| Summary: | In our researches we studied the influence of exogenous acetylsalicylic acid (ASA) in the plant response to abiotic and biotic stress. Salt stress, an abiotic stress, determine modification of some biochemical indicators, like, antioxidant enzymes, proline (amino acid accumulate in higher plants under salinity stress) content, assimilatory pigment content. Pre-treatment of sunflower seeds with ASA may cause a low level of oxidative stress, improving the antioxidative capacity of the plants. Acetylsalicylic acid can increase the plant tolerance to salt stress induced in our experiment by 150 mM NaCI treatments. Moreover we studied the role of ASA in sunflower resistance, its antifungal effect against fungal pathogens (Botrytis cinerea and Sclerotica sclerotiorum), which has significant influence on the level and quality of the production of this plant. |
