Variety traits
Waxy bloom is a layer of wax-like substances on the surface of plant organs that acts as a protective barrier against moisture evaporation, overheating, and pests. This trait is genetically determined and serves as an important criterion for a variety's resistance to abiotic and biotic stresses.
Mentioned in descriptions 5 256 varieties reference book.
Waxy bloom (epicuticular wax) is a layer of substances on the surface of leaves, stems, and fruits that acts as a transpiration barrier, reducing moisture loss during drought conditions and reflecting ultraviolet radiation for protection against overheating. Visually, it manifests as a characteristic glaucous sheen on the plant's surface.
The intensity of bloom formation is determined by the genetic characteristics of the variety, but is subject to environmental factors. Wax synthesis increases at lower temperatures (below 15 °C), higher levels of UV radiation, and moisture deficit, which allows the plant to adapt to changing growing conditions.
In the state variety testing system, this trait is assessed visually by experts on a scoring scale, where the degree of expression is determined by comparison with an accepted standard. The presence of a strong waxy bloom increases the crop's resistance to pest damage, but creates a hydrophobic surface that requires a specific approach to the selection of adjuvants when conducting treatments.
Selection based on the description text, not official resistance ratings: such data is not available in registers. Mention indicates that the trait is discussed in the variety's sources; see the variety's profile for details on what is specifically stated.
