枯萎的

In recent years, watermelon Fusarium wilt has become an increasing threat to watermelon production around the world.

近年来，西瓜枯萎病菌引起的西瓜枯萎病害范围逐渐扩大，危害日益突出。

In order to evaluate classification status of biocontrol B-3 and its control efficacy to pepper wilt, antifungal action of biocontrol strain B-3 to Fusarium oxysporum f.sp. vasinfectum was determined using cylinder plate method, its control efficacy to pepper wilt was study by pot and field tests, and its identification was launched by means of phenotypic characteristics observation, physiological and biochemical indexes determination and the assay of 16S rDNA sequences.

为了明确生防菌株B-3对辣椒枯萎病的防效及其分类地位，采用管碟法测定了生防菌株B-3对辣椒枯萎病菌的抑制作用，考察了其对辣椒枯萎病的防效，并采用表型特征培养观察法，生理生化测定法和16S rDNA序列分析法对菌株B-3进行了鉴定。

It was done once by Wilt, and I'm not Wilt.

这是一劳永逸的枯萎，而我不枯萎。

The results showed that T04-004 strain could significantly inhibit growth of F. oxysporum f.sp.benineasae , and the fungistatic rate was over 90%.

并与节瓜枯萎病原菌进行对峙培养，筛选出拮抗节瓜枯萎病菌镰刀菌的优良木霉菌T04-004菌株，该菌株对节瓜枯萎病菌的抑制率达90%以上。

The hypha growth-inhibiting method and the virulence determination method were used to investigate the inhibition effects of the petroleum ether fraction, chloroform fraction, ethyl acetate fraction, n-butanol fraction and water fraction in the alcoholic extracts from the aboveground of Peganum harmala L.

采用抑制菌丝生长法和毒力测定法，研究了骆驼蓬地上部醇提物的石油醚、氯仿、乙酸乙酯、正丁醇和水5个极性部位对南瓜枯萎病菌、西瓜枯萎病菌Fusarium oxysporum f。

Result The results showed that processing ⑤could not provide the necessary water to grow of seedlings, all seedlings withered and died. The seedlings growth was normal with processing ①、②. A large number leaves of processing ③ seedlings became yellow and wilt, under processing ④, lots of leaves shedded and its survival rate was 30% after 40 days water stress.

结果］结果表明，处理⑤不能提供幼苗生长所需的水分，幼苗全部干枯死亡；处理①、②幼苗生长表现正常；处理③叶片大量变黄枯萎；处理④叶片大量枯萎脱落且在控水40 d后其存活率只有30%。

Leaves die, fall, and shrivel. The heat shriveled the unwatered seedlings.

叶子凋零、飘落枯萎了；酷热使得未浇水的秧苗都枯萎了

At difierent time at ter inoculation with Fusarium oxysporum f.sp.cubenserace 4,the transcript pattems of WNB1 and WST3 was enhanced,which implied that the expression of WNB1 and WST3 may be related to the resistance of banana to Fusarium wilt.

用半定量PCR分析枯萎病菌诱导后野生蕉叶片中RGAs的表达情况，结果表明WNB1和WST3受枯萎病菌诱导后表达量增强，这表明WNB1和WST3的表达可能与香蕉枯萎病抗性相关。

The transcript of M-PAL gene in the leaves was increased when the plantlets of plantain were inoculated with Fusarium oxysporun f. sp.cubense, indicating that the expression of M-PAL may be related to resistance of banana Fusarium wilt.

对接种香蕉枯萎病菌4号生理小种Fusarium oxysporum f.sp.cubense(FOCrace4后大蕉叶片中M-PAL基因的转录谱进行研究表明，在接种枯萎病菌后，M-PAL基因在叶片中的转录水平提高，因此推测M-PAL基因的表达可能与香蕉枯萎病抗性相关。

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。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
