The relationship between water binding and desiccation tolerance in tissues.
In an effort to define the nature of desiccation tolerance, a comparison of the water sorption characteristics was made between tissues that were resistant and tissues that were sensitive to desiccation. Water sorption isotherms were constructed for germinated and ungerminated soybean axes and also for fronds of several species of Polypodium with varying tolerance to dehydration. The strength...
متن کاملStability and Synthesis of Phospholipids during Desiccation and Rehydration of a Desiccation-Tolerant and a Desiccation-Intolerant Moss.
The fatty acid composition of the phospholipids from the desiccation-tolerant moss Tortula ruralis (Hedw.) Gaertn, Meyer and Scherb and the desiccation-intolerant moss Cratoneuron filicinum has been determined. No changes in composition occur in either moss as a consequence of rapid drying, but, after slow drying, there is a decline in some unsaturated fatty acids. Upon rehydration of T. rurali...
متن کاملHybrid sunflower seed yield, composition and deterioration after chemical desiccation
The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...
متن کاملThe effect of desiccation on water management and compartmentalisation in scorpions: the hepatopancreas as a water reservoir.
Scorpions of the Family Buthidae have lower water loss rates (WLR) and enhanced osmoregulatory capacities in comparison with sympatric species of F. Scorpionidae. In this study we followed changes in water content of different body compartments in four scorpion species under prolonged desiccation conditions. The high initial WLR previously reported for Scorpionidae result in rapid depletion of ...
متن کاملWater activity and glass transition temperatures of disaccharide based buffers for desiccation preservation of biologics
Studying the thermophysical properties of disaccharide based ternary solutions are gaining increasing importance because of their role as excepients in preservation protocols for biologics in general and mammalian cells in particular. Preservation strategies involve not only cryopreservation, but novel approaches like room temperature vitrification and lyophilization. In this study we investiga...
