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。

摘  要:
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.
