Study Name: Resistance to Bacterial Stem Rot. Experiment Type: Greenhouse GREENHOUSE Study Year: 1987 Year started: 06/02/1987 Year ended: 02/05/1988. Three to four week old seedlings were inoculated by crushing the leaf and petiole with tweezers and spraying with five different concentrations of bacterial suspensions. The bacterial levels of E. carotovora subsp. carotovora were 105, 106, 107, 108, and 109. Plants were visually scored by a resistance index (0-4) and percentiles were based on the average of the five trials.
