From compartmental analysis of radioisotope elution measurements, concentrations and fluxes of Ca 2+ were estimated for cortical cells in root segments of onion, Allium cepa L., relative to a complete nutrient solution containing 1 mM Ca 2+. Five compartments for Ca 2+ in the cortex were revealed. T
From compartmental analysis of radioisotope elution measurements, concentrations and fluxes of Mg a+ were estimated for cortical cells in root segments of onion, Allium cepa L., relative to a complete nutrient solution containing 0.25 mM Mg a+.

Onion guard cells, in contrast to those of Vicia and Pisum, do not require an alkaline treatment in order to fluoresce. Fluorescing compounds of Allium cepa L. were characterized using in-vivo microspectrophotometry; furthermore, invitro chemical analysis for epidermal tissue, intact guard and epide
