Use of electron microprobe x-ray analysis for determination of low calcium concentrations across leaves deficient in calcium.
Commun. Soil Sci. Plant Anal. 25 , 191, (1994) An electron microprobe with wavelength-dispersive x-ray spectrometry (WDS) was found to be useful for the determination of Ca concentrations in leaf tissue deficient in Ca. WDS effectively detected Ca concentrations as low as 0.2 mg/g dry wt in the presence o... |
