Incipient freeze-thaw stress, in onion bulb scale tissue, is known to cause enhanced efflux of K+, along with small but significant loss of cellular Ca2+ (Palta et al., 1977a; Palta et al., 1977b). Based on these results Palta and Li (1978) proposed a hypothesis for possible sequence of events leading to cell death or recovery depending upon the initial injury (Palta and Li, 1978). According to this hypothesis, loss of cellular calcium was thought to play an important role in freezing injury. Recently we have presented evidence that loss of membrane/cellular Ca2+ occurs in the early stages of freezing injury in onion scale epidermal cells (Arora and Palta, 1988).
