A Dissection of the Chromosomes in the Pollen Mother Cells of Tradescantia Virginica L

CHROMOSOME STRUCTURE AND ITS RELATION TO THE CHROMOSOME CYCLE: I. SOMATIC MITOSES IN TRADESCANTIA PILOSA

“…That the latter was peripherally disposed was verified by the living chromosome dissected from the pollen mother cells of this plant by Chambers and Sands (1923), who described an elastic cylinder, possessing a cortex which differs markedly in refractive index from the central core. That the latter was peripherally disposed was verified by the living chromosome dissected from the pollen mother cells of this plant by Chambers and Sands (1923), who described an elastic cylinder, possessing a cortex which differs markedly in refractive index from the central core.…”

Chromosome Structure and Its Relation to the Chromosome Cycle I. Somatic Mitoses in Tradescantia pilosa

“…Sands' aceto-carmine preparations were valuable in demonstrating the achromatic material as the substance in which the chromatin was imbedded. That the latter was peripherally disposed was verified by the living chromosome dissected from the pollen mother cells of this plant by Chambers and Sands (1923), who described an elastic cylinder, possessing a cortex which differs markedly in refractive index from the central core.…”

The Mechanism of Mitosis Based on Studies of the Submicroscopic Structure and of the Living State of the <i>Tradescantia</i> Cell

“…In reality, by micrurgical treatments the writer has pointed out that the atractoplasm, in meta and anaphase, shows rather a fluid nature (Wada 1935 p. 386) and is not so viscous nor in gel state as is generally believed (cf. Chambers and Sands 1923). It is, however, to be noted that its viscosity increases suddenly in the beginning of the telophase.…”
