| 摘 要： | 利用OTC 1型开顶式气室对冬小麦进行不同O3 浓度处理的试验研究。结果表明 ,O3 浓度增加 ,冬小麦发育期表现为开花前期有所延迟 ,开花后期的各发育期明显提前 ,生育期缩短 ,植株矮化 ,干物质累积量明显下降。无论是长时期通气处理还是阶段性通气处理 ,产量均明显降低 |

| Abstract: | The effects of under different concentrations of ozone on winter wheat inside the open top chambers (OTC 1) have been studied.The experimental result indicates that there are obvious variations on the wheat's growth when ozone concentration was increased.The variations are:(1)phenological phase of the winter wheat was delayed before flowering and brought forward after flowering,growth and development phase will be shorten.(2)The plant height will be short.(3)Regardless of long time ventilation or short time ventilation treatments,the yields of winter wheat will be distinctly deceased under ozone exposure. |
