Variety traits

Dahlia Lodging

Dahlia Cav.

Dahlia lodging is the leaning or falling over of plant stems due to wind, rain, or the inability of the stem to support the weight of large inflorescences.

In the reference 62 varieties crop Dahlia, where this is mentioned in the description.

In dahlias, this trait is a varietal characteristic, most typical of tall-growing cultivars with large inflorescences. Lodging is determined by stem strength and an imbalance between stem height and the total mass of the flower head, which distinguishes this phenomenon from the morphological factors that cause lodging in cereal crops.

In dahlia cultivation, lodging is considered a critical factor that reduces aesthetic value and marketability, shortens the flowering period, and contributes to mechanical stem damage. Qualitative characteristics are used to assess varietal resistance, as standardized quantitative scales for this crop do not exist. It is important to distinguish between mechanical stem lodging and seedling lodging caused by pathogens such as Fusarium oxysporum, which infect the root system and root collar.
