Cause of ring and round spots of tomato fruits found in fields and greenhouses was investigated. Botrytis cinerea was isolated from about twenty percent of these spots. Young fruit inoculated artificially with spore suspension of Botrytis cinerea formed same spots as natural symptoms. This results showed that these symptoms were same as 'ghost-spot' reported by W.H. Read and other researchers. The spots were classified into three types as white spot, green spot and necrotic spot. The white spots having halo were produced mainly on shoulder and lateral parts of fruit which was exposed to sunlight always and the green spots were produced on under side of fruit. The necrotic spots appeared on same position as white spot, but they were very few. Histological studies indicated that the halo of white spot was ring-shaped tissue formed by abnormal multiplication and swelling of epidermal cells (Plate II,4 . 5). The tissue of green spot was formed by ten or more layers of thick walled epidermal cells produced by abnormal cell division. ecrotic spot was formed by complete callus tissue produced arround the invasion point of B. cinerea. Results of the observations made on incidence of ghost-spot in a greenhouse and a field showed that abundant spores of B. cinerea producing in near place of toma to and suitable condition for infection were necessary for occurrence of ghost-spot |
