Cold tolerance of Anthurium andraeanum

Anthurium-Andreanum-Hybriden

Anthurium andraeanum is a thermophilic tropical epiphyte with no genetic adaptation to low temperatures. The crop possesses no varietal cold tolerance and is critically sensitive to exposure to temperatures below 15°C.

In the reference 5 varieties crop Anthurium, where this is mentioned in the description.

For Anthurium andraeanum, the optimal temperature range for development is 18–28°C. Temperatures below 15°C are considered unfavorable and cause a slowing of metabolism and growth rates. Exposure to temperatures below 7°C represents a critical threshold capable of causing irreversible tissue damage or plant death within a few days.

Cold stress in Anthurium andraeanum manifests as a loss of turgor, leaf chlorosis, and the emergence of necrotic spots, with temperatures near 5°C being extremely dangerous. The combination of low temperatures and high soil moisture triggers the development of root rots, while exposure to freezing temperatures leads to immediate crop death.
