abstract：:O(2) consumption by the desiccation-tolerant moss Tortula ruralis and the desiccation-intolerant Cratoneuron filicinum increased markedly during the latter stages of desiccation. ATP content of the mosses during desiccation was not correlated with O(2) consumption, but was influenced by the rate at which the mosses lo...
