Roots of decapitated maize seedlings (Zea mays L.) were exposed for 12 hours to 1.0 millimolar KNO(3) (98.5 atom per cent (15)N) in the presence and absence (control) of 0.1 millimolar p-fluorophenylalanine (FPA), an analog of the amino acid phenylalanine. FPA decreased nitrate uptake but had little effect on potassium uptake. In contrast, accumulation of both ions in the xylem exudate was grea...

The inner medullary collecting duct (IMCD) effects net sodium reabsorption under the control of volume regulatory hormones, including atrial natriuretic peptides (ANP). These studies examined the mechanisms of sodium transport and its regulation by ANP in fresh suspensions of IMCD cells. Sodium uptake was inhibited by amiloride but insensitive to furosemide, bu-metanide, and hydrochlorthiazide....

The co-inoculation of mulberry with phosphate solubilizing micro-organisms, nitrogen fixing bacteria and arbuscular mycorrhiza has influenced its macronutrient uptake through leaf. The data revealed that maximum nitrogen (484.12 kg /ha) , phosphorus (59.83 kg /ha) and potassium (244.61 kg/ha) uptake through leaf has taken place due to co-inoculation treatments as compared to the un inoculated t...

When insulin is infused into a brachial artery of normal men at a constant rate of 100 uU per minute per kg of body weight, there appears rapidly evidence of increased glucose uptake by forearm muscles and by forearm adipose tissue, a shift from net potassium loss to potassium uptake by muscle, increased K uptake by adipose tissue, and marked decrease in release of free fatty acids (FFA) by for...

Potassium formate, the potassium salt of formic acid, is an inexpensive, non-corrosive, non-toxic, and bio-degradable desiccant that has not been considered thus far in atmospheric water harvesting applications.ster proposed utilizes aqueous solution formate as medium for moisture absorption during night when ambient relative humidity high, desorption absorbed from day using solar energy. A sim...

To study the short-term uptake of potassium across the basolateral membrane into individual tubule cells, rubidium was used and measured by electron microprobe analysis. Changes of rubidium uptake were interpreted to reflect altered sodium entry and basolateral Na-K-ATPase activity. The effects of hydrochlorothiazide, amiloride and furosemide were determined in saline-loaded animals. Hydrochlor...

mycorrhizal symbiosis increase nutrient uptake and enhance plant growth by elaborating root system. the positive effects of mycorrhizal symbiosis on the growth, physiology and ecology of various plants have been recognized. the symbiotic relations between mycorrhizal fungi and date palm with regard to nutrient uptake by this plant have not yet been explored and studied in iran. this project was...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in tropical and subtropical areas. this flower has forth order in cut flower and second order in bulbous plants production in iran. plant spacing and nitrogen necessity are the most important factors for tuberose quality and quantity. in this study, field experiment carried out as factorial design in randomized complete ...

The experiment was conducted at Zonal Agricultural Research Station, Vishwesharaiah Canal Farm, Mandya during 2018-19 to study the nutrient uptake (NPK), use efficiency and grain yield of rice (Oryza sativa L.) in different establishment methods under varied management practices. laid out a split plot design with three replications. main comprised viz., semi dry rice, drum seeded transplanted w...
