Variety traits
Chrysanthemum indicum L.
The diameter of the capitulum (flower head) is a key morphological indicator of Chrysanthemum indicum, ranging from 1–2 cm in small-flowered forms to 15–17 cm in large-flowered cultivars.
In the reference 11 varieties crop Indian chrysanthemum, where this is mentioned in the description.
For Chrysanthemum indicum, measurements are taken on terminal inflorescences in their natural state. In accordance with international DUS protocols, observations for spray cultivars are conducted on unpinched plants, while for large-flowered cultivars, they are performed on specimens with lateral buds removed.
Inflorescence diameter is determined by varietal characteristics and agronomic practices. Bush formation techniques, such as pinching and disbudding, allow for the redistribution of nutrients to increase flower size. Photoperiodism also has a significant effect: when the photoperiod is shortened, the inflorescence diameter may decrease while becoming denser.
