| 摘 要： | 为研究辐射减弱和O3胁迫对作物的影响,利用改进的开顶式气室(OTC)和遮荫网,开展了辐射减弱和O3胁迫的大田试验研究.实验设置4种处理:CK为野外大田组,T1为40％遮荫,T2为100 nL/LO3,T3为遮荫40％和100 nL/LO3的复合组.结果表明:T1和T3组冬小麦的生育期延长且推迟,T3组株高无明显变化；T2组株高降低,生育期缩短；单株干物质重均降低,T3降幅最大；各组灌浆速率均降低,T3组降幅最大；T1和T3产量、千粒重、穗数、穗粒数和穗重显著降低,T2组穗数无明显改变.由此可见,复合对小麦生长的影响较接近40％遮荫；粒重降低主要是因为灌浆速率的降低,灌浆时间的影响较小；产量的降低主要是千粒重、穗数、穗重的降低,降幅最大,但小于两因子单独累加. |
