Demonstrates enhanced seed germination and growth in crop plants using bacterial consortia, suggesting agricultural benefits.
The growth of vegetable plants is dependent on numerous environmental factors, including the presence of rhizosphere bacteria that produce phytohormones and support mineral uptake. The aim of this study was to determine the effect of symbiotic bacteria belonging to the Rhizobium leguminosarum species and other PGPR bacteria: Bacillus cereus, Chryseobacterium lathyri, and Lysinibacillus fusiformis, on seed germination and plant growth of a few crop species (i.e., white cabbage, broccoli, red pepper, and sugar beet). Three inoculation variants were tested: a mixture of R. leguminosarum strains (R), a mixture of other PGPR bacteria (B), and a combination of both of them (R + B). Biometric parameters such as seed germination, seedling growth, and the length and weight of upper parts and roots were determined. Our results showed diverse responses of the studied crop species to the bacterial mixtures used. In the case of variants R and R + B, the strongest effect of inoculation on seed germination and plant growth was observed. The obtained results indicated the agricultural potential of the analyzed bacterial consortia as biological support for the production of vegetable crops. They also emphasize the need for further research on their effectiveness in various environmental conditions.
