Hanging sticky traps around the area can capture pests, aiding in their identification and removal. Standing in the Hydroponic system and waving our arms around to repel flying insects from landing on plants. Putting magnets in the soil to disturb the electric conductivity of soil, confusing pests and preventing them from reaching plant roots. Playing loud music to prevent pests from entering the system. 2 / 4 How are Mycorrhizae fungi beneficial to plants? They can enhance plant resilience by forming a symbiotic bond with the plant and improving nutrient uptake via extended root system. They release aromatic compounds which ward off insects that suck on plant sap. If they are in a symbiotic relationship with mosses, they can protect plants from getting eaten by larger herbivores. They are not beneficial at all. 3 / 4 What are some natural defence mechanisms used by plants in hydroponic system? (More than one is correct). Thickening cell walls, producing protective chemicals, and activating stress-response genes. Induction of reproductive growth. Forming symbiosis with (added) beneficial microorganisms, enhancing plant resilience by improving nutrient uptake and stress tolerance. Using as much energy as possible to keep thriving in stressful conditions. 4 / 4 Which are the most common plant stressors in the hydroponic plant production? Extreme temperatures, high salinity, too much or too little water, heavy metals, and UV radiation. Bacteria, fungi, and pest larvae in the soil. Too much water, high sand content, and opening of leaf stomata during the day. Genetic defects. Your score isThe average score is 0% 0% Restart quiz
