Ychwanegu Tag | Crynodeb: | Free-living bacteria with various abilities related to plant growth and health have been termed plant growth promoting rhizobacteria (PGPR). PGPRs promote plant growth through various modes of action, either directly or indirectly. The benefits provided by these bacteria may include increased nutrient availability, phytohormone production, shoot and root development, protection against various phytopathogens, and disease reduction. In addition, PGPR can help plants resist abiotic stresses such as salinity, drought, and production of enzymes that detoxify plants of heavy metals. PGPRs have become an important strategy in sustainable agriculture, due to the possibility of reducing synthetic fertilizers and pesticides, promoting growth and plant health, and improving soil quality. There are many studies related to PGPR in the literature. However, the present work highlights the studies that used PGPR for the sustainable production of coffee cultivation in Ecuador. It was possible to identify that the most studied and widespread bacteria in the coffee rhizosphere are Rhizobium, Azotobacter, Azospirillum, Acetobacter and Pseudomonas. The performance of these strains depends on the characteristics of competition with natural microorganisms and according to the physicochemical and edaphic conditions of the soil. The use of PGPR allows to reduce the use of fertilizers such as phosphate, nitrogen and fungicides, trying to improve the absorption of nutrients. Greater knowledge of the bacterial characteristics that drive plant growth promotion could motivate and stimulate the development of creative solutions using PGPR in highly changing environmental and climatic settings. |
