• As well known in several plants, low temperature treatment induces at some definite segments of mitotic chromosomes certain reduction in their diameter and stainability. In the case of meiotic chromosomes, however, such an effect of cold treatment has not ascertained as yet.The present study revealed certain differentiation between eu- and heterochromatic segments to occur in MI chromosomes of Paris verticillata, which was kept at low temperature, O°C, during its meiosis; the euchromatic segments were remarkably shortened, the major coils being increased in diameter, while the heterochromatic segments were elongated, the major coils being rednced in diameter.
