Results and Discussion
Plant growth–promoting rhizobacteria, most of which are Pseudomonas and Bacillus species,
are applied to a wide range of agricultural crops to enhance growth by promoting seedling
emergence, plant biomass, and/or disease control [21]. In this study one of these beneficial
species, B. subtilis FZB24®
, was tested for its effect on the growth and quality of saffron
composition.
