查询词典 grape phylloxera

Standard blends of Madeira are made mainly from the local grape varietal Tinta Negra Mole, whereas higher quality "reserve" and "vintage" Madeiras tend to be made from one of the four noble grapes traditionally used to make Madeiras—Sercial, Verdelho, Bual, and Malmsey (listed in ascending order of sweetness). All four of these noble grapes were destroyed by phylloxera at the end of the 19th century and are slowly being replanted on the island at considerable expense.

标准马德拉白葡萄酒主要采用当地的Tinta Negra Mole葡萄酿造而成；而品质较高的"珍藏"及"年份"级马德拉葡萄酒往往会采用四种传统用于酿造马德拉葡萄酒的贵族葡萄之一：Sercial葡萄、Verdelho葡萄、Bual葡萄或 Malmsey葡萄。19世纪末，岛上的四种贵族葡萄都遭受了根瘤蚜虫的彻底破坏，后来付出不小代价后，才重新在岛上种植。

This is common practice because North American grape species are resistant to phylloxera, a root louse that eventually kills the vine.

In this study, laboratory bioassays were carried out for rapid initial evaluation on the resistance of 10 grape rootstocks and 18 cultivars to Chinese biotypes of grape phylloxera, Daktulosphaira viticola. The survival ratio, developmental duration, egg number and index for population age constitution were evaluated.

为了检测我国葡萄品种和砧木对中国生态型葡萄根瘤蚜Daktulosphaira viticola的抗性，在实验室条件下采用离体根接种法鉴定了10个葡萄砧木、18个葡萄栽培品种，测定了根瘤蚜存活率、发育历期、产卵量、种群龄期结构指数和成虫大小等指标。

To probe into either the attractiveness to or avoidance from phylloxera of grape rootstocks and cultivars with different tolerance, as well as into the volatile components from their roots, the method of invitro root segment culture was used to investigate the selectivity of Phylloxera viticola Fitch to the roots of grape rootstocks '5BB' and '140Ru' and cultivar 'Kyoho'.

为了探讨不同抗性水平砧木及品种对根瘤蚜吸引及驱避效应以及鉴定挥发性物质组分，采用离体根段培养法测定葡萄根瘤蚜Phylloxera viticola Fitch对砧木5BB，140 Ru及栽培品种巨峰的选择性，发现根瘤蚜对栽培品种巨峰的根段具有很强的选择性，至接种后3d，67.13%的根瘤蚜优先选择巨峰；而对5BB和140 Ru的选择性却很差，分别有15.29%和17.58%的根瘤蚜选择5BB及140 Ru。

Three days after inoculation, 67.13% grape phylloxera selected 'Kyoho', while only 15.29% and 17.58% phylloxera selected '5BB' and '140Ru', respectively.

对砧木5BB和巨峰根系的挥发性组分进行测定，发现2个品种挥发物独有组分数量均较高，巨峰独有组分为23个，占总成分数的48.94%，5BB的独有组分为32个，占总成分数的57.14%。5BB和巨峰的共有组分为24个，主要成分均为亚油酸甲酯和反油酸甲酯，但含量有所不同，其中，5BB以倍半萜类的丁香醇及脂肪酸甲酯类的亚油酸甲酯，反油酸甲酯，棕榈油酸甲酯含量较高，高于巨峰中相应物质含量的4.23%~6.46%，而巨峰以邻苯二甲酸二丁酯及胆甾烷含量较高，分别高于5BB相应组分含量的6.81%和1.07%。

The resistance of 20 Vitis vinifera varieties, 18 V. vinifera- V. labrusca varieties, 11 hybrides producteurs direct, 6 grape rootstocks, 3 wild grapes and 1 hybrid of wild grape and V. vinifera to grape phylloxera (Daktulosphaira vitifoliae Fitch ) were evaluated. The survival ratio, number of eggs,phylloxera and the tuberosity were evaluated.

采用离体根接种法对葡萄20个欧亚种、18个欧美杂种、11个种间杂种直接生产者HPD、6种砧木、3个野生种和1个野生种与欧亚种的杂交后代接种葡萄根瘤蚜 Daktulosphaira vitifoliae ，测定根瘤蚜生长发育相关指标及根瘤比例。

The grape is the fruit preferences, but serious grape phylloxera, has been identified as the main quarantine objects at home and abroad.
