Embodiment Construction

[0034] The establishment of the chrysanthemum waterlogging tolerance evaluation system provided by the present invention and the waterlogging tolerance appraisal method, its embodiment is as follows:

[0035] 1. Establishment of a grading and scoring evaluation system for waterlogging tolerance

[0036] Potted plant flooding identification method was used: flooding 2 cm above the soil surface, continuous flooding treatment for 6 days, and four indicators were selected for evaluation: leaf shape, leaf color, stem color and shape at the flooded place. Firstly, the grading range of each index was determined, and then the total score was calculated according to the grade scoring standard, and then the waterlogging tolerance of chrysanthemum was comprehensively evaluated by referring to the evaluation plan.

[0037] (1) Determination of morphological waterlogging damage index

[0038] The chrysanthemum morphological waterlogging damage index is determined as 7 grades, referring to...

Abstract

The invention relates to an evaluation identification method for chrysanthemum flooding tolerance, belonging to the plant cultivation and breeding technical field, which comprises: according to the figure change of a chrysanthemum in blood, dividing the figure flood injury index into 7 levels, using four appearance figure indexes as leaf color, leaf figure, stem color and stem figure to quantitatively and classify the figure flood injury indexes, establishing a level score standard and an evaluation scheme, using the sum of the index scores to comprehensively evaluate the flooding tolerance, establishing an evaluation system; using a potted plant flooding identification method to process seedling stage flooding tolerance identification on 45 chrysanthemum closely related varieties, selecting 6 excellent varieties of strong flooding tolerance, and considering that the system can obtain reliable result. The invention establishes a fast and simple flooding tolerance evaluation system in first time and can evaluate and identify the flooding tolerance resources, to find the flooding tolerance level of chrysanthemum closely related varieties and establish a base for chrysanthemum flooding tolerance breeding and large-scale chrysanthemum varieties.

Description

1. Technical field [0001] The invention relates to an evaluation and identification method for waterlogging tolerance of chrysanthemums, belonging to the technical field of plant cultivation and breeding. 2. Background technology [0002] Chrysanthemum (Dendranthema × grandiflorum) originates in my country, is one of my country's top ten traditional famous flowers, and is also one of the world's four largest cut flowers and top ten potted flowers. There are more than 3,000 domestic chrysanthemum varieties (Li Hongjian, Shao Jianwen. "Chinese Chrysanthemum". Nanjing: Jiangsu Science and Technology Press, 1993, 4), with extremely rich flower types, flower colors, and plant types. The important flower species used have high ornamental and application value, and occupy a very important position in flower production. Chrysanthemum likes humus-containing, ventilated, well-drained sandy soil, avoiding waterlogging. However, China belongs to the continental monsoon climate, and th...
