Uptake and loss of ^<45>Ca^<2+>, ^<22>Na^+, and H_2^<32>PO_4^- by tea pollen tubes precultured for 20 h were studied to clarify the pattern of ion uptake by pollen tubes. uptake of ^<45>Ca^<2+>, ^<22>Na^+, and H_2^<32>PO_4^- which increased with the incubation time became maximum after 5, 1, and 8 h for ^<45>Ca^2+>, ^<22>Na^+, and H_2^<32>PO_4^-, respectively. After the maximum uptake, the ions were excreted. The ^<45>Ca^<2+> uptake was highest at pH 7.5 and the ^<22>Na^+ uptake increased as the solution pH increased up to 7.8. the H_2^<32>PO_4^- uptake was greatest at pH 5.5. the uptake of ^<45>Ca^<2+> and H_2^<32>PO_4^- was maximum at 25℃. The uptake of H_2^<32>PO_4^- was more affected by the temperature than that of ^<45>Ca^<2+>. Metabolic inhibitors [2,4-dinitrophenol(DNP), ouabain, chloramphenicol, and cycloheximide] suppressed the uptake of ^<45>Ca^<2+> and H_2^<32>PO_4^-, but had no effect on the uptake of ^<22>Na^+. The ^<22>Na^+ uptake was reduced by the addition of Ca^<2+> but not K^+. the loss of ^<45>Ca^<2+> from the pollen tubes which showed three successive phases, was prevented by the addition of DNP. The pattern of ion uptake by the tea pollen tubes showed some similarities with that of intact plants, excised roots and disks of storage tissues.
