《GB/T 31799-2015银毛龙葵检疫鉴定方法》由TC271（全国植物检疫标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了银毛龙葵(Solanumelaeagnifolium Cav.)的检疫鉴定方法。
本标准适用于所有植物原粮、种子及其他产品中混杂的银毛龙葵以及杂草监测工作中银毛龙葵的检疫鉴定。
Introduction
1. Background and significance of standard formulation
Solanum elaeagnifolium Cav. is a highly invasive quarantine weed widely distributed in many regions around the world. Its strong adaptability and reproductive capacity make it a major threat to agricultural production. The formulation of this standard aims to standardize the quarantine identification process of Solanum elaeagnifolium Cav. to ensure accurate identification and control of its spread in plant raw materials, seeds and other products.
2. Comparison of standard frameworks
| Standard dimensions | Scope of application | Technical requirements | Implementation effect |
|---|---|---|---|
| Morphological identification | Silver-haired Solanum mixed in all plant raw materials, seeds and other products | Identification by observing the morphological characteristics of plants, leaves, inflorescences and berries | Efficient and accurate, suitable for preliminary screening |
| Molecular biology identification | Plant bodies suspected of silver-haired Solanum | Accurate identification based on DNA barcoding technology (PCR and sequence analysis) | High precision, suitable for complex samples |
| Combination of on-site quarantine and laboratory inspection | Inbound and outbound plants and their products | \nCombination of on-site observation and laboratory molecular detection | Full coverage, reducing the risk of missed detection |
3. Analysis of technological evolution
The quarantine and identification technology of Solanum argentea has evolved from morphological observation to molecular biological detection. In recent years, methods based on DNA barcoding technology (such as PCR and high-throughput sequencing) have gradually become mainstream, significantly improving the accuracy and efficiency of identification. In particular, the Levin subgenus system mentioned in the standard clarified the evolutionary position of Solanum argentea and the relationship between its closely related species by constructing a phylogenetic tree, providing a scientific basis for molecular identification.
4. Implementation Suggestions
1. Improve inspection and quarantine capabilities: Strengthen laboratory construction, equip with advanced instruments and equipment (such as PCR instruments, high-speed refrigerated centrifuges, etc.), and train professional and technical personnel.
2. Strengthen international cooperation: Promote international mutual recognition and cooperation on the quarantine standards for Solanum argenteum, and share identification technology and experience.
3. Promote standardized processes: Promote this standard at key links such as entry and exit ports and agricultural product production bases to ensure its effective implementation.
