Heavy metal contamination poses a significant barrier to oilseed crop cultivation, leading to reduced growth and yield losses, as well as potential food safety concerns. Biostimulants have garnered interest as a long-term strategy for enhancing plant tolerance to heavy metal stress through physiological, biochemical, and molecular pathways. This chapter examines numerous forms of biostimulants, such as humic compounds, protein hydrolysates, seaweed extracts, and microbial inoculants, emphasizing their function in enhancing nutrient absorption, activating antioxidant defense mechanisms, and lowering metal toxicity of oilseed crops. Using biostimulants improves crop resilience while promoting soil health and sustainable agriculture practices. While their potential is great, further study is needed to optimize application tactics and better understand how they interact with plant metabolism under heavy metal stress.

摘要

Heavy metal contamination poses a significant barrier to oilseed crop cultivation, leading to reduced growth and yield losses, as well as potential food safety concerns. Biostimulants have garnered interest as a long-term strategy for enhancing plant tolerance to heavy metal stress through physiological, biochemical, and molecular pathways. This chapter examines numerous forms of biostimulants, such as humic compounds, protein hydrolysates, seaweed extracts, and microbial inoculants, emphasizing their function in enhancing nutrient absorption, activating antioxidant defense mechanisms, and lowering metal toxicity of oilseed crops. Using biostimulants improves crop resilience while promoting soil health and sustainable agriculture practices. While their potential is great, further study is needed to optimize application tactics and better understand how they interact with plant metabolism under heavy metal stress.
