AbstractA method for reducing cytochimerism and inducing homogeneous tetraploids in Haplopappus gracilis was developed in which masses of shoot primordia treated with 0.5mg/ml of colcemid for 3 days were cut into small meristematic domes. All of the shoot primordia sampled just after the colcemid treatment were cytochimeras that were mixoploids of 2x, 4x and 8x cells. However, when they were allowed...
