Fig. 2. Flow histogram of Soybean PI accession 266085 co-chopped and analyzed with A. plameri as an internal standard. The mean of the G1/G0 peak of the Soybean line was 338.6 and the mean of the internal standard was 117.4. The relative DNA amount of the experimental standard sample was 2.884 times the internal standard.
