Estimation of nuclear DNA amount (genome size). The histograms of PI fluorescence were obtained by flow cytometric analysis. Glycine max Williams 82 served as internal standard for Populus szechuanica (A) and Carrierea calycina (B), while Zea mays L. B73 served as internal standard for Idesia polycarpa (C) and Dianyuea turbinate (D). Small peaks at about twice the DNA content of the marker G1 peak represent the cells in G2 phase
