Abstract: The plant biostimulants are diverse substances or microorganisms which include humic acid, chitin and its derivatives, seaweed extracts, etc. applied to enhance plant growth, development, tolerance to abiotic stresses and crop quality traits regardless of its nutrient content. The emergence of biostimulants has provided new ideas and solutions for the safety of agricultural products, and they have been widely used in agricultural production. They also have become a powerful tool for improving the efficiency of fertilizers and pesticides. The purpose of this review is to better under-standing of the concept of plant biostimulants including main categories and regulatory mechanisms in plants. Moreover, the characteristics of these biostimulants and its effects on plant growth, development, tolerance to abiotic stress, plant nutrition and crop quality traits are thoroughly described. In addition, this paper also briefly described the application prospects of plant biostimulants in agricultural production, opportunities and future challenges.

Key words: biostimulants, plant immunity, seaweed extracts, chitosan and derivative, microbial inoculants
