Determination of free ammonium and asparagine and glutamine amide-nitrogen in extracts of plant tissue.
A relatively simple and rapid procedure for the measurement of free ammonium and the amides in plant extracts is described. The method was developed by combining a cation-exchange method for blood ammonia with a differential acid-hydrolysis procedure for asparagine and glutamine amide-nitrogen. The recovery of standard samples (100-400 mug of ammonium- or amide-nitrogen) of free ammonium, aspar...

متن کاملNitrogen Nutrition of the Pineapple Plant ,
Unpublished studies in the files of the Pineapple Research Institute of Hawaii indicate that under present cultural conditions the .pineapp1e plant displays superior performance with a foliar applied combination of ammonium and nitrate nitrogen than with either form of nitrogen alone. The studies presented here were undertaken to evaluate ammonium nitrate as a nitrogen source under different so...
متن کاملDiuretic Potential of Whole Plant Extracts of Pergularia daemia (Forsk.)
The whole plant, Pergularia daemia (Family: Asclepediaceae), was extracted with 50% alcohol and a fresh batch of the plant material was successively extracted with petroleum ether, ethyl acetate and n-butanol to determine its diuretic activity. The diuretic activity of the different extracts at a dose of 400 mg/Kg was assessed orally in rats with furosemide as a standard drug using Lipschitzs t...
