Hyperhydricity in micropropagated carnation shoots: the role of oxidative stress
Physiologia Plantarum, 2004The physiology of hyperhydricity in relation to oxidative stress, mineral nutrients, antioxidant enzymes and ethylene has been studied in three micropropagated carnation cultivars under experimentally induced hyperhydricity. A marked increase in Fe content in comparison with normal tissues was observed in the hyperhydric tissues from the three ...

Control of hyperhydricity of mango somatic embryos
Plant Cell, Tissue and Organ Culture, 1995Hyperhydricity of immature somatic embryos has been a limiting factor for the development of highly embryogenic suspension cultures of many important mango cultivars. Reversion of hyperhydricity was achieved in two ways: 1) heart-stage somatic embryos (2–3 mm length) were partially dehydrated under controlled conditions at high relative humidity (RH ...

Control of hyperhydricity in micropropagated apricot cultivars
In Vitro Cellular & Developmental Biology - Plant, 2001The effects of different factors on the control and reversion of hyperhydricity during the in vitro propagation of Prunus armeniaca were studied. Treatments that decreased the hyperhydricity but did not affect micropropagation rates were the use of the bottom cooling system for 1 or 2 wk and agargel as gelling agent in ‘Helena’, whereas the best ...

Effects of water deprivation and hyperhydration in pregnant and lactating goats
Acta Physiologica Scandinavica, 1982The response to 30 h water deprivation was studied in 7 goats during the last month of pregnancy and during lactation with anestrus as the control period. Plasma osmolality and plasma Na concentration increased by about 4% in pregnant and lactating goats and by about 2% in anestral goats.

Glycerol hyperhydration: hormonal, renal, and vascular fluid responses
Journal of Applied Physiology, 1995Glycerol ingestion has been shown to mediate hyperhydration; however, the mechanism(s) responsible for this improved fluid retention is not well understood. This study examined the hormonal, renal, and vascular fluid responses to glycerol hyperhydration in 11 resting male volunteers who ingested one of two experimental solutions and then a water bolus.

Applied Physiology, Nutrition, and Metabolism, 2015
Before 2010, which is the year the World Anti-Doping Agency banned its use, glycerol was commonly used by athletes for hyperhydration purposes. Through its effect on osmoreceptors, we believe that sodium could prove a viable alternative to glycerol as a hyperhydrating agent.

Glycerol Use in Hyperhydration and Rehydration: Scientific Update
2012Glycerol ingestion creates an osmotic drive that enhances fluid retention. The major practical applications for athletes are to either (i) hyperhydrate before exercise so that they have more fluid to be lost as sweat during subsequent performance, thereby delaying the progression of dehydration from becoming physiologically significant, or (ii) improve

Hyperhydration induced by glycerol ingestion: hormonal and renal responses
Canadian Journal of Physiology and Pharmacology, 2002The simultaneous time courses of hydromineral hormones (reninaldosterone system, arginine vasopressin, and atrial natriuretic peptide) and renal responses were examined during and after the completion of hyperhydration induced by glycerol and fluid ingestion.

A procedure to prevent hyperhydricity in cauliflower axillary shoots
Plant Cell Tissue and Organ Culture, 1999Cauliflower axillary shoots exhibited hyperhydric status when cultured in vitro under usual conditions with growth regulators, resulting in poor survival during transfer to the glass-house. A pretreatment soaking of curd explants in sucrose −2 MPa for 24 h was sufficient to induce axillary bud break.
