| Sumario: | [EN] Secondary metabolites in plants are organic molecules that fulfil non-essential but necessary functions. Among these, phenolic compounds or phenylpropanoids play a fundamental role. They are biochemically modulated and synthesised via two principal pathways, the shikimic acid pathway and, to a lesser extent, the malonic acid pathway. The enzyme Phenylalanine Ammonium Lyase (PAL) is found in the shikimic acid pathway and is responsible for naturally synthesising polyphenols, phytoalexins and phytotoxins in plants. The results obtained by the Spanish National Research Council (CSIC) show how applying Brotomax® to a healthy grapevine plantation can increase the enzymatic activity of PAL in the leaves, with statistically significant differences compared to untreated or control plants. Better results are also obtained when the elicitor is applied via irrigation as opposed to foliar application. Brotomax® does not directly provide the plant with phenolic compounds, instead it influences the biochemical modulation of these compounds and lets nature regulate and balance their action. |
