GB/T 36774-2018 in English

I. Background and significance of standard formulation

As an important invasive alien species, the quarantine and identification of garlic mustard eggplant (Solanum sisymbriifolium Lam.) is of great significance to the protection of my country's agricultural ecological security. The formulation of this standard is based on GB/T1.1-2009 rules, proposed by the National Technical Committee for Plant Quarantine Standardization, and completed by multi-departmental collaboration.

This standard is applicable to the quarantine and identification of garlic mustard eggplant in plant raw grains, seeds and other products, and clarifies the specific process and methods from sample collection to laboratory testing.

II. Key points of quarantine and identification technology for garlic mustard eggplant

1. Sample collection and processing

According to the requirements of GB/T 36774-2018, samples need to be fully mixed and sampled by the quartering method. When the sample volume is less than 1kg, it is recommended to conduct a full inspection.

2. Laboratory identification steps

First, observe the morphological characteristics of the plant with the naked eye, such as the prominent characteristics of the stem, leaves, inflorescence and other structures. For suspected samples, a stereo microscope or scanning electron microscope is required for microscopic observation to confirm its external and internal structural characteristics.

3. Identification basis

The morphology of the complete plant or mature seeds is used as the identification basis. Pay special attention to the berry shape, color changes (from green to vermilion) of garlic mustard eggplant, and the reticulation and hilum characteristics on the seed surface.

III. Analysis of Technological Evolution

1. Advances in Analytical Methods

Compared with traditional manual experience identification, GB/T 36774-2018 introduces more systematic laboratory testing processes and instrument support, such as electronic balance, electric sieve, etc.

2. Future Development Direction

With the development of science and technology, it is recommended to introduce more modern detection methods into the standard, such as DNA barcoding technology and AI-assisted recognition system, to improve identification efficiency and accuracy.

IV. Implementation Recommendations

1. Specimen Preservation and Management

Number and label the detected specimens strictly in accordance with the requirements of the standard, and properly preserve them for at least 6 months. It is recommended to establish an electronic specimen management system for subsequent query and research.

2. Quarantine staff training

Regularly organize quarantine identification technical training, focusing on improving the operational standardization and technical level of grassroots inspection and quarantine personnel.

3. Information construction

It is recommended to develop a digital testing platform based on this standard, integrating the entire process of sample collection, processing, testing and result determination, and realizing efficient management of quarantine work.
