Abstract：
The application of biostimulants has been proven to be an advantageous tool and an appropriate form of management towards the effective use of natural resources, food security, and the beneficial effects on plant growth and yield. Plant-growth-promoting rhizobacteria (PGPR) are microbes connected with plant roots that can increase plant growth by different methods such as producing plant hormones and molecules to improve plant growth or providing increased mineral nutrition. They can colonize all ecological niches of roots to all stages of crop development, and they can affect plant growth and development directly by modulating plant hormone levels and enhancing nutrient acquisition such as of potassium, phosphorus, nitrogen, and essential minerals, or indirectly via reducing the inhibitory impacts of different pathogens in the forms of biocontrol parameters. Many plant-associated species such as Pseudomonas, Acinetobacter, Streptomyces, Serratia, Arthrobacter, and Rhodococcus can increase plant growth by improving plant disease resistance, synthesizing growth-stimulating plant hormones, and suppressing pathogenic microorganisms. The application of biostimulants is both an environmentally friendly practice and a promising method that can enhance the sustainability of horticultural and agricultural production systems as well as promote the quantity and quality of foods. They can also reduce the global dependence on hazardous agricultural chemicals. Science Direct, Google Scholar, Springer Link, CAB Direct, Scopus, Springer Link, Taylor and Francis, Web of Science, and Wiley Online Library were checked, and the search was conducted on all manuscript sections in accordance with the terms Acinetobacter, Arthrobacter, Enterobacter, Ochrobactrum, Pseudomonas, Rhodococcus, Serratia, Streptomyces, Biostimulants, Plant growth promoting rhizobactera, and Stenotrophomonas. The aim of this manuscript is to survey the effects of plant-growth-promoting rhizobacteria by presenting case studies and successful paradigms in various agricultural and horticultural crops.
摘要：
生物兴奋剂的应用已被证明是有效利用自然资源的有利工具和适当的管理形式，粮食安全,以及对植物生长和产量的有益影响。促进植物生长的根际细菌（PGPR）是与植物根相连的微生物，可以通过不同的方法来增加植物生长，例如产生植物激素和分子以改善植物生长或提供增加的矿物质营养。它们可以在作物发育的所有阶段定植根的所有生态位，它们可以通过调节植物激素水平和增强钾等养分的获取直接影响植物的生长和发育，磷，氮，和必需的矿物质，或间接通过以生物控制参数的形式降低不同病原体的抑制作用。许多植物相关物种，如假单胞菌，不动杆菌,链霉菌,Serratia,节杆菌,红球菌可以通过提高植物抗病性来促进植物生长，合成刺激生长的植物激素，抑制病原微生物。生物刺激剂的应用既是一种环境友好的做法，也是一种有前途的方法，可以增强园艺和农业生产系统的可持续性，并提高食品的数量和质量。它们还可以减少全球对危险农业化学品的依赖。科学直接，谷歌学者，SpringerLink,CABDirect,Scopus,SpringerLink,泰勒和弗朗西斯,WebofScience,并检查了Wiley在线图书馆,并根据术语“不动杆菌”对所有手稿部分进行搜索，节杆菌,肠杆菌,苍白杆菌,假单胞菌,红球菌,Serratia,链霉菌,生物兴奋剂,促进植物生长的根瘤菌，和窄食单胞菌。本手稿的目的是通过在各种农业和园艺作物中提供案例研究和成功范例来调查促进植物生长的根瘤菌的作用。
