Scanning Electron Microscope Examination of Flower Bud Differentiation in Sour Cherry1

open access: yesJournal of the American Society for Horticultural Science, 1981
Abstract Axillary buds on ‘Montmorency’ sour cherry ( Prunus cerasus L.) shoots were examined by scanning electron microscopy. On June 10, 4 weeks after anthesis, a doming of the apex signified the initial change from the vegetative to the reproductive stage.
