Abstract
We used chlorotetracycline fluorescence, alizarin staining and potassi um pyroantimonate methods, as well as X-ray microanalysis, to demonstr ate the differential localization of Ca2+ during pollen maturation. Le vel 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.
