摘要
[目的]阐明土壤干旱对葡萄果实发育过程中黄烷醇类多酚时空积累的影响。[方法]以酿酒葡萄赤霞珠(Vitis vinifera L.cv.‘Cabernet Sauvignon’)果实为试材,采用避雨棚和断根沟措施,人工模拟土壤干旱,初步研究了土壤干旱对葡萄果实中黄烷醇类多酚时空积累的作用。[结果]土壤干旱并未改变葡萄果实黄烷醇类多酚的空间积累模式,果梗含量最高,种子、果皮次之,果肉最低。在果实发育过程中,土壤干旱明显促进果肉和种子中黄烷醇类多酚积累,但对果梗和果皮作用不明显。[结论]土壤干旱并不改变葡萄果实发育过程中黄烷醇类多酚的时空积累规律,但能促进果实,特别是果肉和种子中黄烷醇类多酚的积累。
[Objective] To elaborate the effect of soil drought on the temporal and spatial accumulation of flavanols during grape berry development process.[Method] With Vitis vinifera berry as material,the soil drought was simulated during grape berry development by controlling irrigation through the prevent-rain and root-cutting groove.[Result] The spatial accumulation pattern of flavanols in grape berry was not changed,and the highest content of flavanols was founded in stem,followed by seed and peel,flesh was the lowest.Meanwhile,during the development process of grape,soil drought significantly promoted the accumulation of flavanols in the flesh and seed.[Conclusion] Soil drought could not change the temporal and spatial accumulation law of flavanols during grape berry development,but promote the accumulation of flavanols in fresh and seed.
