Gladiolus flower color

Gladiolus L.

Gladiolus flower color is a key classification trait described by the international NAGC numerical coding system, where the second digit defines the color group and the third indicates tone saturation.

In the reference 53 varieties crop Gladiolus, where this is mentioned in the description.

To systematize coloration, a three-digit code is used, where the tens represent the base color from white to brown, and the units represent the degree of saturation from pale to dark shades. The presence of an odd digit at the end of the code indicates additional decorative elements, such as throat blotches, picotee edges, or stippling, the forms of which are described in detail during breeding assessment.

The color trait correlates with the biological characteristics of the cultivar, particularly with the vegetative propagation coefficient. Cultivars with blue coloration often show reduced activity in forming replacement corms, whereas pink-magenta and orange-salmon forms show higher rates. Furthermore, the coloration is linked to the biochemical composition of flower tissues, specifically to their acidity levels.
