Effect of Dust Types on the Eco-Physiological Response of Three Tree Species Seedlings: Eucalyptus camaldulensis, Conocarpus erectus and Bombax ceiba

Dust is the collection of fine particles solid matter, and it a major issue atmospheric pollution. are becoming pollutants urban environment due to hyperbolic manufacturing automobile These not only hazardous for human beings, but they also affect tree growth, particularly in environments. This study was designed examine changes morphological physiological traits three species seedlings (Eucalyptus camaldulensis, Conocarpus erectus, Bombax ceiba) response different dust types. In pot experiment under controlled conditions, three-month-old selected trees were subjected four treatments dust: T1 = controlled; T2 wood dust; T3 soil T4 carbon dust. During whole experiment, 10 g/plant/dose applied 8 doses with one-week interval. The results depicted that growth maximum (control) minimum (carbon dust). our findings, B. ceiba performed better same levels pollution as compared other two species. proved be most tolerant by efficiently demolishing oxidative bursts triggering SOD, POD, CAT types conditions. Stomatal conductance, photosynthetic rate, transpiration rate negatively influenced all applications. Based on among these species, recommended polluted areas followed E. camaldulensis erectus their performance efficient dust-foraging potential.
