Abstract: To preserve eminent cell lines with stable metabolism, the cryopreservation of suspension culture cells by vitrification in Camellia sinensis has been preliminarily investigated in this article. It showed that the preculture for four days was best, loading with 60% PVS2 in freezing bath for 20 minutes was optimal. Treating with 100% PVS2 dehydration in freezing bath for 60 minutes was suggested. The cryopreservation of suspension culture cells warmed in 40℃water bath had the highest survival rate. The cells’ survival rate was as high as 76% when these parameters were adopted through the whole trial. The procedure of cryopreservation of suspension culture cells by vitrification in Camellia sinensis was preliminarily established.
