由于各种生物活性化合物含量高，植物是生产有价值和有用的生物产品（如食品、化妆品、药品、生物刺激素、生物农药和饲料）的主要原料。不同的植物部分，例如：种子、果实、花、茎、叶和根都可以用于制造它们。如今，人们明显需要开发新的、高效的产品。和环境安全的方法刺激植物，生长和作物保护。植物提取物是一种新的、天然的、多化合物的产品，可以用于这些目的。它们具有抗真菌、抗菌、抗寄生虫、抗原虫、抗氧化、药用、芳香和抗炎的特性。这组天然产品有潜力成为适合可持续农业使用的新一代生物产品。本文综述了植物源性提取物/生物刺激素（PDBs）对受控、真实条件下以及各种非生物和生物胁迫下作物生长影响的文献综述；用于获得多氯联苯的提取方法，以及负责其生物刺激活性的特定成分。由于对人类和环境的毒性低等优点，这些生物产品的应用可能有利于可持续生产。增强了栽培植物对生物和非生物胁迫的抵抗力，提高了作物的产量和质量，减少了矿物肥料和杀虫剂的使用。然而，需要在工业和学术研究之间进行更深入的合作，以加速为未来农业开发新的环境安全解决方案。
Plants due to the high content of various bioactive compounds are the main raw material for production of valuable, and useful bio-products (e.g., food, cosmetics, medicines, biostimulants, biopesticides, and feed). Different plant parts, for instance: seeds, fruits, flowers, stems, leaves, and roots can be used for their manufacture. Nowadays, there is a clear need to develop new, efficient. and environmentally safe methods of stimulation of plant, growth and crop protection. Plant-based extracts are new, natural, and multi-compounds products that could be used for these purposes. They possess antifungal, antimicrobial, antiparasitic, antiprotozoal, antioxidant, medicinal, aromatic, and anti-inflammatory properties. This group of natural products has the potential to become a new generation of bio-products suitable for use in sustainable agriculture. The purpose of this review is to provide an overview of the literature describing the impact of plant-derived extracts/biostimulants (PDBs) on crops grown in controlled, and real conditions as well as under various abiotic and biotic stresses; the extraction methods used to obtain PDBs, and the specific constituents responsible for their biostimulating activity. The application of these bio-products could be beneficial for sustainable production, due to several advantages, such as low toxicity to humans and the environment. enhanced resistance of cultivated plants to biotic and abiotic stress, increased yields and quality of crops, as well as the reduction in the use of mineral fertilisers and pesticides. However, deeper cooperation between industrial and academic research is required to accelerate the development of new environmentally safe solutions for future agriculture.
