枯萎

The leave fire rate was very clear in Kentucky bluegrass and Red fescue species. The chlorophyll content of Zoysia and Alkali grass changed a little.

草坪草表观质量变化突出，草地早熟禾、紫羊茅等草种的枝叶枯萎程度相当大，部分品种达到了90％以上的高叶枯萎率。

Vascular wilt caused by Fusarium oxysporum Schlecht has been a serious disease in South China, especially banana vascular wilt is fatal disease to banana industry.

华南地区因尖镰孢菌引起的枯萎病发生较为严重，特别是近年来发现的香蕉枯萎病，对香蕉产业来说更是毁灭性的病害。

The research aimed to seek the difference on rDNA-ITS sequence between Focr 1 and Focr 4 biological races of banana fusarium wilt and provide basis for rapid detection of banana difference wilt race.

寻找香蕉枯萎镰刀菌1号生理小种和4号生理小种(Focr 4)在rDNA-ITS区段序列上的差异，为香蕉枯萎镰刀菌小种的快速检测提供依据。

The strain BEB2 of endophytic Bacillus isolated from banana was identified as Bacillus subtilis according to its homology analysis of 16S rDNA sequence. The temperature, pH and medium had a significant impact to the inhibition of BEB2 to the banana wilt disease.

利用聚合酶链式反应方法对细菌BEB2做进一步的分子鉴定，并研究不同温度、pH值和培养基下BEB2发酵液对香蕉枯萎病菌生长的抑制能力，以及应用BEB2对香蕉枯萎病进行防治测试。

Through the field test and indoor research for about 3 years, it was found that the occurrence of cotton Fusarium wilt had close relationship with the climate condition in Xinjiang. when temperature was about 20℃, disease index developed very quickly. when temperature was above 24℃, disease index would reduce. With temperature dropping by the end of July and at the beginning of August, disease index would raise again.

通过田间试验和室内研究发现，新疆棉花枯萎病的发生与气候有十分密切的关系，在地膜植棉的情况下，当气温达20℃左右病指上升最快，气温达24℃以上则很快进入高温隐症期；7月下旬或8月上旬随温度下降，病情又有回升，故枯萎病在新疆也有两个明显的高峰期，只不过因地膜植棉发病期明显提前而已。

The results showed that the fermentation liquid from A44 showed strong inhibitory effect on mycelium growth and on spore germination with tower germination rate against pathogenic funguses Alternarina.alternate .

结果表明A44菌株发酵液对烟草赤星病菌、黄瓜枯萎病菌、西瓜枯萎病菌等病原菌有抗菌活性及抑制孢子萌发作用，且这种作用在A44发酵液稀释了160倍后仍然存在；对峙培养试验表明A44菌对植物病原菌有很强的拮杭作用，拮抗机制主要为营养竞争作用、抗生作用等。

Thirty-one isolates of Fusarium oxysporum were achieved from the samples of watermelon roots and soils collected in Shandong, Hubei, Anhui, Jiangshu, Hunan, Henan and Hebei. Their pathogenicity was identified by means of the co-culture methos.

从我国7个西瓜产区（山东、湖北、安徽、江苏、湖南、河南及河北）的西瓜枯萎病病株和病土样中分离获得31株西瓜枯萎病菌株，采用幼苗共培养法测定各菌株的致病力。

In addition the effect of inoculated Glomus.etunicatum was better than inoculated Glomus.clarum, which indicated that the influence of AM fungi on wilt disease was different.

同时，与接种Glomus.clarum相比，接种Glomus.etunicatum对枯萎病有较好的防治效果，说明不同菌根真菌对黄瓜枯萎病的防治效果存在差异。

With the extend of planting areas ,cucumber wilt become a severe disease all over the world to affect badly output and quality of cucumber. The output reduction in cucumber gives amount to 35%～50% every year because of the occurrence of the disease.

随着栽培面积的不断扩大，尤其是保护地温室和塑料大棚等黄瓜的大面积发展，土壤含菌量逐年累积，致使黄瓜枯萎病的发生日趋严重，每年因为枯萎病的发生造成的黄瓜减产率高达35%～50%。

The crude extracts of Sophora flavescens Ait were bioassayed by using growth-rate and pendant-drop methods for their fungicidal potential against six plant fungal pathogens at different concentrations.

采用生长速率法和悬滴法室内测试了不同浓度苦参提取物对葱菌核菌、番茄早疫菌、菜豆根腐菌、辣椒枯萎菌、黄瓜枯萎菌、茄子黄萎菌等6种蔬菜病原菌的抑菌活性。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
