【Abstract】 1. A study has been made of the intercellular migrating chromatin substance in the cells of various stages in the developmental pollen mother cells of the anthers of 6 families 10 genera of Angiosperms. 2. According to our observations and experiments it has been shown that this process is neither induced by the fixation, treatment, mechanical injury, nor is it due to a virus or other infections. This phenomenon is considered to be normal and inherent cell activity because of their wide distribution and frequent occurence under many environments. 3. In our preparations the migration of the chromatin substance occurs most frequently at the time of premeiotic stage or early prophase. 4. It seems to us that the phenomenon of this process is quite the same as in Lilium sutchunense Franch published in 1955. 5. Such phenomenon is not only limited to the sporogeneous tissue but also in the somatic tissues and seems to show one of the physiological characters of cell reproduction. 6. It is suggested that the migrating chromatin substance may be correlated with cell growth and cell reproduction.更多还原
