Recently there has been much interest to utilize in vitro cultures for the conservation of germplasm and low temperature storage has been successfully applied to a large number of plant species (Bajaj 1986, 1991).

In the present communication in vitro-grown explants and plantlets of Chrysanthemum morifolium and Pentunia hybrida stored in a refrigerator for six years survived and the plantlets underwent normal flowering.
