Method for evaluating cold endurance of anthurium andraeanum at flowering stage

Abstract

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.

Description

technical field [0001] The invention belongs to the field of plant cold resistance evaluation, and in particular relates to an evaluation method of anthurium anthurium cold resistance in flowering stage. Background technique [0002] Anthurium andraeanum is a plant of the genus Anthurium in the family Araceae. Because of its rich flower colors, unique flower posture, long flowering period and continuous seasons, it has become the second largest tropical flower in the international market after the tropical orchid. [0003] However, chilling damage will occur when the growth environment is lower than 12°C, which increases the heating cost greatly when planting anthurium in winter in my country, which has become an important factor restricting the development of anthurium industry. Therefore, cold-resistant anthurium varieties Performance evaluation is beneficial to hierarchical management and energy consumption reduction in the production process of Anthurium anthurium, and im...

AI Technical Summary

Problems solved by technology

[0008] The above evaluation methods mostly use detached leaves or anthurium seedlings, which are based on the evaluation of cold resistance under artificial low temperature stress environment, and there is a certain gap with the actual production conditions of anthurium, and they have not fully investigated the organs of anthurium. Therefore, there is a certain deviation in evaluating the cold resistance of Anthurium anthurium during the flowering period
