Plant Vitrification Solution 2 (PVS2)  and  Plant Vitrification Solution 3 (PVS3)

Explanation:

Cryo-preservation or cryo-conservation is defined as the process of preservation of all cellular and structural elements such as cells, organelles, tissues, organs, or any other biological constructs by cooling to very low temperatures.
