摘要

对葡萄(Vitis vinifera cv)进行了田间研究。以赤霞珠(Cabernet Sauvignon)为研究对象，研究不同的落叶时间(花前、花后和花期)和落叶严重程度对葡萄果实中3-异丁基-2-甲氧基吡嗪(IBMP)浓度和关键相关基因表达水平的影响。在采收时，所有落叶处理后葡萄体内IBMP浓度均显著降低。落叶处理越早、越重，IBMP浓度越低。在所有处理中，VvOMT3在浆果果皮中的相对表达量与IBMP积累量呈密切正相关。提前落叶加上收获时间延迟1周可能是控制葡萄中IBMP浓度的有效管理策略。

The effect of defoliation on the 3-isobutyl-2-methoxypyrazine biosynthesis in wine grapes

Field studies were conducted on Vitis vinifera cv. ‘Cabernet Sauvignon’ to evaluate the effects of the defoliation time (pre- and post-flowering and veraison) and severity on the 3-isobutyl-2-methoxypyrazine (IBMP) concentration and expression levels of the key related genes in grape berries. The IBMP concentration in the grapes decreased significantly at harvest after all the defoliation treatments. The earlier and heavier the defoliation treatment, the lower the IBMP concentration. The relative expression level of VvOMT3 in the berry skin was closely positively correlated with the IBMP accumulation in all the treatments. Early defoliation coupled with a 1-week delay in theharvest time may be an effective management strategy to control the IBMP concentration in grapes.
