黄萎病

This paper reviewed microsclerotia or spores in soil are stimulated to germinate by host root exudates, hyphae colonizes on the surface of root, pathogens penetrate epidermis and develop in cortex, expand on stem and leaf, and symptom development, shows that host plant develops various barriers to restrain this fungus invasion.

本文系统探讨了土壤中微菌核或孢子受寄主根系分泌物的刺激，开始萌发、产生的菌丝在寄主根表面定殖、穿过表皮、在皮层中发生及在寄主体内扩展和症状形成等黄萎病菌侵染棉花的过程，阐述了寄主植物形成多级防御反应阻击病原菌的入侵。

In greenhouse the pathotype of 41 strains of Vertwilltum dahliae of cotton were studied by maculating the seedlings of 4 different cotton cultivars, EjingNo. 1~ Zhong-12 WcnS and TangmianNo.2. 41 stains were clustered into 2 groups: defoliating types and nondefoliating types.

采用8个棉花黄萎病菌代表菌系和33个北方菌系，在温室条件下，选用鄂荆1号、中-12、文5和唐棉2号4个不同的棉花品种进行致病性测定，其结果根据病株落叶与否可将供试菌系分为落叶型与非落叶型两类。

Some of your guests may dry or press the fresh flowers to create a memento but the majority of them will simply discard the flower once it wilts .

您的一些客人，可干，或者按鲜花，以创造一个纪念品，但他们大部分将简单抛弃花卉一旦黄萎病。

Fifty-two China-bred and introduced cottons with Fusarium and Verticillium wilts resistance were used to study their pedigrees and the effects of pedigree proportion on yield components. The results indicated that Deltapine and Stoneville descents contributed to the most of the varieties in proportion, followed by Foster.

对我国引进和育成的52个抗枯、黄萎病品种的系谱及其对产量性状的影响进行分析，结果表明岱字棉与斯字棉血统在52个品种中占有较大的比例，其次是福字棉，而其他品种的血统较少。

Genetic diversity of 105 Chinese key cottons with Fusarium and Verticillium wilts resistance was studied based on AFLP markers. Twenty primer combinations were selected to perform the AFLP fingerprinting from 100 primer combinations.

利用AFLP分子标记技术，对我国20世纪50年代开展抗枯、黄萎病育种以来培育的105份骨干品种的遗传多样性进行了研究。

Specific for anti-hail, strong winds, Drought, salinity, high temperature, anti-bird damage, anti-rust, charcoal rot, resistant to Sclerotinia sclerotiorum, Verticillium wilt resistance, lean Thin.

具体为抗冰雹、强风、干旱、盐碱、高温，抗鸟害，抗锈病、炭腐病，耐菌核病、黄萎病，耐瘠薄。

Although much progress has been made in prevention and control of Vertidllium wilt of cotton, the progess is slow.

国内外在棉花黄萎病防治及抗病育种方面虽然取得了一些进展，但进展缓慢。

In this research, two genes were used to develop broad-spectrum disease resistance cotton. On one hand, new data could be added for resolving the"century puzzle"—cotton Verticillium wilt, on the other hand, new experiences could be acquired for disease resistance gene englneering of other crops.

本论文提出了利用这两个基因来培育抗黄萎病棉花的设想，一方面为解决这个&世纪性&难题积累新的资料，另一方面也为其它作物的抗病基因工程提供新的经验。

The strain and its fermentation can inhibit many pathogenic fungi and control the related important plant disease such as Verticillium wilt of cotton, cumber powdery mildew, and so on.

前期研究表明，该菌株及其发酵液对棉花黄萎病菌等多种重要的植物病原真菌具有较强的抑制作用。

The mechanism of Verticillium wilt resistance in cotton is very complex which include both the instinctive resistance in cotton plants and the induced resistance by Verticillium dahliae infecting.

棉花黄萎病抗病机制是很复杂的，既有棉株体固有的抗性，又存在病菌侵染诱发的抗性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
