Hosta cold hardiness

Hosta Tratt.

The cold hardiness of Hosta is determined by the ability of plant tissues to withstand damage when exposed to low temperatures, which is expressed through the lethal temperature index LT50.

In the reference 11 varieties crop Hosta, where this is mentioned in the description.

Assessment of Hosta cold hardiness is conducted by determining the critical LT50 temperature at which 50% of plant tissues die. The primary research methods include the electrolyte leakage method, which allows for the evaluation of cell membrane damage, visual assessment of necrosis, and analysis of reducing sugar content in tissues as biochemical markers of resistance.

Specific LT50 values vary depending on the plant species; for example, values of approximately -11.14 °C have been recorded for Hosta plantaginea. These indicators are used to assess crop survival during recurrent spring frosts in the vegetative phase and to determine overall winter hardiness in regional conditions.
