| 中文摘要: |
| 自然光照条件下，以酿酒葡萄“赤霞珠”（Cabernet Sauvignon）为材料，研究了UV-B辐射增强下葡萄叶片光合特性与叶龄的关系。结果表明：低辐射(T1)处理下，葡萄叶片的光合能力随着叶龄增加而显著增加，与对照（CK）相比达极显著水平；高辐射(T2)处理下，葡萄叶片的光合能力随着叶龄增加而降低，但与对照（CK）相比差异不显著。这说明葡萄对UV-B辐射增强有较强的适应性，适当增加UV-B辐射剂量对葡萄叶片Pn具有一定的促进作用。 |
| 英文摘要: |
| Under natural sunlight conditions, the relationship between photosynthesis and leaf ages of grapevine(Cabernet Sauvignon) under enhanced ultraviolet-B radiation was studied. The results showed that: Under the treatments of enhanced lower UV-B radiation, the photosynthesis of grapevine obviously increased with leaf ages, and under the treatments of enhanced higher UV-B radiation, the grapevine photosynthesis decreased, but it was not significant compared to that of the control. It suggested that the grapevine have strong adaptability to UV-B radiation, and appropriate enhanced UV-B radiation could increase the photosynthesis of grapevine leaves. |
