Method for rapidly identifying and comprehensively evaluating polygonatum cyrtonema provenance based on multi-character principal component analysis

By using principal component analysis of multiple traits, combined with growth, physiological and medicinal traits, a weighted comprehensive score (CES) was calculated, which solved the problem of inconsistent quality of Polygonatum multiflorum germplasm and enabled rapid and scientific germplasm screening and breeding guidance.

AI Technical Summary

Technical Problem

Existing technologies cannot effectively solve the problem of inconsistent quality caused by mixed seed sources of Polygonatum multiflorum. Traditional experience-based identification methods are highly subjective, and single chemical index evaluation methods cannot fully reflect the comprehensive medicinal value of seed sources. Modern analytical techniques require large investments in equipment and are complex to operate, while molecular marker technology cannot directly reflect the quality of medicinal materials.

Method used

By employing multi-trait principal component analysis, the growth traits, physiological and biochemical traits, and medicinal component traits of plants were measured. After Z-score standardization, the principal component analysis model was used to reduce dimensionality and calculate the weighted comprehensive score (CES), thus achieving an objective and rapid evaluation of the seed source.

Benefits of technology

This enables a comprehensive and objective evaluation of Polygonatum multiflorum germplasm, shortens the screening cycle, reduces identification costs, provides scientific breeding guidance, and improves the overall quality of germplasm.

Abstract

The invention discloses a rapid identification and comprehensive evaluation method for a polygonatum cyrtonema provenance, and belongs to the field of improved variety breeding and quality control of traditional Chinese medicinal materials. The method systematically measures a plurality of specific biological traits covering three dimensions of growth, physiology and medicine. And carrying out standardization processing on the measured multi-dimensional data, carrying out dimensionality reduction by using a principal component analysis model, constructing an evaluation model capable of comprehensively reflecting the comprehensive quality of the provenance, and calculating a quantitative comprehensive evaluation score. The score can objectively and scientifically divide different provenances into four different quality grades including excellent, good, common and to-be-improved quality grades. The method has the beneficial effects that the strong positive correlation between the easily measured growth traits of the overground part and the medicinal component content of the underground rhizome for determining the final quality of the medicinal material is established, so that the rapid, predictive and non-destructive early screening of the provenance quality is realized.
