Abstract: This research work aimed at the investigating wound response on a lesion of tomato fruits during storage and shelf life. The research determine the most effective post-harvest treatment on tomato fruits subjected to wounding and infected with Grey Mould (Botrytis cinerea). The trial was conducted in series of four experiments, a single low and high concentrations, interaction of 30 mM Ca with low and high concentrations. Tomatoes treated with 10% ethanol solutions were included as controls in each experiment. The fruits were inoculated with Botrytis cinerea spores 10 minutes after the treatments and incubated at 10℃±1℃ and 85-90% RH for 14days in every successions. The result revealed that among the single treatments 30 mM SA and 30 mM Ca had the greater inhibition effect of Botrytis cinerea on the tomato fruits considering their mean lesion diameter at (d14). However, the combination of 30 mM SA and 30 mM Ca resulted to a significant treatment that inhibit the effect of the fungus. Hence this research suggests a combination of 30 mM SA with 30 mM Ca in suppressing the spread of Botrytis cinerea in tomato fruits. From the high concentration treatment the result show that the levels of different treatment are associated with the lesion size of the disease spread, because the P-value (0.0357) is the significant level of (0.05), hence the different treatments are statistically significant. The incubation days is also associated with the lesion size diameter at P-value (0.0411). Equally there is significant difference statistically at different measurement days of incubation in respect to lesion size diameter.
