Dahlia double-flowering

Dahlia Cav.

Biologically, the double-flowering of dahlias is the process of transformation of tubular florets of the central disc into ray florets. This qualitative trait serves as the main criterion for the classification of varieties into groups according to international standards.

In the reference 133 varieties crop Dahlia, where this is mentioned in the description.

The degree of double-flowering in dahlias is determined by the ratio of ray florets to tubular florets in the inflorescence. This trait is used in agronomy and breeding to categorize varieties into specific types, such as single, anemone-flowered, semi-double, or double, and is recorded as a qualitative characteristic during variety testing.

The double-flowering trait is variety-specific, although its expression can vary depending on environmental conditions. During cultivation or seed propagation, inflorescences may lose their fullness and acquire a simpler form, which affects the ornamental properties of the plant.

General information about the subject — on the page Double flowering / Reversion.
