Moss is used as an important material in indoor landscaping as well as outdoor landscaping. Moss is vivid green during growth and excellent in ornamental value, but when temperature drops growth is easily stopped or browned and loses its ornamental value. It is necessary to select highly adaptable native moss at low temperature or light intensity such as indoors. On the other hand, in Korea, fine dust has become a serious social problem in recent years, and volatile organic substances generated by building materials for new houses are also seriously threatening people's health. Accordingly, there is a growing interest in developing plant materials that can remove fine dust or improve air quality. In this study, in order to introduce a basic imformation about moss plant, the growth response to low temperature and light intensity were investigated and ability of moss absorbing fine dust and cleaning air pollution evaluated. The results are followings.
1. Growth and regrowth responses to low temperatures of 9 native moss species
In the present experiment, for the purpose of classifying native mosses according to the growth response against low temperature, the temperature of a plant growth chamber was set to 15℃/5℃ (16/8h, day/night) or 5℃ (24h) for 8 weeks using 9 native moss species. Thereafter, the temperature of the plant growth chamber was set to 20℃, and then the changes of moss block area and the moss color were measured for 6 weeks. The changes of moss block size and moss color were measured using a Photoshop program. As a result, Etodon luridus, Brachythecium plumosum, and Hypnum plumaeforme showed a small decrease in moss block size at low temperature, and their recover were the fastest at 20℃. These three species among the mosses had higher green value at low temperature compared to other species, anthe green value increased very fast at 20℃. On the other hand, the Atrichum undulatum, Marchantia polymorpha, and Thuidium cymbifolium showed the lowest block size at low temperatures and the lowest recovery even at 20℃. Their green value also decreased largely at low temperature, and maintained low values in green color even at 20℃. These resuts showed that these 3 moss species are sensitive to low temperature. The remaining Myuroclada maximowiczii, Plagiomnium cuspidatum, and Hypnum erectiusculum were judged moderate to low temperature compared to other 6 kinds mosses.
2. Growth responses to low light intensity of 9 native moss species
In order to introduce native moss for indoor landscaping or interior decoration, it is necessary to select highly adaptable moss at low light intensity such as indoors. Nine native mosses were grown under light intensity of 25, 50, and 100umol·m-2·s-1, and the moss block area and moss color change were investigated for 8 weeks. As a result, 4 kinds of mosses such as Etodon luridus, Myuroclada maximowiczii, Brachythecium plumosum, and Plagiomnium cuspidatum showed continuous increase in moss area and green value for 8 weeks regardless of the light intensity. This suggested that the 4 mosses are able to be adaptable even under low light condition like indoor. On the contrary, Marchantia polymorpha, Thuidium cymbifolium, and Hypnum plumaeforme showed small increase in moss area and green value was much lower than other species, and it was suggested that those mosses were not suitable for indoor low light.
3. Effects of some native moss pants on the removal of fine dust, volatile organic compounds, and oher air compositions
Experiments were carried out to investigate the effects of mosses on the removal of particular matter (PM 10) and volatile organic compounds in indoor space and other air composition by using some native mosses (Plagiomnium cuspidatum, Myuroclada maximowiczii, Etodon luridus). As a result, it was found that the particular matter was removed effectively by the three mosses, and the removal efficiency of particular matter increased as the amount of mosses increased. The volatile organic compounds (VOC) were similar to the control and scindapsus at low amount of mosses (2 and 4 plates). However, the removal efficiency of VOC was remarkable at 6 plates of moss. On the other hand, when 0.2g of mosquito repellent was completely burned in the glass chamber, it was found that formaldehyde was 40 times more than the control and carbon monoxide 30 times more than the control. Removal effect of formaldehyde by moss plants was not observed. In conclusion, the moss plants showed excellent effect of removing particular matter and volatile organic compounds, and it is expected to be used for indoor decoration and landscape in order to improve indoor air quality in the future.
