摘要：

The cultivars or experimental lines of Pisum sativum were analyzed cytophotometrically for nuclear DNA content of early prophases after ethanol-acetic acid fixation. Wide variability was found (from 3.93 to 5.07pg per haploid nucleus). This result was confirmed by the cytophotometric analysis of interphase nuclei isolated from leaf tissues fixed in formalin. Analysis of interphase nuclei at different thresholds of optical density showed that certain chromatin fractions are involved in the variations. © 1990 Springer-Verlag.
