Apr 6, 2025 · Relative Water Content (RWC): RWC measures the water content of a tissue relative to the weight of the tissue at full turgor, and is calculated using the equation: RWC =...

One of the most successful adaptations to such extreme drought is desiccation tolerance—the ability to survive water loss to 10% relative water content (RWC), equivalent to 0.1 g H 2 O/g dry weight, and revive full metabolism when rehydrated [3]. Such plants are commonly called resurrection plants [4].

During desiccation, sensitive species start to die below an approximate relative water content of 55%, whereas tolerant species do not. Cells of all orthodox seeds must possess a core set of mechanisms to protect them from desiccation- and rehydration-induced damage.

There are three main ways in which insects can increase their tolerance to desiccation: by increasing their total body water content; by reducing the rate of body water loss; and by tolerating a larger proportion of overall water loss from the body. [1]

Dec 1, 2010 · Desiccation tolerance is defined as the ability to survive the removal of all, or almost all the cellular water without irreversible damage. It confers to dried organisms the ability to survive extreme conditions of the environment and to …

Desiccation tolerance, as opposed to drought tolerance, which involves surviving moderate water loss (e.g. 90% relative water content [RWC]), is the ability to survive absolute water contents of 0.1 g H 2 O g −1 [2].

Rapid dehydration increased the sensitivity of embryonic tissues to desiccation as indicated by high critical water contents, below which desiccation damage occurred. Cumulative desiccation stress increased sharply under slow drying conditions, which …

Feb 1, 2009 · In desiccation-tolerant plants vegetative organs can dry to about 4–13% relative water content, while desiccation-sensitive plants die when their relative water content drops below 20–50%.

Desiccation tolerance, as opposed to drought tolerance, which involves surviving moderate water loss (e.g. 90% relative water content [RWC]), is the ability to survive absolute water contents of 0.1 g H. 2Og.

Detached fronds from healthy AR fern were fully hydrated, subsequently desiccated, and rehydrated under in vitroconditions. During the desiccation process, the relative water content (RWC) of detached fronds decreased to as low as 16% after 4 hours with intense inward curving.
