germplasm resource bank

germplasm resource bankAlso known as a gene bank, it is a warehouse that uses instruments and equipment to control the storage environment and store crop germplasm for a long time.
Excavating and collecting seeds of various crop varieties, scientifically storing them, so that the germplasm still has its original genetic characteristics and high germination ability after decades or even hundreds of years, is of great significance for variety improvement, cultivating high-yield, high-quality, and stress resistant new varieties, and providing rich germplasm and research materials for theoretical research in biology.

According to the user's usage purpose, Ningbo Pront has created short-term storage, medium-term storage, long-term storage, automated access short-term storage, automated access medium-term storage, Double Fifteen drying room, duplicate storage, temporary storage, test tube seedling preservation storage, etc., providing diversified storage solutions for different germplasm resources.
Short term storage, with two temperature ranges of 0-4 ℃/4-8 ℃ and humidity ≤ 50RH, can preserve germplasm for 3-5 years; Mid term storage, with a temperature maintained between -4 ℃ and 4 ℃, humidity ≤ 40RH, and a storage period of over 10 years; Long term storage, with a temperature maintained between -18 and -15 ℃, humidity ≤ 40RH, and a storage period of over 50 years.
Automated storage and retrieval of short-term warehouses, with two temperature ranges of 0-4 ℃/4-8 ℃, humidity ≤ 50RH, and a storage period of 3-5 years; Automated storage and retrieval of mid-term storage, with temperature maintained between -4 ℃ and 4 ℃, humidity ≤ 40RH, and a storage period of over 10 years. Both short-term and mid-term automated access databases have added robot automated access functionality. The access command is issued by the control center without manual operation, which can accurately locate the target germplasm resources and achieve access operationsgermplasm resource bankCombining with modern technology.
Double Fifteen Drying Room, temperature 15 ± 2 ℃, humidity ≤ 15 ± 3RH, reducing seed storage moisture content and extending germplasm preservation time; Temporary storage facility, with temperature between 8-12 ℃ and humidity ≤ 60RH, used for temporary preservation of newly collected germplasm resources; Duplicate library, temperature between -18 ℃ and -15 ℃, humidity ≤ 40RH, storage period of more than 50 years, used for germplasm backup storage and national emergency use; The test tube seedling storage facility has a temperature range of 4-35 ℃, humidity range of 45-80RH, optional light intensity range of 0-5000lx, optional light duration range of 0-24h/d, and a storage period of more than 6 months. It is mainly used to preserve agricultural biological germplasm resources that cannot be stored in seed form.
