| Abstract | ||||
| Indoor plants play an important role in purification the indoor air pollutants. Therefore, the main objective of this investigation was to increase the resistance of areca palm plants to the excessive concentrations of air gaseous pollutants. The present study was carried out in plastic chambers (80cm length×80cm width×100cm height) for exposing plants to formaldehyde or ammonia gasses after spraying with non-enzymatic antioxidants (glutathione and bilirubin at 300mg L-1 and 600mg L-1). Plants exposed to ammonia were highest in the number of dead leaves and leave injury percentage comparing with the plants exposed to formaldehyde. Plants treated with glutathione at 600 mg L-1 or bilirubin at 300mg L-1 before exposure to formaldehyde gas were not injured leaves, as well as, increased in dry weight and chlorophyll concentration compared with the plants exposed to formaldehyde gas without spraying with antioxidants. Spraying plants with bilirubin at 300mg L-1 before exposure to formaldehyde were increased in total carotenoids as well as increased guaiacol peroxidase (GOPX) and catalase (CAT) activities under formaldehyde whereas it increased the activeties of ascorbate peroxidase (APX) and polyphenol oxidase (PPO) under ammonia. Also, plants treated with bilirubin or glutathione increased in stomata density and pore length under formaldehyde gas. In conclusion, spraying areca plants with bilirubin at 300 mg L-1 enhanced the plant resistance to the formaldehyde and ammonia air pollutants followed by glutathione treatments. Areca palm plants were higher sensitivity to ammonia gas than with formaldehyde gas. | ||||
