Salt-tolerance and Soil Improvement Mechanism of Suaeda salsa: Research Progress

doi:10.11924/j.issn.1000-6850.casb20191200947

Abstract

Abstract:

As one of the pioneer plant in salt soil, Suaeda salsa can survive in soil with 3% salt content, which is an important germplasm resource, and has a crucial application potential in the research of plant resistance mechanism, development and utilization of salt-tolerant genes and soil ecological remediation. To fully understand the salt tolerance mechanism of Suaeda salsa and its mechanism of soil improvement, from the aspects of morphology, physiology and biochemistry and molecular level, we summarize its salt tolerance mechanism, discuss its effect on salt alkaline soil physical and chemical properties, microbial species and refinement of soil nutrients, and review the research on its role in controlling soil heavy metals and organic pollutants. Based on the study, we argue that more attention should be paid to the key salt tolerance gene of Suaeda salsa, its role in plant community succession process, and the combined mechanism of Suaeda salsa and microbial species on soil improvement.

Key words: Suaeda salsa, salt stress, salt-tolerant mechanism, mechanism of soil improvement
