Resumen : | Cell free extract from a pathogenic strain of Pseudomonas sp (PB11) able to cause bacterial speck was prompted for protection against that disease in tomato plants (Solana lycopersicum) under greenhouse conditions. This extract was applied to one month old tomato plants. After four days, plants were inoculated with Pseudomonas sp PB11. Infection severity was determined by counting the number of necrotic lesions present in each plant and it were expressed as damage percentage. The extract led to a significantly infection reduction of more than 60% (p<0.05). The protection effect was observed on the fifth day after inoculation and it was maintained for the next 30 days. This study shows the potential of PB11 cell free extract to induce a defence response in tomato plants to Pseudomonas sp (PB11) under greenhouse conditions. |
