| 摘 要： | 云南元阳梯田稻田被认为是持续稳定稻田生态系统的典型代表.在元阳梯田原生环境中,通过大田试验,研究UV-B辐射(0、2.5、5.0、7.5 kJ·m-2)增强对元阳梯田地方水稻白脚老粳和月亮谷的茎与叶硅含量、叶类黄酮和总酚含量的影响.结果表明:(1)UV-B辐射处理下,白脚老粳拔节期茎和叶的硅含量、月亮谷抽穗期茎的硅含量、拔节期和抽穗期叶的硅含量均显著增加.(2)UV-B辐射导致白脚老粳(除2.5 kJ·m-2)和月亮谷抽穗期叶的类黄酮含量显著增加.(3)UV-B辐射导致白脚老粳分蘖期(除2.5 kJ·m-2)、拔节期(除2.5 kJ ·m-2)和抽穗期叶的总酚含量均显著增加；月亮谷分蘖期和抽穗期(除2.5 kJ· m-2)叶的总酚含量显著增加.(4)2个水稻品种叶的硅含量与类黄酮、总酚含量均呈极显著正相关.总体来看,UV-B辐射增强促进白脚老粳茎与叶硅含量、叶类黄酮和总酚含量的增加,其增加百分率高于月亮谷,表明白脚老粳和月亮谷对UV-B辐射的抗性有所不同.
