Descripción
This study was conducted to analyze removal efficiency of total volatile organic and physiological responses of climbing native plants <i>Ardisia pusilla</i> and <i>Ficus pumila</i>. The <i>Hedera helix </i>as a control, plants were investigated the total volatile organic compounds and their corresponding physiological responses with the maximum quantum yield of PSII (<i>F</i><sub>v</sub>/<i>F</i><sub>m</sub>)chlorophyll fluorescence, the vegetation index (the normalized difference vegetation index, NDVI; the simple ratio, SR; the carotenoid reflectance index 1, 2; CRI 1, 2) and physiological activity (the flavonoids and the phenolics). As a result, the removal amount of native plants tended to be lager than <i>Hedera helix</i> (2.973mgm<sup>-3</sup>h<sup>-1</sup>m<sup>-2</sup> leaf area) and<i> Ficus pumila </i>(4.481mgm<sup>-3</sup>h<sup>-1</sup>m<sup>-2</sup> leaf area) had more removal than <i>Ardisia pusilla</i> (3.786 mgm<sup>-3</sup>h<sup>-1</sup>m<sup>-2</sup> leaf area), significantly. The NDVI, SR, and CRI 1, 2 of <i>Ficus pumila </i>and <i>Hedera helix </i>decreased after 2 hours, but there was no difference before and after with pollutants in <i>Ardisia pusilla</i>. In addition, only <i>Ardisia pusilla </i>had the normal range of 0.78 to 0.84 with <i>F</i><sub>v</sub>/<i>F</i><sub>m</sub>. Through this result, it is judged <i>Ardisia pusilla </i>is normally metabolized in plants without negative effects when removing indoor pollutants. Additionally, <i>Ardisia pusilla </i>did not change about phenolic, but the flavonoids contents increased after 2 hours. The physiological activity of <i>Ficus pumila </i>increased from 4 hours and then dereased again at 6 hours. Therefore, the removal of total volatile organic compounds was effective in the <i>Ficus pumila</i>,<i> Ardisia pusilla</i>, <i>Hedera helix</i> order, but in the results of stress and physiological activity of plants after air purification, <i>Ardisia pusilla </i>maintained a normal range than other plants and increased antioxidants. It is considered to be highly useful as an air purification plant due to its low damage.
