Drought tolerance — Echinacea purpurea
Echinacea purpurea (L.) Moench
Echinacea purpurea exhibits drought tolerance once established, adapting to moisture deficit by altering the root-to-shoot biomass ratio. Under arid conditions, crop productivity declines, necessitating the management of irrigation intervals to maintain commercial yield.
In the reference 14 varieties crop Purple coneflower, where this is mentioned in the description.
For Echinacea purpurea, drought tolerance is an age-related trait: during the first year of vegetation, especially during the rosette formation stage, the crop is critically dependent on regular irrigation. Under moisture deficit, plants exhibit an adaptive response by altering the ratio of root mass to above-ground organs to optimize water uptake.
The evaluation of the species' drought tolerance is based on the comparison of morphometric parameters, such as plant height, inflorescence diameter, and leaf count, as well as physiological indicators, including the freshness index and survival rate at various irrigation intervals. It has been experimentally established that increasing the intervals between irrigation to 7–30 days leads to a significant decrease in the yield of air-dry mass, whereas optimal productivity is achieved with an irrigation interval of 3 days.
