Abstract
Evapotranspiration of Sedum is influenced by CAM induction, which is different between plant species. We measured the index of CAM induction and evapotranspiration in Sedum album, Sedum kamtschaticum, Sedum reflexum by non-destructive measurement to elucidate the relevance between physiological characteristics and changes in thermal environment. Evapotranspiration for a long period has decreased with CAM induction. Evapotranspiration for a short period has increased with the increasing of leaves weight ratio and we suggest that this may lead to the increasing of water retention. We concluded that gross evapotranspiration are dependent on both the index of CAM induction and leaves weight ratio.
