Abstract

The present investigation was conducted during 2017-2018 to assess the air pollution tolerance index of indoor plants commonly grown in subtropical climate. The study was carried out to determine the air pollution tolerance of indoor plants and use in urban indoor landscaping. In this study,30 flowering and foliage indoor plants were selected and the air pollution tolerance index (APTI) was assessed in which various bio-chemical parameters such as total chlorophyll content, leaf extract pH, relative water content and ascorbic acid content were estimated using CRD design. Maximum APTI value was found in Aglaonema modestum (9.18) followed by Scindapsus aureus (9.16), Chlorophytum comosum (9.14), Nephrolepis exaltata (9.054) and Kalanchoe blossfeldiana (8.967). Results concluded that Aglaonema modestum, Scindapsus aureus, Chlorophytum comosum, Nephrolepis exaltata and Kalanchoe blossfeldiana were found best to tolerate air pollution on the basis of APTI and these plants can be used in ind

Conclusion

From the present findings, Aglaonema modestum, Scindapsus aureus, Chlorophytum comosum, Nephrolepis exaltata and Kalanchoe blossfeldiana were found best indoor plants to tolerate air pollution and can be recommended for urban area having high pollution levels.
