Flow Cytometry DNA content histogram. Flow cytometry analysis of DNA fluorescence peaks (FL1A) from G0/G1 (2C) PI stained leaf nuclei from cultivated cardoon (M1), globe artichoke (M2) and P. sativum (pea) (M3). Pea was used as an internal standard and the peak was set at channel 400; M4 shows pea G2 nuclei (4C).
