Heat Tolerance — Tall Fescue

Festuca arundinacea Schreb.

Tall fescue possesses a high ability to adapt to extreme temperatures, maintaining photosynthetic activity and productivity due to its deep root system.

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

Assessment of heat tolerance in the crop is based on complex methods, including stress testing at temperatures around 40°C, analysis of antioxidant enzyme activity, and monitoring of the state of the photosynthetic apparatus. Under field conditions, the trait is evaluated by the retention of green leaf color, the absence of necrosis, and the ability to continue vegetation when other grasses reduce their growth rates.

The high heat tolerance of tall fescue ensures its productive longevity and stand stability during hot periods. Due to the development of a powerful root system, the crop effectively utilizes soil moisture from deep layers, which allows it to maintain its agronomic value and biomass under temperature stress, outperforming many other cool-season grasses in these indicators.
