UV-B辐射增强对冬小麦生长发育及产量的影响
Effects of enhanced UV-B radiation on growth,development and yield of winter wheat
-
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。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.
