耐貯型種子:

    耐貯型種子為一般穀類、蔬菜等小粒種子,可在低溫、低濕的環境長期貯藏,依保存目的不同,分別貯藏於長期庫、中期庫及短期庫。

a.長期貯藏庫:

     溫度為-12±2,相對濕度30±3%,本庫主供貯藏基礎材料,預期可貯24萬份種原,進入本庫材料需先經嚴格鑑定及精選。本庫材料不對外交換,僅定期取樣進行發芽力檢測,或供更新之用。本庫之目的為使入庫之種原能永續保存。預估於本中心長期庫之環境下,種子貯藏壽命可達3050年。

b.中期貯藏庫:

     溫度為1±2,相對濕度40±3%,本庫專供貯藏常用材料,預期可貯25萬份種原;本庫種原供分送交換、繁殖和評估,並作為基礎材料補充用,為保持所貯藏材料之品質,本庫材料需定時進行種子發芽率檢測及種子更新。

 

Orthodox type:

   These include small-seeded grain crops and vegetables. They can be stored for a long time under low-temperature and low-humidity environment and are separately stored in long, medium and short-term storerooms in accordance to the purpose of storage.

a. Long-term storage:

With storage conditions of -12±2 and 30±3% RH, long-term RH, long-term preservation is provided mainly for the comprehensive base collection. Plant germplasm with careful collection, identification, and selection precedes before storage. About 240,000 accessions will be stored. Stored materials will not be used for exchange; they are only preserved for regenerating fresh seed and periodically examined for seed viability level. The purpose of this storage is for the perpetuation of the seed stocks. Life expectancy of seed preserved in long-term storage at this Center will last from 30 to 50 years.

b. Medium-term storage:

With storage conditions of 1±2 and 40±3% RH, this storage is provided solely for the seeds of actively used materials. This storage will accommodate 250,000 accessions or samples that will be used for distribution, exchange, multiplication, and evaluation purposes. The seeds will also supplement the base collection in long-term storage. Regular germination tests and seed regeneration are required for materials in this storage in order to maintain their viability.
