پیامدهای تغییر اقلیم برگیاه دارویی سیاه دانه ( Nigella sativa)

Climate change is a phenomenon that is happening in most regions of the world as well as in our country, Iran. The present study was conducted in a review form with the aim of investigating the consequences of climate change on the black seed medicinal plant. One of the effective factors in climate change is the increase of greenhouse gases, temperature increase and precipitation fluctuations, which can affect the performance of crops and overall production in this sector. Knowing the effects of climate change on medicinal plants as well as the effects it can have on product performance and yield is of significant importance. Among the factors of adaptation to this phenomenon, which can play an important role, we can refer to the type of product and the pattern of cultivation and production or the creation of cultivars tolerant to environmental stresses (drought, salinity, heat). Black seed medicinal plant is one of the valuable plants which, in addition to being a vehicle, is cultivated in different parts of Iran due to its many uses in various pharmaceutical, food and cosmetic industries. Limiting factors, including climate change, can have an adverse effect on the growth, production and quality of active ingredients in black seed medicinal plant. The genotype of the plant plays a key role in these changes, and the selection of drought-resistant species and genotypes will increase the yield and percentage of effective substances and will bring higher economic performance.
