Summary Using the fluorescent calcium probe Quin-2, we could demonstrate a tip-to-base gradient of free calcium within growing pollen tubes ofLilium longiflorum. This result shows that it is possible to visualize calcium ions using Quin-2 in plant cells which are surrounded by a cell wall and that the calcium gradients demonstrated by CTC fluorescence (indicating membrane-bound calcium) and PIXE (showing total calcium) is paralleled by a gradient of free calcium in pollen tubes.
