Optical absorption spectra of germinated seedlings from seeds exposed to vehicle polluting gases

摘要: High pollution rates in large cities have had a negative impact on human, animal and plant health. In the case of plants, several techniques been used to analyze physical physiological parameters their seedlings seed germination process, under different environmental conditions. This study proposed evaluation from corn, lentils bean seeds, exposed polluting gases (CO, CO2) through container system vehicle engine, during times (0, 20, 40, 60 80 min). The after exposition pollutant gases, were planted, optical absorption spectra each seedling obtained by photoacoustic spectroscopy. wavelength range 250 750 nm. demonstrated significant statistical differences 290 300 nm (corresponding mainly flavonoids) also 650 680 nm chlorophylls). addition, changes parameters, evaluated.
