Priming techniques for sustainable Agro-Ecological system and abiotic stress mollification: A Review
Journal Title: Environment Conservation Journal - Year 2024, Vol 25, Issue 3
Abstract
Abiotic stress refers to the diverse range of environmental challenges that plants encounter. Environmental stressors such as salt, temperature, nutritional deprivation, and heavy metal toxicity can lead to problems in the functioning of seedling adaption systems. Furthermore, they can hinder the formation of plumules and radicles in seedlings, as well as their subsequent development and growth, both of which can lead to reduced crop production. Soil salinity poses a significant challenge to global food supply since salt stress dominates as a primary determinant constraining agricultural productivity. By the year 2050, it is projected that drought stress will result in a 50% reduction in global productivity. Multiple methodologies, including biotechnological approaches, conventional breeding methods, conservative breeding, agronomical approaches, and priming techniques, have shown effectiveness in reducing the negative impacts of abiotic stress and adapting to its severe conditions. The use of seed priming treatments regulates the production of antioxidants and promotes the accumulation of osmolytes to mitigate the negative consequences of various abiotic stress responses. When subjected to abiotic stress, crop plants cultivated from primed seeds respond rapidly at the cellular level. The major emphasis of this review is on the impact of abiotic stress on plant physiology and productivity, strategies for its management, and possible solutions. Furthermore, it explores several methods of priming, namely bio priming with PGPR, a biological technique that entails the introduction of bacteria.
