The application of biostimulants from natural origin represents one of the most innovative and promising strategies to promote plant growth and improve crop productivity. The biostimulants have the potential to release dormancy and enhance seed germination of many plant species by altering the physiological processes in seeds even under abiotic stress. The seed application of biostimulants has been considered as a simple, beneficial and sustainable technique to enhance crop productivity. An understanding of non-microbial biostimulants-induced seed germination, dormancy release and seedling establishment mechanisms may help to improve crop productivity. However, the impending mechanisms involved in the regulation of seed germination and seedling establishment by non-microbial biostimulants are still elusive. In this review, the possible mode of action of various non-microbial biostimulants in seed germination and the seedling establishment under optimal and sub-optimal conditions has been discussed. Furthermore, the gaps in utilizing the full potential of these biostimulants are also addressed.
