植物遗传资源保存中,低温、低种子含水量是延长种质贮藏寿命的主要因素。国际植物遗传资源委员会(IBPGR)推荐种子含水量5～7%(大豆为8%)为种质中长期贮藏的较理想条件。因此,对入库贮藏种子进行干燥是种质库的一项重要工作内容。一、种子干燥方法种子干燥方法有下面几种类型:空气或太阳干燥,冷冻干燥法,吸收类型干燥法,热空气干燥法等。太阳干燥,因会影响某些物种长期贮藏种子的生活力。冷冻干燥法用来干燥种子通常也被认为是不经济的。因此,在种质库,种子干燥普遍采用是热空气干燥法。但近年
In the conservation of plant genetic resources, low temperature and low seed water content are the main factors to prolong germplasm storage life. The International Commission on Plant Genetic Resources (IBPGR) recommended seed water content of 5 to 7% (8% of soybean) for medium and long-term storage of the ideal conditions. Therefore, it is an important work of genebank to dry the stored seeds. First, the seed drying methods Seed drying methods are the following types: air or sun drying, freeze-drying method, absorption type drying method, hot air drying method. The sun is dry because it affects the viability of long-term stored seeds in some species. Freeze-drying is also often considered uneconomical for drying seeds. Therefore, in the genebank, seed drying is commonly used is the hot air drying method. But in recent years
