Drought tolerance of Sedum

Sedum L.

A key biological trait of Sedum, driven by CAM photosynthesis, which allows the plant to minimize transpiration and maintain viability during prolonged moisture deficiency.

In the reference 13 varieties crop Ice Plant, where this is mentioned in the description.

The evaluation of drought tolerance in Sedum is based on the plant's response to restricted irrigation for 4–8 weeks. Key indicators include visual maintenance of decorative appearance, morphological parameters such as shoot growth and the root-to-shoot ratio, as well as physiological and biochemical markers: relative water content in tissues, levels of photosynthetic pigments, concentration of osmolytes, and oxidative stress markers.

High tolerance is characterized by the preservation of turgor and minimal accumulation of malondialdehyde under extreme conditions, which is most pronounced in species like Sedum lineare. This trait is closely linked to the crop's sensitivity to waterlogging; therefore, good drainage is critical for such plants, and the irrigation strategy must exclude constant moisture presence, which induces root rot and the loss of commercial quality.
