemical compositions and secondary metabolite content of essential oils from Thymus vulgaris, Mentha pulegium, and Rosmarinus officinalis. The results show that the percentage of secondary metabolites increased in the second year with increased temperature and water pressure, but decreased in the fourth year due to continued temperature increase and decreased water availability. Similar trends were observed for essential oil yield. Gas chromatography analysis revealed changes in the majority of compounds in response to climate change. These findings emphasize the need for further research on the impacts of climate change on plant species and its implications for human health and well-being.

Impact of Water Stress and Temperature on Metabolites and Essential Oil of Rosmarinus officinalis (Phytochemical Screening, Extraction, and Gas Chromatography)

Abdelouahid Laftouhi et al.

Summary: Climate change has a significant impact on the content of primary and secondary metabolites as well as the yield of essential oil in Rosmarinus officinalis. The content of primary metabolites decreases with increasing temperature and decreasing precipitation, while the content of secondary metabolites increases under certain conditions. However, when temperature continues to rise and water stress further increases, the content of secondary metabolites decreases.

Field evaluation of different eco-friendly alternative control methods against Panonychus citri [Acari: Tetranychidae] spider mite and its predators in citrus orchards

Amine Assouguem et al.

Summary: Biotic stress caused by pests on citrus trees is a major problem for ecologists worldwide. This study evaluated the effectiveness of different control methods on the pest Panonychus citri and its predators. The results showed that black soap, spirodiclofen, and detergent treatments decreased the population of P. citri and had a negative impact on its predators.

Influence of Climate-Related Environmental Stresses on Economically Important Essential Oils of Mediterranean Salvia sp.

Erna Karalija et al.

Summary: Salvia is a large genus in the Lamiaceae family, with a wide distribution and diverse uses in traditional medicine and other industries. The majority of research on Salvia focuses on its chemical composition and bioactive properties, while only a few studies examine the effects of environmental factors on its commercial production. This review summarizes the essential oil composition of three economically important Salvia species from the Mediterranean region and discusses the impact of climate-related stressors on their chemical profiles.

Effect of Drought Stress on Physio-biochemical Traits and Secondary Metabolites Production in the Woody Species Pinus Halepensis Mill. At a Juvenile Development Stage

Hanene Ghazghazi et al.

Summary: This study evaluated the response of Aleppo pine seedlings to different water irrigation conditions and found that drought stress affects important metabolic processes such as transpiration, photosynthesis, and respiration in the plants. Additionally, drought stress led to changes in chlorophyll pigment content and accumulation of organic solutes. These findings are of significant importance for understanding seedlings' response to drought stress and provide valuable background knowledge for reforestation programs based on this species.

Maize and Wheat Response to Drought Stress under Varied Sulphur Fertilisation

Grzegorz Kulczycki et al.

Summary: This study examined the effects of long-lasting moderate and severe water stress and sulphur application on the growth, yield, and mineral composition of wheat and maize. The results showed that sulphur fertilization can increase wheat yield under moderate water stress, while sulphate is more effective under optimal water conditions. Severe water stress significantly reduces wheat yield, and sulphur application does not mitigate this effect. Maize experiences greater reduction in growth under severe water stress.

Changes in Essential Oil Composition, Polyphenolic Compounds and Antioxidant Capacity of Ajowan (Trachyspermum ammi L.) Populations in Response to Water Deficit

Gita Mirniyam et al.

Summary: This study evaluated the seed yield, essential oil constituents, polyphenolic composition, and antioxidant capacity of ajowan populations under different water irrigation regimes. The results showed that water stress significantly reduced both essential oil and seed yield. Different populations of ajowan also exhibited variations in chemical composition and antioxidant capacity.

PHYSIOLOGICAL REACTION AND CHEMICAL COMPOSITION OF Stachys schtschegleevii Sosn. ESSENTIAL OIL UNDER WATER DEFICIT

Hamid Mohammadi et al.

Summary: This study investigated the effects of water-deficit on S. schtschegleevii. The results showed that water-deficit had negative impacts on plant growth and photosynthetic pigments, while the essential oil content increased. Furthermore, water-deficit induced the accumulation of total phenols, proline, and oxidative substances.
