摘要
甘薯是重要的粮食及经济作物,其种质保存一般采用田间种质圃和离体试管苗保存两种方式。但因甘薯的生理特性及这两种保存方式本身存在的弊端,有必要开展新的保存方法研究。超低温保存是目前甘薯种质长期安全保存的最有效方式。本文对甘薯超低温保存的定义、方法及存在的问题和展望进行了论述,并对茎尖玻璃化法进行了详细介绍。
Sweet potato is an important food and cash crop, whose germplasms were mainly conserved in field genebanks and in vitro genebanks. It is required to develop new technology for long-term conservation of sweet potato germplasm because of its physiological characteristics and inherent drawbacks of the two conservation methods. Currently, cryopreservation is the safest and cost-efficient method for germplasm long-term conservation. In this paper, research progresses on the cryopreservation of sweet potato, such as different kinds of material and its cryopreservation methods, especially cryopreservation of shoot tips using vitrification method and some problems needing more research were introduced.
