葡萄抗霜霉病机制研究进展

Recent advances in the resistance mechanism of grape to downy mildew

葡萄霜霉病是危害葡萄的重要病害之一,该病害发生时会给葡萄生产造成严重的经济损失。本文综合分析了国内外对葡萄抗霜霉病机制研究的结果,认为葡萄对霜霉病抗性受多种因素影响,主要表现为生理生化物质、叶片形态结构及抗病遗传基因三个方面。由于各种因素对霜霉病病原菌作用关系复杂,目前对于葡萄抗霜霉病的决定性因子还没有明确结论。

Grape downy mildew is the main disease for grape,and when it was prevalent on grape,the yield of grape sharply decreased.Some grape downy mildew resistance mechanisms were analyzed.It was considered that a number of factors effecting grape downy mildew resistance,mainly including physiological and biochemical substances,leaf shape and structure and resistance gene.As a result of the complex relationships between different factors and the pathogens of downy mildew,the key factor of grape downy mildew resistance was not yet determined.
