Carbon dioxide is a gas contributing greatly to the greenhouse effect, due to the high volume of emissions originated in the power stations that use fossil fuels. The fulfilment of the Kyoto protocol involves the development of technologies to decrease the CO2 emissions during their generation or later, through capturing (sequestration), transport and storage and valuation technologies. The plants are sinks for CO2 and can be a good means of incorporating the combustion gases, whose composition, besides CO2, may also have toxic gases, such as sulphur dioxide (SO2). A work has been done to evaluate how the supply of gases coming from industry may affect greenhouse horticultural crops. The study has been developed inside a growth chamber, for three different horticultural species (cucumber, tomato and pepper) with plants at two different stages (seedlings and adult plants). The experiments were developed in a controlled environment for radiation, temperature and humidity. The variable was SO2 concentration with three different levels: 0, 0.18 and 0.56 ppm. The results show that the SO2 concentration levels tested significantly decreased the growth of the plants (dry matter) in relation to the reference (0 ppm of SO2) level for the three crops (cucumber, tomato and pepper). Similar results occurred with the leaf formation rate and the stem growth rate.
