The invention discloses a method for evaluating the cold endurance of anthurium andraeanum at the flowering stage. In the method, in a natural low-temperature environment, natural environment low-temperature stress is conducted on the variety of anthurium andraeanum at the flowering stage, the cold damage indexes of leaf stalks, leaves, flower stalks and bracts are counted according to the morphologic expression of cold damage of the variety of anthurium andraeanum to be evaluated, on the basis, a main component integrate scoring formula is established, through the formula, a cold endurance integrated score is calculated, and the cold endurance of the variety is evaluated in combination with clustering analysis. Based on the winter natural low-temperature environment, evaluation is conducted, the winter natural low-temperature environment is close to the growth environment of anthurium andraeanum, and a complex evaluating reagent is not needed; in the method, the expression of the colddamage of the leaf stalks, the leaves, the flower stalks, the bracts and other organs is involved, investigation is comprehensive, operation is easy, costs are low, and evaluating results are stableand favorable to guidance for breeding and large-scale production of the low-temperature-resistant variety of anthurium andraeanum.
