Ultrastructural changes in rhizome parenchyma of Polypodium vulgare during dehydration with or without abscisic acid pretreatment

Common polypody (Polypodium vulgare L.) belongs to desiccation-tolerant ferns. The structure of storage parenchyma of their rhizome was examined by transmission electron microscopy after dehydration and subsequent rewetting. Analysis revealed that treatment with supplemental abscisic acid resulted in protection of cells against ultrastructural damage compared to untreated ones. Dehydration rate appears to modify the ability of rhizome parenchyma to stand water stress.
