The environmental and health risks associated with the application of synthetic chemical inputs in agriculture increased the demand for technologies that allow higher performance and quality of vegetable crops by implementing synergistic materials with the principles of sustainability. In this work, the seed coating with the biomass of Dunaliella salina incorporated in a bioplastic film of Manihot esculenta (cassava) was evaluated as an initial growth and secondary compounds stimulator of Coriandrum sativum (coriander) plants. The obtained results demonstrated that the coating stimulated an increase in the germination percentage (28.75%) and also in concentration of bioactive compounds, such as the six-fold increment of caffeic acid (13.33 mg 100 g-1). The carbohydrates, lipids, and proteins present in the microalgae biomass seem to be responsible for these increments once they are known for providing energy to the seedling development and coordinating the secondary metabolites synthesis. As conclusion, we consider the coating with biomass of D. salina an alternative for crop improvement that contributes to the development of sustainable agricultural practices.
与农业中合成化学投入物的应用相关的环境和健康风险，增加了对技术的需求，这些技术通过与可持续性原则协同的材料来实现蔬菜作物更高的性能和质量。在这项工作中，评估了将杜氏盐藻生物质纳入木薯（木薯）生物塑料薄膜中的种子包衣，作为芫荽（芫荽）植物初始生长和次生化合物的刺激物。所得结果表明，包衣刺激了发芽率（28.75%）的增加，并且还刺激了生物活性化合物的浓度增加，例如咖啡酸增加了六倍（13.33mg 100g-1）。微藻生物质中存在的碳水化合物、脂质和蛋白质似乎是这些增加的原因，因为它们已知为幼苗发育提供能量并协调次生代谢物的合成。总之，我们认为杜氏盐藻生物质的包衣是一种作物改良的替代方法，有助于可持续农业实践的发展。
