The waxy bloom of onion is a key morphological trait providing protection against pathogens, regulation of transpiration, and resistance to the phytotoxic effects of herbicides.

where this is mentioned in the description.
In breeding practice, the intensity of the waxy bloom in onions is visually assessed during the active growing season on a scale that includes weak, medium, and strong degrees of expression. "Glossy" mutant forms, characterized by the near-total absence of a wax layer, are of particular interest for genetic research.
Functionally, the bloom creates a physical barrier to the penetration of pathogens into leaf tissues and reduces the rate of moisture evaporation. The presence of a pronounced wax layer is critical when applying chemical plant protection products, as it minimizes the risk of crop damage by herbicides during field treatments.
