Eliciators increase gas exchanges and induce the Zea mays antioxidant system

The plant elicitors use as an agricultural input is limited and few studies show their influence on physiological responses. However, its can induce broad-spectrum long-lasting resistance in plants by inducing defense systems, primary secondary metabolism. the aim of this study was to evaluate gas exchange (gs, A, E, Ci, WUE, iWUE iCE) enzymatic antioxidant system (POD, PPO PAL) Z. mays under application. experiment carried out a completely randomized design with seven treatments: control (sterilized distilled water); Rocksil® (3 g L-1); Poagrim® Bion® (0.4 Agrosilicon Plus® Ecolife® mL Thiabendazol® (1 L-1), four repetitions three per repetition. Gas (net photosynthesis [A], stomatal conductance [gs], internal carbon concentration [Ci], transpiration rate [E], instantaneous water efficiency [WUE= A/E], intrinsic [iWUE= A/gs], carboxylation [iCE= A/Ci], activity (peroxidase [POX], polyphenol oxidase [PPO], phenylalanine ammonia-lyase [PAL]) were evaluated at 40 45 days after sowing. Gs, iCE peroxidase increased whose seeds soaked Thiabendazol®. reduced from Ecolife®. Zea L.
