Abstract
This study was showed into the pollen development with in vivo by bud size and genotype. Microspores of buds from 2.0 mm to 2.5 mm of all genotypes were composed of mainly tetrad cells and early uninucleate stage cells. Microspores derived from buds of 2.5-3.0 mm were exposed cells of early uninucleate, middle uninucleate, and late uninucleate. Microspores from buds of 3.0-3.5 mm contained mostly late uninucleate stage cells and showed some early binucleate stage cells. Microspores of buds with 3.5-4.0 mm in length were composed of mainly binucleate stage cells and decreased late uninucleate stage cells. Microspore with more than 4.0 mm were entered into binucleate stage cells of divided generative nucleus and vegetative nucleus. In 'Tamlayuchae', microspores derived from buds of 3.5-4.0 mm were observed cells of late uninucleate stage and early binucleate stage because of late microspore development. In MS-maintainer, the spring type, microspore derived from buds of 2.5-3.0 mm were observed tetrad stage cells.
