[Abstract]  Filmy ferns can desiccate and recover after rehydration to resume photosynthesis. Slow and fast desiccation rates were compared in filmy fern fronds to determine whether structural or physiological differences may occur between desiccation rates. Slow desiccation is considered to be more similar to natural conditions experienced by plants that grow under the forest canopy. A fast desiccation rate will help to understand whether slow desiccation is important for recovery and viability. [摘要]  薄膜蕨类植物可以干燥并恢复后恢复光合作用。 在膜状蕨叶中比较慢速和快速干燥速率以确定干燥速率之间是否可能发生结构或生理学差异。 慢速干燥被认为与森林冠层下生长的植物所经历的自然条件更相似。 快速干燥速率将有助于了解缓慢干燥对恢复和生存能力是否重要。

【背景】Hymenophyllaceae是一个附属蕨类植物家族,高度流行于阴暗潮湿的森林(图1)。这种薄膜蕨类植物的一些种类在干燥时可以存活至20%的相对含水量,在这种状态下保持较长时间,并且在再水化后存活(图2)(Garcés等人,, 2018年)(见例子timelapse,视频1)。
