Changes of the Intracellular Reducing Intensity in the Pollen Mother Cells During Meiosis of the Young Lilium Anthers

Abstract

1. The total reducing power in various tissues of Lilium anthers, especially of the sporogenous tissue (the sporogenous and the pollen mother cells), was determined by means of the indicator method during the development of the sporogenous tissue.
2. The reducing power of the sporogenous and tapetal tissues increases from premeiosis to meiosis remarkably, while in other tissues no such remarkable increase is seen.
3. The redox-potentials of N. V. E. Grübler were determined by using Michaelis' vessel with the changes of its colours.
