体外培养苗被认为是珍贵植物种群种质保存的一种理想方法,有效的体外保存方法有多种,而冷藏则是短期或中期保存最简单、实用的一种方法。冷藏还能使再培养的间隔时间从一般的1个月延长到1年甚至更长。作者将这种冷藏方法应用于伞形科药用植物北沙参的体外培养中。
In vitro culture of seedlings is considered as an ideal method for the conservation of precious plant germplasm. There are many effective methods of in vitro preservation, while the cold storage is the simplest and practical method of preservation in short-term or medium-term. Refrigeration can also extend the interval of re-culture from normal 1 month to 1 year or longer. The authors apply this method of cold storage in the Umbelliferae medicinal plant Bemisia ginseng in vitro culture.
