Zantedeschia inflorescence

Zantedeschia Spreng.

The Zantedeschia inflorescence consists of a spadix surrounded by a modified leaf called a spathe. This is a key morphological trait subject to standardized assessment during variety testing according to UPOV guidelines.

In the reference 146 varieties crop Arum-lily, where this is mentioned in the description.

The Zantedeschia inflorescence consists of a spadix and the surrounding spathe, which is often mistakenly taken for a flower. According to variety testing protocols, inflorescence parameters, including shape, size, and color, are assessed at the onset of anther dehiscence, with subsequent observations of color changes conducted 2–3 weeks later.

Inflorescence traits are definitive for the commercial value of the crop and its market classification. Early harvesting before the full development of the inflorescence is considered a technological defect, as it prevents the proper opening of the flowers. Gibberellins are used in agronomic practice to stimulate inflorescence development.
