| 摘 要： | 研究了大田栽培条件下紫外辐射增强对冬小麦孕穗、抽穗、开花、灌浆、结实以及产量的影响。结果表明,UV B辐射增强使小麦植株矮化,叶面积减小,穗重、茎重、叶重减小,灌浆速度变慢,灌浆不充实,此外,UV B辐射增强还使花粉败育率增大。 |
| 关 键 词： | UVB辐射 冬小麦 生长 发育 产量 |

| Abstract: | Effects of enhanced ultraviolet radiation(UV-B radiation,broad band with 280 to 400 nm)on winter wheat were investigated.The results indicated that enhanced UV-B radiation made the plant shorter,leaves smaller,spikes,stalks and leave lighter,the speed of milking slower and grains less plump,thus affecting the yield of the plant. |
| Keywords: | UV-B radiation winter wheat growth development yield |
