“…Солевой стресс вызывает подавление роста и активности фотосинтеза, а также изменение проводимости устьиц, их количества и размера у растений фасоли. Он снижает транспирацию и водный потенциал клеток у растений фасоли, подверженных воздействию соли [24]. Известно, что высокий уровень засоления почвы и поливной воды влияет на многие физиологические и метаболические процессы, приводя к снижению роста клеток.…”

Impacts of climate change on vegetable production and ways to overcome them

Vegetables play a key role in food security and nutrition as the food system shifts from food quantity to dietary quality and health benefits. One of the main reasons for the low production and declining average yields of most vegetable crops is climate change. Important limiting factors in maintaining and increasing vegetable crop yields are rising temperatures, reduced water availability for irrigation, flooding and salinity. Under changing climatic conditions, crop failures, declining quality and increasing pest and disease problems are becoming commonplace and making vegetable production unprofitable. Since many physiological processes and enzyme activity are temperature dependent, they will be greatly affected. Drought and salinity are two important effects of rising temperatures that reduce vegetable crop yields. These impacts of climate change also affect the emergence of pests and diseases, host-pathogen interactions, distribution and ecology of insects, timing of emergence, migration to new locations, and their ability to overwinter, all of which become a major barrier to vegetable production. To mitigate the adverse effects of climate change on the productivity and quality of vegetable crops, sound adaptation strategies need to be developed. Emphasis should be placed on the development of production systems that improve water efficiency and are adapted to hot and dry conditions. Technological practices, such as mulching with crop residues and plastic materials, help maintain soil moisture. Excessive soil moisture due to heavy rains becomes a serious problem that can be solved by growing crops in raised beds. An effective way to solve these problems is to create genotypes that are resistant to high temperatures, moisture, salinity and resistance to climatic conditions, using traditional and non-traditional breeding methods, genomics, biotechnology, etc.

“…Growth of legumes is generally affected by several abiotic stresses causing as a response changes in the plant phenotype (Araújo et al, 2015). Among the reported changes in common beans due to abiotic stresses are less leaf expansion due to ultraviolet‐B radiation (Riquelme et al, 2007), increase of production of malondialdehyde, antioxidants and carotenoids, a decrease in the chlorophyll content of leaves due to heavy metal exposure (Zengin, 2013), reduction of seedling emergence after low temperature treatment (De Ron et al, 2016), as well as suppression of growth, photosynthesis and transpiration under high soil salinity (Kaymakanova et al, 2008). Changes in protein expression, reduced germination, stunted growth, serious damage to photosynthesis and a reduction in nutrient uptake particularly occur after exposure to drought/heat stress, (Mathobo et al, 2017; Nadeem et al, 2019; Zadražnik et al, 2013).…”

“…exhibiting a reduction in plant growth overall, as well as in the growth of roots and shoots and leaf area [15]. reduced levels of chlorophyll, delayed flowering, and decreased enzyme activity [16,17], as well as nutritional deficiencies such as N, P, K, Ca, and Mg deficiency in plants [18]. In many plants, salt stress also leads to the accumulation of toxic active oxygen species in the cells, which can later result in injury to proteins, membrane lipids, and nucleic acids [19,20].…”

In the world, salinity has become an increasing danger for agricultural production. A factorial pot experiment using a completely randomized design (CRD) was conducted in the present research, aimed to look at how growth, yield parameters, and biochemical contents were influenced by the exogenous application of calcium chloride (CaCl2, 0, 5, and 10 mM) of tomato exposed to salt stress (NaCl, 0, 25, and 75 mM), Growth was slowed and Both the sodium percentage and proline content increased under salt stress. However, the growth, yield, and biochemical content characteristics were improved by the application of Ca, enhanced plant height, dry weight of the shoots and roots, the number of fruits per plant, fruit weight, the percentage of nitrogen, calcium, magnesium, phosphorus, potassium, relative water content (RWC), and increased proline content, moreover a significant reduction in the sodium percentages, when compared to the control. Lastly, exogenous Ca use improves resistance to salt stress. Moreover, the use of 10 mM CaCl2 caused the beneficial effects of Ca, which has been suggested to enhance tomato performance in salinized conditions.
