Examplesofdesiccationdesiccation A number of protective mechanisms associated with seeddesiccationtolerance have been identified through studies on acquisition and loss of desiccation tolerance in orthodox seeds. From theCambridge English Corpus Additionally, indesiccation-sensitive seeds, protective antioxidant systems may also fail. From theCambridge English Corpus The existence of discrete levels of critical water potential is suggestive of specific stresses that cells must accommodate during the acquisition ofdesiccationtolerance. From theCambridge English Corpus Specific mechanisms associated withdesiccationsensitivity of recalcitrant seeds are still not resolved. From theCambridge English Corpus The pericarp appears to form the main natural barrier todesiccationunder both natural and artificial conditions of seed storage. From theCambridge English Corpus The correlation between the degree ofdesiccation, temperature and the level of occurrence of these bacteria in natural environments has yet to be made. From theCambridge English Corpus It can tolerate high temperatures,desiccation, ultraviolet light and ionising radiation doses 1,000 times higher than would be fatal to humans. From theCambridge English Corpus There are also some cracks to be seen: these represent just artifacts due todesiccationoccurring during scanning microscopic investigation. From theCambridge English Corpus Samples were kept in a humidity chamber for extended incubation periods to preventdesiccationof the relatively thin agar layer. From theCambridge English Corpus High humidity is a prerequisite for tick survival since they are susceptible todesiccationwhen questing for hosts on vegetation. From theCambridge English Corpus Here eggs are likely to be at lower concentrations and have a lower viability due to greater exposure todesiccationand ultraviolet radiation. From theCambridge English Corpus This study was undertaken to determine whether extensive vacuolation and high metabolic activity can be contributory factors indesiccationsensitivity. From theCambridge English Corpus The ability to withstanddesiccationmay also depend upon increased amounts (or a heightened capacity to synthesize) molecules which stabilize membranes. From theCambridge English Corpus Desiccationtolerance across life forms interpreted as having nucleated from the surrounding, denser phase. From theCambridge English Corpus In cotyledons, methyl esterification ranged from 25 to 40 mole% and was 31 mole% afterdesiccation.
