Tortula ruralis is the most studied desiccation-tolerant species in established expressed sequence tag databases and will be an important experimental model in investigating vegetative desiccation tolerance.

山墙藓是耐旱研究较多的一个种，已建立了表达序列文库，将会成为耐旱研究的重要模式植物。

The results showed that O. fragrans seeds were desiccation-sensitive as the seed viability declined to 6% when the seed moisture content was reduced to 11.6%. The seed electrical conductivity increased with the declining moisture content, a sign, which was caused by increasing cell membrane cleavage. Superoxide dismutase activity decreased rapidly during desiccation; but peroxidase activity increased to the maximal value when dehydration for 12 h, then declined rapidly when seeds were dehydrated more than 12 h.

结果表明：'紫柄籽银桂'种子不耐脱水，种子生活力随着含水量的下降而降低，种子含水量下降到11.6%时，生活力仅为6%；自然脱水过程中，种子细胞膜系统受到损伤，相对电导率不断上升；种子内SOD活性随着含水量下降而呈总体下降的趋势；POD先呈波动性上升，脱水12 h时达到最大值，之后急剧下降。

The soil desiccation as a soil degradation is existed widely in the artificial forest of hot-dry river valley, for instance the simple community structure, the low plant species diversity and a long time - soil desiccation.

To investigate the relationship between the tolerance to dehydration and superoxide dismutases in Pachira macrocarpa, fresh mature seeds were pretreated with a 12 h DDTC and subjected to 3~20 h desiccation silica gel at 25℃. The results showed that 20 mmolL^(-1) diethyldithiocarbamate treatment inhibited efficiently SOD and SOD activity in seeds and reduced tolerance of seeds to water deficit, which was evidenced with increases in electrical conductivities and malondialchehy of the seeds, and a rapid decrease of the seed vigor during desiccation.
