Adaptation and Agricultural Significance of Syzygium cumini L. in Saline Environments: A Global Perspective on Jamun Cultivation and Salt Stress Resilience

Abstract

Syzygium cumini L., known commonly as jamun, is a fruit tree with significant adaptability to diverse environmental conditions, particularly saline soils. This review comprehensively explores the adaptation mechanisms of jamun to saline environments and its agricultural significance on a global scale. Given the increasing soil salinization worldwide, understanding the resilience of crops like jamun is crucial for sustainable agricultural practices in salt-affected regions. Jamun is native to the Indian subcontinent but has been cultivated in tropical and subtropical regions worldwide. Its ability to withstand various abiotic stresses, especially soil salinity, makes it an ideal candidate for cultivation in areas prone to such conditions. This review highlights the physiological and biochemical responses of jamun to high salinity, including ion regulation, osmotic adjustment, and antioxidant activity. These mechanisms help the plant maintain growth and productivity in environments where many other crops fail. Additionally, the review discusses the importance of jamun in traditional medicine and its nutritional benefits, emphasizing its potential for enhancing food security in saline-affected areas. The fruit's rich composition of vitamins, antioxidants, and minerals underscores its nutritional value, making it a beneficial addition to the diet in regions with limited crop diversity due to salinity. Furthermore, the paper addresses the agricultural practices conducive to maximizing jamun's yield in saline environments, including suitable propagation techniques and water management strategies. It also explores the genetic diversity within Syzygium cumini species, which could be leveraged to breed varieties with enhanced salt tolerance and better fruit quality. In conclusion, the global cultivation of jamun not only contributes to biodiversity but also offers a viable solution for agricultural productivity in salt-impacted soils. Continued research and development efforts are essential to optimize cultivation practices and expand the use of jamun in saline agriculture.
