查询词典 Podosphaera

Results showed that mycelial growth and conidial formation of Podosphaera xanthii were inhibited on resistant pumpkin cultivars.

因此，在筛选抗白粉病的南瓜品种时，可以把接种后POD和PPO酶活激发与否作为鉴别是否为抗病品种的依据之一。

Result3 strains of endophytic fungi had growth peak when the pH value was 6.5-7.5,and could grow within pH of 4.0-8.5. Their acid-alkali adaptability was strong,in which the P-3 adaptability was the strongest. P-1and P-2 had the stronger inhibition to the Bacillus subtilis,Escherichia coli and Staphylococcus aureus,and P-3 only had the little inhibition to Escherichia coli. The 3 endophytic fungi all had inhibitory effect on Podosphaera leucotrlcha,Alternaria mali,and Gymnosporangium yamadae Miyabe,in which,P-1 had the better inhibitory ability.

结果3株内生真菌在pH值6.5～7.5出现生长最高峰，在pH值4.0～8.5都可以生长，酸碱适应性很强，其中P-3的适应性最强。P-1和P-2对枯草芽孢杆菌、大肠杆菌、金黄色葡萄球菌都有较强的抑制能力，而P-3只对大肠杆菌有很微弱的抑制能力。3株内生真菌对苹果锈病病原菌、苹果白粉病病原菌、苹果落叶病病原菌都有抑制作用，其中P-1的抑制能力较强。

Based on using those specific PCR primers, a unique 190 bp hand was obtained by PCR amplification from genomic DNA of Venturia inaequalis of apple and it can be accurately distinguished from patbogens of Alteraria mali, Marssonia mali and Podosphaera leucotricha, the common apple leaf spot diseases.

利用这对引物能从苹果黑星病菌基因组DNA中扩增出一条分子量为190bp的特异性条带，准确地把苹果斑点落叶病、苹果褐斑病和苹果白粉病等常发性苹果叶斑病害区分开。

To accelerate the speed of identification and find a new sereening method, various pumpkin cultivars with different resistant levels to Podosphaera xanthii were studied on the histopaibology by staining assays in this investigation.

为了寻找简便有效的品种鉴定方法，采用透明染色法比较了不同抗性南瓜品种接种白粉病菌后的组织病理表现，并用电泳分离法分析了这些品种染病前后过氧化物酶、多酚氧化酶和超氧化物歧化酶的同工酶谱变化。

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。
