Chrysanthemum Inflorescence Diameter

Chrysanthemum L.

Inflorescence diameter is a key biometric indicator for chrysanthemum, which determines its varietal classification, ornamental quality, and market value of cut flowers.

In the reference 97 varieties crop Chrysanthemum, where this is mentioned in the description.

To measure the diameter of a chrysanthemum flower head, a ruler or a caliper with an accuracy of 0.5 cm is used. Based on this indicator, varieties are classified into small-flowered (up to 8–9 cm), medium-flowered (10–19 cm), and large-flowered (from 10–25 to 30 cm).

The realization of the genetic potential for inflorescence size depends on adherence to cultivation practices, temperature regimes above 18–20°C, nutrient intensity, and control of the photoperiodic response. An optimal day length (approximately 14.5 hours) during bud initiation is critical for the formation of a large receptacle.
