Waxy bloom — leek

Allium porrum L.

A morphological trait of leek characterized by the intensity of the glaucous hue of the leaves, evaluated on a five-point scale during variety trials.

In the reference 32 varieties crop Leek, where this is mentioned in the description.

The intensity of the waxy bloom in leek is determined visually and classified on a scale from 1 (absent or very weak) to 7 (very strong). This trait is a varietal characteristic: low values correspond to a bright green leaf color, whereas high values give the plant a pronounced glaucous hue.

Biologically, the waxy layer serves as a hydrophobic barrier that increases the leek's resistance to moisture loss and the impact of pests, such as thrips. In agronomic practice, it is important to distinguish this natural varietal trait from pathological coatings that occur during fungal infections.

The presence of a strong waxy bloom affects technological processes by hindering the wetting of the leaf surface during spraying. To ensure the efficacy of pesticides when working with varieties that possess a pronounced bloom, the inclusion of adjuvants in tank mixtures is mandatory.
