METHOD: Both IFAS and Visual Examination CONDITIONS: Green House - 12h light METHOD NARR: One month after planting TPS, roots were washed clean and immersed in a suspension of C. sepedonicum for five minutes. Those plants that wfour weeks were stem inoculated with 100ul of cell suspension. Some accessions were also tuber inoculated. A thin slice was removed from the stem end of each tuber. Tubers were then soaked in bacterial suspension for fivere not made on symptomless plants. Plants were evaluated for up to 12 weeks. Following the final assessment, symptomless plants were IFAS tested. RESULTS NARR: IFAS results as based on a mean of 10 fields: 0 = No Cells, +/- 2+ = 11-20 cells, 3+ = 21-50 cells, 4+ = >50 cells. AUTHOR EXPLANATION: The differences between the two inoculation methods (tuber vs root) may account for the difference in apparent symptomless rates. The results in this study diies and this may be cause by differences in day length or total light energy.
