is one of the most popular flower crops worldwide, and some species are also used as vegetables and medicines. The availability of and easy access to diverse genetic resources are essential for plant genetic improvements. Cryopreservation is currently considered as an ideal means for the long-term preservation of plant germplasm. Over the last two decades, great efforts have been exerted in studies of cryopreservation and progress has been made in the successful cryopreservation of pollen, seeds and shoot tips in . Genes that exist in including those that regulate flower shape, color and size, and that are resistant to cold stress and diseases caused by fungi and viruses, provide a rich source of valuable genetic resources for breeding programs to create novel cultivars required by the global floriculture and ornamental markets. Successful cryopreservation of spp. is a way to preserve these valuable genes. The present study provides updated and comprehensive information about the development of techniques that have advanced cryopreservation. Further ideas are proposed to better direct future studies on cryobiotechnology.
是全球最受欢迎的花卉作物之一，一些品种还被用作蔬菜和药物。获取多样的遗传资源并能方便地利用这些资源对于植物遗传改良至关重要。目前，超低温保存被认为是长期保存植物种质的理想方法。在过去二十年里，人们在超低温保存研究方面付出了巨大努力，并在成功超低温保存花粉、种子和茎尖方面取得了进展。中存在的基因，包括那些调控花的形状、颜色和大小的基因，以及抗冷胁迫和抗真菌及病毒引起的病害的基因，为育种计划提供了丰富的宝贵遗传资源，以培育全球花卉栽培和观赏市场所需的新品种。成功超低温保存物种是保存这些宝贵基因的一种方式。本研究提供了有关推动超低温保存技术发展的最新综合信息。还提出了进一步的想法，以更好地指导未来关于超低温生物技术的研究。
