Abstract
Under long days, onions form spherical bulbs and accumulate nutrients such as fructose-based oligosaccharides (FOS) in their bulbs. 1-Kestose and nystose, inulin-type FOS, have been identified as endogenous stimulants of bulb formation. According to the structure-activity-relationship study, the inulobiose moiety in 1-kestose is required for the bulb formation. Inulin-type FOS is well known as a prebiotic, which is beneficial to people’s health, and does not show toxicity. FOS has not been linked to any negative crop growth effects. Thus, it could be a potential eco-friendly growth promoter.
