No results found.This study was conducted to analyze removal efficiency of total volatile organic and physiological responses of climbing native plants Ardisia pusilla and Ficus pumila. The Hedera helix as a control, plants were investigated the total volatile organic compounds and their corresponding physiological responses with the maximum quantum yield of PSII (Fv/Fm)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 Hedera helix (2.973mgm-3h-1m-2 leaf area) and Ficus pumila (4.481mgm-3h-1m-2 leaf area) had more removal than Ardisia pusilla (3.786 mgm-3h-1m-2 leaf area), significantly. The NDVI, SR, and CRI 1, 2 of Ficus pumila and Hedera helix decreased after 2 hours, but there was no difference before and after with pollutants in Ardisia pusilla. In addition, only Ardisia pusilla had the normal range of 0.78 to 0.84 with Fv/Fm. Through this result, it is judged Ardisia pusilla is normally metabolized in plants without negative effects when removing indoor pollutants. Additionally, Ardisia pusilla did not change about phenolic, but the flavonoids contents increased after 2 hours. The physiological activity of Ficus pumila increased from 4 hours and then dereased again at 6 hours. Therefore, the removal of total volatile organic compounds was effective in the Ficus pumila, Ardisia pusilla, Hedera helix order, but in the results of stress and physiological activity of plants after air purification, Ardisia pusilla 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. Keywords: Human health and well-being, Climate change, Covid-19, Research, Landscape management ID: 3622900
