Interactions Between Intact Barley Plants . Potassium and Calcium in Their Absorption by I . Effects of Potassium on Calcium Absorption '
A bstract. Increasing concentrations of K (20, 200, 2000 ,uM) in the nutrient solution depressed Ca content and concentration in barley plants growing in nutrient solutions of low Ca concentrations (250 and 2500 Mm). Increasing K from 20 to 200 AM depressed Ca absorption more than increasing K from 200 to 2000 FM K. The strong depression of Ca absorption by low concentraltions of K must involve...
متن کاملCalcium inhibition of potassium absorption in corn roots.
Calcium (or magnesium) sulfate or chloride was found to inhibit energy dependent potassium transport in excised corn roots. This Ca(2+) inhibition of K(+) transport was most pronounced during the initial phases of transport. As the absorption periods were lengthened the effect of Ca(2+) gradually changed from an inhibition to a typical promotion (after about 30-45 mins) of K(+) transport. Kinet...
متن کاملResolution of Dual Mechanisms of Potassium Absorption by Barley Roots.
As long as ZiveqI << 1/4, the equilibrium remains close to the "valley state." According to equations (16) and (21), this requires fairly low temperatures (,A >> 1). Specifically, in experiments on persistent currents where v (the magnetic flux quantum number) is often a very large number (-.105, say), the condition is T > 1,8 may be written in the form of an expan...
متن کاملThe regulation of potassium absorption in barley roots.
The dynamics of changes in K(+) influx across the plasmalemma and of internal K(+) concentrations [K(+)](1) of intact barley (Hordeum vulgare) roots were examined as the roots were converted from ;high-salt' to ;low-salt' roots. Following the transfer of plants grown in 0.5 mm CaSO(4) solutions plus various concentrations of KCl to 0.5 mm CaSO(4) solutions, influx rates increased and internal K...
متن کاملEffects of Increasing Potassium Chloride and Calcium Chloride Ionic Strength on Pesticide Sorption by Potassium- and Calcium-Smectite
In aqueous suspension, the affinity of many pesticides for smectites is influenced by the clay properties such as surface area, surface charge density and location, exchangeable cations, and hydration status of exchangeable cations in clay interlayers. The amount and the type of salts present in the aqueous phase influence clay quasicrystal structures and hydration status, which we hypothesize ...
