Abstract

Plants are continuously exposed to various stresses that can prevent them from reaching their full genetic potential. This makes them a key point of study for plant scientists seeking to understand how these stresses influence their metabolism and responses, and how these stresses can put their productivity and food safety at risk. Studies that aim to provide improvements in salinity tolerance for crops using a variety of measures still have a vast amount of open knowledge. Furthermore, new agronomic alternatives have shown efficacy in promoting and sensitizing plant defense mechanisms when exposed to different environmental stresses. However, in order to study these new measures, it is necessary to understand how these high concentrations can affect the plant directly or indirectly, influencing germination, growth, and production. Once the plants present different responses to the salt level, they may present sensitivity or resistance to this factor in the environment. This is because they may present adaptation mechanisms to this condition and maintain survival and productive potential, or even achieve better results. Thus, there is much to be studied to understand the dynamics of salt stress in plants and the metabolic, physiological and morphological responses triggered by salt stress.
