| 中文摘要 |
| 在较低浓度臭氧作用下,植物的呼吸受到刺激,在一定时间内,这种影响不易消除;在高浓度臭氧作用下,植物的呼吸受到抑制,在一定时间内保持相对稳定,以后逐渐恢复,分析讨论了臭氧影响植物呼吸变化的机理。 |
| 英文摘要 |
| 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. |
