A Study of Pollen Grain Mitosis in Xanthisma texanum DC
Abstract
Berger and Witkus (1954) noticed that in the composite plant, Xanthisma texanum DC., there was a difference in the chromosome number between the root and the shoot tissue in a number of plants. In some plants 8 chromosomes were present throughout the plant, while in others there were 8 chromosomes in the root and 10 chromosomes in the shoot. These two strains proved to be two different cytological types. However, morphologically they were identical. The tapetal cells of a 5 bivalent plant showed a diploid chromosome number of 10 and the non-germinal epithelium of the anthers also had 10 chromosomes.
