Various kinds of abiotic stresses are prospective harmful to the plants like temperature, salinity, drought, flood, radiation, chemical as well as mechanical stresses which affect the concentration of various secondary plant products and reduces the yield of the crops. One of the most significant abiotic stresses is drought which affect the growth and development of the plant by reducing the available water level in the soil. In most of the higher plants primary metabolite is responsible for the synthesis of secondary metabolites and the concentrations of various secondary plant products are strongly dependent on the growing conditions. The significant application of secondary metabolite in nutritive, medicinal, food additive, flavor, pharmaceutical and industrially important pharmaceutical. In most of the cases, presence of abiotic stresses the production of secondary metabolite is enhances in the aromatic and medicinally important higher plants, which rise up the phytomedicine production and also promote the essential oil production in aromatic plant. We can cooperate in project with this objective 1- Study the effect of abiotic stresses on Medicinal and aromatic plants 2- Use some elicitors (biotic and abiotic) to increase plants tolerance 3- Select tolerant plants for abiotic stresses
