Seaweeds are macroscopic, multicellular marine algae. Their commercial
extracts have recently become popular as plant biostimulants, which may
also impart tolerance to treated plants against abiotic stresses. Seaweed
extracts have been reported to enhance root growth, plant health and
biomass under various stress conditions, such as salinity, temperature
stress and hypoxia. However, the mechanism(s) responsible for these varied
responses remain unclear. Here we briefly review the plant abiotic stress
alleviating effects of seaweed extracts and the potential role of chemical
constituents of seaweeds in those extracts in such effects.
