Sustainable soybean production and abiotic stress management in saline environments: a critical review

Abstract

Soybean (Glycine max L.) is an important oilseed crop around the world. Soybean growth, development and productivity are affected by changing environments that induce abiotic stresses. In soybean, salinity acts as a major abiotic stress that increases electrolyte leakage as well as Na + and proline content in plants, and adversely affects plant physiology. This review offers an understanding of how the growth, yield attributes, and yield of soybean decrease under salinity stress. To appreciate how soybean can better adapt to a changing climate that induces salinity stress, an understanding of the mechanisms underlying this stress is needed. Improved performance and yield in response to salinity stress can emerge from the application of novel strategies, such as the development of transgenic crops that enhance salt tolerance in soybean. Effective management strategies, including the use of compatible antioxidants such as proline or glycinebetaine, coupled with a more effective balance of nutrients or the use of organic fertilizers, allow salinity to be mitigated, thereby improving yield and other growth-related quality parameters in soybean.

Exogenous Sodium Nitroprusside Mitigates Salt Stress in Lentil (Lens culinaris Medik.) by Affecting the Growth, Yield, and Biochemical Properties

“…Under salinity, plants become less dynamic to draw nutrients from the soil and, resultantly, exhibit nutrients deficiency symptoms [ 8 ]. If this situation remains unaddressed in the long run, a reduced photosynthetic rate, chlorosis, and necrosis [ 9 ] eventually reduce the yield traits, grain yield, and quality [ 10 , 11 , 12 ]. In such circumstances, the plant life cycle depends upon its antioxidant ability to detoxify the ROS.…”

Engineering Multiple Abiotic Stress Tolerance in Canola, Brassica napus

“…Relative water content (RWC) is a physiological measure of cellular hydration in the plants. Up to 48% of RWC loss in B. napus leaves been reported under drought conditions (Sabagh et al, 2019). However, drought is not the only abiotic stress that leads to cellular dehydration as it is also induced under salt stress, which causes a state of toxicity and osmotic stress (Zhang X. et al, 2014;Rezayian et al, 2018).…”

Salinity Stress in Maize: Effects of Stress and Recent Developments of Tolerance for Improvement

“…The detrimental impacts of salt stress manifest through a reduction in the relative water potential of plants which causes decline in plants growth [7], coupled to a negative effect in soil and water quality both in the short and long term [8,9]. Salt stress is associated with the moisture stress that decreases plant growth and ultimately reduces plant yield even at soil moisture contents that are not limiting for crop productivity (Figure 1) [10,11].…”
