Outline of Final Research Achievements

To develop the screening system on peach bacterial leaf spot resistance, measurements of the delayed emission of biophoton were carried out. Turns out that delayed emission of peach leaves affected by bacteria inoculation tended to decrease, compared to the non-inoculation ones, but varieties vary the pattern varied according to varieties. Decrease pattern of ‘Cimaritta ' was delayed and not clear. On the other hand, ‘ Mochizuki' showed very rapid decrease just after inoculation. Thus, these results suggest that complexed physiological responses are involved in the occurrences of resistance. And these results suggest that this method is useful for development of screening system on bacterial leaf spot disease.
