| 摘 要： | 对比分析了南京地区和宁夏地区UV—B辐射增强对小麦的影响。结果表明，低海拔地区小麦比中高海拔地区小麦对UV—B辐射增强敏感，南京地区UV—B辐射增强抑制小麦生长、减小LAI，抑制生物学产量和经济学产量；宁夏地区UV—B辐射增强抑制株高，抑制生殖生长时期LAI和干物质累积，增加营养生长时期LAI和干物质累积，使经济学产量及其构成因素减少。 |
| 关 键 词： | 南京市 宁夏地区 UV—B辐射 小麦 |

| Abstract: | The effects of enhanced UV -B radiation on wheat in Nanjing and Ningxia we re compared.The results indicated t hat the wheat in lower altitudes showed more sensitive to UV -B radiation than that in middle and higher altitudes.In Nanjing,the growth,leaf area index(LAI ),the biological yield and economic y ield of wheat all decreased under enhanced UV -B radiation conditions In Ningxia,however,the plant height,the LAI and the accumulation of dry ma tter of wheat in reproductive growth stage were re-strained,while the LAI and the accum ulation of dry matter of wheat in vegetative growth stage increased and th e economic yield and its constituents reduced. |
| Keywords: | wheat UV -B radiation growth pla nt shape yield constituents |
