The Effects of Ozone on Respiration of the Plants Fuchsia hybrida Voss. and Vicia faba L.
臭氧对倒挂金钟和蚕豆呼吸作用的影响

The plants, Fuchsia kybrida Voss. and Vicia faba L., were fumigated with ozone at different concentrations. It was observed that the lower level of ozone would stimulate respiration. Such effect did not easily disappear for a long time after stopping fumigation. However, the higher concentration of ozone inhibited respiration. If the injury caused by ozone was not so severe that the plant respiration could recover to normal.It is suggested that there might be two kinds of mechanism which control the rise and fall of respiration. These two actions compensate and adjust each other under the conditions of controlling ozone doses, resulting in various phenomena of respiration intensity, such as increasing, decreasing or unremarkable changes, recoverable or irrecoverable, etc.
