standard of calcium estimation in plant by flame photometer

THE DETERMINATION OF CALCIUM IN BIOLOGICAL

The use of flame photometers has greatly simplified and expedited the estimation of sodium and potassium. Calcium is one of the elements which it is possible to determine by flame photo-metry, but little advantage has been taken of this fact in biological work for a number of reasons. The concentration of calcium in extracellular
