Abstract
- The production of horticulture crops is severely restricted by abiotic stress factors such as salinity, drought, temperature fluctuation (low and high), and heavy metals (HMs). Abiotic stress causes metabolic changes in horticultural plants that impair growth and productivity. In this era of global climate change, extreme environmental conditions reinforce the situation and severely limit plant growth and productivity. Researchers have been investigating for a long time to determine how resilience and response to environmental stress elements. The use of phytohormones to mitigate the adverse effects of abiotic stresses on horticultural plants has been widely acknowledged as a powerful strategy. Salicylic acid (SA) has been extensively studied for its importance in improving plant abiotic stress tolerance. However, the processes that may underlie SA-induced plant tolerance to significant abiotic stressors are still poorly understood. Based on recent reports, this paper provides an overview of the role of SA in horticultural plants under both optimal and stressful conditions; critically evaluates the role of SA in plants exposed to key abiotic stresses; discusses potential mechanisms potentially governing SA-induced plant abiotic stress-tolerance; and briefly highlights significant aspects that have yet to be explored in the current context. [Display omitted] • Abiotic stresses significantly hindered plant growth and development. • Salicylic acid is a phenolic molecule that regulates plant growth and development. • Salicylic acid efficiently protected leaf photosynthetic efficiency under stress environment. • Salicylic acid reduced oxidative damage and increased antioxidant enzymes activity.
