Advanced Tips Plant Growth-Promoting Rhizobacteria in Soilless Cultivation
Plant growth-promoting rhizobacteria (PGPR) are beneficial bacteria that colonize the root zone, acting as biostimulants, biofertilizers and biocontrol agents that influence plant responses to their environment.Rhizobacteria inhabit the rhizosphere—the region of soil immediately surrounding roots, as well as the sticky root surfaces themselves. This zone regulates key factors such as nutrient availability and microbial interactions that support plant health and survival.Although soilless systems lack a traditional rhizosphere, root surfaces remain bioactive, allowing PGPR to colonize them in hydroponic conditions. This …
