Stevia rebaudiana is an important medicinal plant which represents the most important sugar substitute in many countries. Poor seed germination of this plant is a critical problem that affects the final yield and the availability of the products in the market. Continuous cropping without supplying soil nutrients is also a serious issue as it results in declining soil fertility. This review highlights the important use of beneficial bacteria for the enhancement of Stevia rebaudiana growth and its dynamic interactions in the phyllosphere, rhizosphere, and endosphere. Fertilizers can increase crop yield and preserve and improve soil fertility. There is a rising concern that prolonged usage of chemical fertilizers may have negative impacts on the ecosystem of the soil. On the other hand, soil health and fertility are improved by plant growth-promoting bacteria which could eventually increase plant growth and productivity. Accordingly, a biocompatible strategy involving beneficial microorganisms inoculation is applied to boost plant growth and reduce the negative effects of chemical fertilizers. Plants benefit extensively from endophytic bacteria, which promote growth and induce resistance to pathogens and stresses. Additionally, several plant growth-promoting bacteria are able to produce amino acids, polyamines, and hormones that can be used as alternatives to chemicals. Therefore, understanding the dynamic interactions between bacteria and Stevia can help make the favorable bacterial bio-formulations, use them more effectively, and apply them to Stevia to improve yield and quality.
甜菊是一种重要的药用植物，是许多国家最重要的糖替代品。这种植物种子发芽率低是一个关键问题，会影响最终产量和市场产品的供应。连续种植而不供应土壤养分也是一个严重的问题，因为它会导致土壤肥力下降。本综述强调了有益细菌在提高甜菊生长及其在叶围、根围和内围的动态相互作用中的重要作用。肥料可以提高作物产量，保持和改善土壤肥力。人们越来越担心，长期使用化肥可能会对土壤生态系统产生负面影响。另一方面，植物促生细菌可以改善土壤健康和肥力，最终可以提高植物的生长和生产力。因此，应用生物相容性策略，即接种有益微生物，可以促进植物生长，减少化肥的负面影响。内生细菌可以促进植物生长，并诱导植物对病原体和胁迫的抗性，植物从中广泛受益。此外，一些植物促生细菌能够产生氨基酸、多胺和激素，可以作为化学品的替代品。因此，了解细菌与甜菊之间的动态相互作用有助于形成有利的细菌生物制剂，更有效地利用它们，并将其应用于甜菊，以提高产量和质量。
