Morphophysiological, Enzymatic, and Elemental Activity in Greenhouse Tomato Saladette Seedlings from the Effect of Plant Growth-Promoting Rhizobacteria

The tomato is a widely cultivated and consumed vegetable globally. Comarca Lagunera an important tomato-exporting region of Mexico. Salinity abiotic factor that reduces productivity increases production costs. To advance growing period, there high demand for the sustainable seedlings. Plant-growth-promoting rhizobacteria (PGPR) are characterized by improving plant growth through different mechanisms can be option reducing misuse chemical fertilizers. importance application strains, evaluating various inoculation methods (in seed, soil, foliar spraying, root immersion), should evaluated to propose biofertilization packages in specific crop. Thus, study aimed determine effect PGPR (Bacillus paralicheniformis, Acinetobacter guillouiae, Aeromonas caviae, Pseudomonas lini) vs. nutrient solution distilled water seedlings stage saladette-type on morphophysiological variables, nitrate reductase (NR) enzyme activity, minerals via tissue analysis under greenhouse conditions. four were inoculated (inoculation sprinkling, both) conditions vivo 40 days after sowing such as seedling height; stem diameter; displaced volume; fresh dry weight matter leaves, stems, roots; leaf area; activity. showed significant results lini control, with 40% higher values, average, height, diameter, volume, root, leaf, stem. response enzymatic mineral content was variable water. Studies related promotion plants subsequent phenological stages tomato, considering selected PGPR, considered future research.
