摘要

Plasma membrane (PM) Ca~2+-ATPase activity in poplar apical bud meristematic cells during short-day (SD)-induced dor- many development was exmined by a cerium precipitation EM-cytochemical method. Ca~2+-ATPase activity, indicated by The status of cerium phosphate precipitated grains, was local- Ized mainly on the interior face (cytoplasmic side) of the PM When plants were grown under long days and reached a deep Dormancy. A few reaction products were also observed on the Nuclear envelope.
