The waxy bloom of white cabbage is a morphological trait that determines the hydrophobicity of the leaf surface. Its expression is evaluated visually in breeding programs according to an intensity scale and directly affects the efficacy of foliar treatments.

where this is mentioned in the description.
In white cabbage variety testing and breeding, the intensity of the waxy bloom is classified on a qualitative scale as weak, medium, or strong. This characteristic is a varietal trait and does not have standardized quantitative measurement methods within the state variety testing system.
A high degree of wax layer development creates a pronounced hydrophobic effect, which causes spray solutions to roll off the leaves. To ensure treatment efficacy when working with such varieties, the mandatory use of surfactants (adjuvants) is required. The intensity of this layer's formation also depends on the sulfur supply to plants during the growing season and influences transpiration rates.
