Abstract:

Zingiberaceae is a perennial rhizomatous herbaceous plant with great economic value used as food, spices, medicinal compounds, and ornamental plants, preservation of Zingiberaceae germplasm resources is crucial for breeding and commercial production. To clarify the current research status on the conservation of genetic resources in Zingiberaceae plants, this paper specifically introduces the three main methods(ex situ conservation, tissue culture preservation, and cryopreservation) used for preservation of Zingiberaceae germplasm resources. Future prospects of Zingiberaceae germplasm preservation are analyzed, aiming to provide reference for the healthy and rapid development of Zingiberaceae industry. Cryopreservation technology, which has many advantages compared with the traditional methods, has been proven to be a new technique for plant pathogen elimination with successful application on several plants, and can provide a technical support to low conservation rates in Zingiberaceae plants elimination.

Key words: Zingiberaceae plants, germplasm resources, ex situ conservation, tissue culture preservation, cryopreservation
