Analysis of the Chlorophyll Fluorescence Characteristics and Tolerance Ability of Taiwan Protophyte with Ozone Gas Exposure

Abstract

Plants could make the environment beauty and improve air quality. But the plants need adapt to the growing environment. In the industrial area or cities, ozone (O3) is a common pollutant; it could hurt human health and hinder the plants growth . This research used a custom-made fumigation equipment to evaluate the tolerance ability of 7 species of Taiwan protophyte with 200, 400 and 800 ppb O3gas exposure. The results of this research showed that among all tested trees,Aglaia formosanaandCerbera manghashad the strongest tolerance to O3and then theMillettia pinnataandPalaquium formosanum,Nageia nagi,Terminalia catappain series, theTournefortia argenteawas the least.
