一些过去被错划为顽拗型种子,现在都可以通过低温低湿而长期保存。如采用国际植物遗传资源委员会(以下简称IBPGR)推荐的长期贮藏条件:种子水分5%,贮藏温度—18℃,中期贮藏条件:种子水分6～9%,贮藏温度0～10℃等(Cromarty等,1982)。而一些有疑问的需待进一步证实外,自然界确实存在着顽拗型种子。顽拗型种子的脱水损伤和不耐低温特点决定了其只能短期贮藏,这给许多经济价值较高的果实、食用作物种子,以及种质资源的运输和贮藏带来了极大的困
Some of the past are wrongly classified as recalcitrant seeds, and now can be long-term preservation through low temperature and low humidity. For example, the long-term storage conditions recommended by the International Commission on Plant Genetic Resources (IBPGR) are as follows: seed moisture 5%, storage temperature -18 ° C, medium-term storage conditions: seed water 6 to 9%, storage temperature 0 to 10 ° C , 1982). However, some doubts need to be further confirmed, the existence of recalcitrant seeds in nature. The recalcitrant dehydration damage and inability to hypothermia of recalcitrant seeds have determined that they can only be stored for a short period of time, which has caused great difficulties for many high-value fruits, seeds for food crops and transportation and storage of germplasm resources
