| Abstract: | We used chlorotetracycline fluorescence, alizarin staining and potassium pyroantimonate methods, as well as X-ray microanalysis,
to demonstrate the differential localization of Ca2+ during pollen maturation. Level of loosely-bound Ca2+ ions was higher
in the generative cell than in the vegetative cell of the mature pollen grain which is one of the symptoms of metabolic differentiation
of the two sister cells.
