Adaptation to water deficit in chickpea breeding lines by osmoregulation, relationship to grain yields in the fields.
1978), but had no effect on the SON, a region involved in osmoregulation, parturition, and lactation (Higuchi and Okere 2002).
These variables were measured because tissue water content and potassium concentration are associated with osmoregulation, and tissue nutrient content indicates nutrient history of the algae.
The first thing to understand is that koi need a high level of body salts, and the reason for this is a process called osmoregulation.
However, it is essential to have environmental calcium in the water to help fish with the maintenance of constant osmotic pressure in their systems or osmoregulation. Sodium and potassium, essential salts in fish blood are critical for normal heart, nerve, and muscle function.
This study investigated the physiological and biochemical changes in cellular osmoregulation when Chlorococcum hypnosporum (L.) was grown in high saline environments.
-- Osmoregulation experiments were conducted on Rangia cuneata, over a range of salinities from <0.5 ppt to 20 ppt, to determine if the reproductive stage and high gonadal biomass affected osmoregulation ability and survival.
Another weakness is that some concepts are described in insufficient detail (e.g., osmoregulation, Von Bertalanffy equation) and should be omitted rather than leaving students in a fog.
There is, however, more controversy regarding changes in osmoregulation of vasopressin (AVP) secretion and the ability to conserve and excrete water appropriately.
Moreover, gills perform numerous functions, such as respiration, osmoregulation, excretion of nitrogenous residues and acid-base balance, so that functional impairment of the organ can damage fish health (Barja-Fernandez et al.).
and platelet, has several physiological roles including membrane stabilization, osmoregulation and cytoprotective effects, antioxidant and anti-inflammatory actions as well as modulation of intracellular calcium concentration and ion channel function.
Gills are the most important organ of the fish, play multifunctional role in performing dynamic functions such as osmoregulation, acid-base balance, respiration and excretion of nitrogenous wastes (Evans et al., 2005).
