Introduction
1. Standard Overview
GB/T 43645-2024 "Guidelines for the Construction and Conservation of Flower Germplasm Resources" is my country's first national standard specifically for the protection of flower germplasm resources. It aims to standardize the construction and management of germplasm resource banks and ensure the long-term preservation of flower genetic diversity.
2. Comparison of standard frameworks
| Standard dimensions | In situ storage | Ex situ storage | Facility storage |
|---|---|---|---|
| Applicable objects | Traditional precious flowers, rare and endangered flowers | Local specialty flowers that are easy to lose and have a narrow distribution | Special germplasm resources that cannot be preserved naturally |
| Preservation methods | Natural conditions in the original habitat | Ex situ cultivation or facility simulated environment | Artificial control of temperature and humidity and other conditions |
| Advantages and disadvantages | High authenticity, but greatly affected by natural factors | Strong flexibility, but high cost | Precise control, but high technical requirements |
3. Implementation suggestions
Strengthen the awareness of germplasm resource protection:The government, scientific research institutions and enterprises should jointly attach importance to the protection and utilization of flower germplasm resources to avoid resource loss due to urbanization and climate change.
Improve the legal and regulatory system:Clarify the ownership, use rights and income distribution mechanism of germplasm resources, and crack down on illegal collection and trading.
Promote technological innovation:Develop preservation technologies suitable for different types of flowers, such as low-temperature storage, tissue culture, etc., to improve preservation efficiency and success rate.
