摘要
2009年7—8月对蓬莱地区酿酒葡萄果实病害种类和发病情况进行了系统的观测和调查,结果发现:引起该地区葡萄中后期烂果的主要病害有炭疽病、灰霉病、白腐病和酸腐病,其中,炭疽病和白腐病发病较重,其次是灰霉病,酸腐病相对发病轻,且随着葡萄果实的日渐成熟,病害发病逐渐严重。室内抗病性测定发现,无伤葡萄果实对炭疽病、曲霉病和灰霉病具有不同程度的抗侵入特性,对3种病害有伤接种后的病情指数进行Duncan新复极差法差异显著性分析,赤霞珠对3种病害表现出较强的抗性,其次是蛇龙珠。
A survey of wine grape fruit-rotting disease was conducted during the 2009 growing season in Penglai. It found Colletotrichum gleosporioides, Coniothyrium diplodiella, Botrytis cinerea and sour rot were responsible for much of bunch rot in vineyards in late August. The two former diseases were the most prevalent fruit disease at that times, Botrytis cinerea was on the second, Sour rot was a lesser rot degree than others. In the inoculation tests in laboratory, it showed that the unwounded grape fruits had lower infection rate than that of the wounded fruit and resistance to the infection of three tested pathogen （Cgleosporioides, Cdiplodiella and Aspergillus sp.）. In addition, five grape varieties differ in the incidence and disease indexes of fruit rot. Cabernet Sauvignon had the strongest resistance in the five tested varieties. Carbemet Gemischet took secondplace.
