Pollen Mother Cells of Zingiber, an Outstanding Material for the Study of Karyokinetic Spindle

Abstract

Well-defined spindle figures are observable in the pollen mother cells of Zingiber Mioga under ordinary light as well as polarized light microscopes. The spindle is characterized by its large size and sharply pointed poles and also the presence of a spindle membrane, the chromosomal fibers, the distribution of spindle unit fibrils, and their independency in the cell are obviously demonstrable. These excellent characters in the meiotic cells of Zingiber Mioga are available to analyze the entity of the spindle body morphologically and biochemically in future.
