Zusammenfassung: | The invention discloses a method for quickly determining the heat resistance of winter wheat. The method comprises the following steps that a variety to be determined and a heat-resistance control variety are planted, and a temperature recorder is arranged at the position with a certain distance from the ground to monitor the environment temperature; after 80% or more of wheat blooms and embryos are mature, the variety to be determined and the heat-resistance control variety are subjected to heat stress treatment and normal treatment, wherein the heat stress treatment is carried out by controlling the temperature in a shed to be higher than the temperature of the outside of the shed, and the normal treatment is to control the temperature in the shed and the temperature of the outside of the shed to be consistent; and canopy temperatures of the variety to be determined and the heat-resistance control variety are measured by a thermal imager located above the canopy of the wheat, or thechlorophyll content of th |
