CELL SIZE, NUCLEAR SIZE AND DNA CONTENT RELATIONSHIPS IN GOSSYPIUM

Abstract
Cell and nuclear volumes were determined for 17 species and plant types in the genus Gossypium. All species and types, except one, showed a significant positive association between nuclear and cell volume. The overall species r-value (0.694) for cell and nuclear volume is highly significant and positive. For the 17 plant forms, the r-values for association of DNA content and nuclear volume and for association of DNA content and cell volume are 0.625 and 0.655, respectively, and both are highly significant.
