Abstract

The invention provides a detection method of pumpkin place of origin. The method comprises the following steps: firstly constructing enzyme electrophoresis reference fingerprints of pumpkins of different known places of origin, and establishing the enzyme electrophoresis reference fingerprint of the to-be-detected pumpkin place of origin by using the same method, and then performing clustering analysis on the enzyme electrophoresis reference fingerprints and the enzyme electrophoresis reference fingerprint, computing a fingerprint dissimilarity coefficient C to obtain the place of origin of the to-be-detected pumpkin, wherein a migration rate Rf of the fingerprint is more than 0.2, the dissimilarity coefficient C is equal to 2w / (a+b), w represents enzyme band number with different two-phase comparison type in the to-be-detected pumpkin place of origin and the known pumpkin place of origin, and (a+b) represents the total enzyme band of respective two-phase comparison type. Through the detection method of pumpkin place of origin provided by the invention, the operation is convenient, and the atlas is visual, the pumpkin place of origin can be objectively and accurately reflected andclassified. The method is free from the limitation of pumpkin shape, size and growth time, the different parts such as the root, the stems, the leaves, the fruits, and the seeds of the pumpkin can bedetected so as to obtain the pumpkin place of origin.

Description

technical field [0001] The invention belongs to the technical field of pumpkin planting, and in particular relates to a method for detecting the origin of pumpkins. Background technique [0002] Pumpkin (scientific name: Cucurbita moschata (Duch.ex Lam.) Duch.ex Poiret) is a species of Cucurbita moschata (Duch.ex Lam.) Duch.ex Poiret, an annual vine herb, with stems often rooting at nodes, thick petioles, broad oval or oval leaves, Slightly soft, with raised veins, slightly thick tendrils, monoecious, strong fruit stems, with ribs and grooves, which vary from variety to variety, and there are often several longitudinal grooves outside, many seeds, long oval or oblong, with good food therapy effect. [0003] Pumpkin cultivars are rich in resources. In the prior art, most of them are classified by plant morphological characteristics. Plant morphology is to study the internal and external morphology and structure of plants, the formation and development of organs, cells, tissu...
