温带作物的种子,必须含有一定水分才能保持其活性,但这样贮存的种子易发霉腐烂。现在有许多措施既能保持种子活性,又能够多年贮藏。例如,小麦种子在-322°F液氮中可贮存100年以上。但许多热带作物及部分温带作物的种子含水量极高,如果按一般温带作物种子的处理方法风干贮存,就会因失水而失去活性。采用“快速风干法”很有希望解决这一问题,即切下种胚或生长点,进行加压风干 The seeds of temperate crops must contain a certain amount of water to maintain their activity, but the seeds thus stored tend to mold rot. There are many measures to preserve seed activity and to store for years. For example, wheat seeds can be stored in liquid nitrogen at -322 ° F for over 100 years. However, many tropical crops and some temperate crops have extremely high water content and, if stored as air-dried in common temperate crop seeds, lose their activity due to water loss. The use of “fast drying method” is very promising to solve this problem, that is cut embryo or growing point, the pressure of air-dried
