Abstract

The aim of this study was to examine the effect of VOC exposure from cigarette smoke on the plant growth regulator (PGR) patterns consisting of Indole Acetic Acid (IAA), Abscisic Acid (ABA), Ethylene, Salicylic Acid (SA) and Jasmonic Acid (JA) so that later it could be screened for some ornamental indoor plants that could be used as a phytoremediator agent. The ornamental plants used are Drimiopsis kirkii, Epipremnum pinnatum, Sanseviera trifasciata, Peperomia obtusifolia variegata and Dieffenbachia seguine. Exposure to plants with cigarette smoke containing formaldehyde as much as 0.1 ppm for 5.5 months then the content of the PGR was observed. The results showed that of the five ornamental plants used, there were two expression patterns of PGR. In D. kirkii and P. obtusiifolia-variegata there has been an increase in IAA, while 3 other species have decreased. Exposure to cigarette smoke decreases ABA in all five species while Ethylene increases. The most interesting discussed in this research is the increase in IAA in D. kirkii was not followed by changes in the expression of SA and JA.
