锈菌

Wheat leaf rust, caused by Puccinia triticina, is one of the most important wheat diseases in the world. The leaf rust fungus is adapted to different climates, the disease can be found in diverse wheat growing areas throughout the world.

由小麦叶锈菌引起的小麦叶锈病是小麦生产上的主要病害之一，适宜范围广，发生区域大，严重发生时可造成5%—15%甚至更高的产量损失。

Meanwhile, The American Farm Bureau Federation has joined with the ASA and urged USDA to ban soybean imports from countries with Asian rust fungus until a government study of its risk was completed.

同时，美国农场办公署联盟也与大豆协会站到了一起，共同敦促农业部在政府完成风险研究之前禁止从出现亚洲锈菌的国家进口大豆。

Around 5% of farmers in Goias, Brazil's fourth biggest soy-producing state, went to court to break soy contracts closed before harvesting after prices increased significantly at the start of this year and Asian rust fungus decimated production in parts of the state.

在巴西第四大产豆州果尔斯，由于年初价格明显上涨且亚洲锈菌造成了部分地区产量的减损，有5％左右的农民前往法院要求撤销收割前商定的合约。

The threat of widespread infestation by the Asian soybean rust fungus is nearly over for this year's crop, according to Deputy Agriculture Secretary Chuck Conner.

美国农业部副部长查克·科纳说，本年度作物大面积感染亚洲大豆锈菌的风险已基本不存在。

The Asian rust fungus and wet weather could cut soybean production potential by 15% in Brazil's top-producing state of Mato Grosso in the current 2002-03 season (October-September), a top government pathologist said last week.

巴西政府一位最高级别的植物病理学家上周说，亚洲锈菌及潮湿天气将使巴西最大的产豆州马托格罗索在2002－2003年度（头年10月至次年9月）遭受15％的产量损失。

In this research, the activities of CWDE were measured by saccharifying according to the theory that red-brown amino compounds were produced when 3, 5-dinitro salicylic acid and aldehyde were heated together. And the testing conditions were made clear. The activity of Cx should be tested with optimal temperature of 50℃, optimal pH of 4.8, incubation time of 30 min, and optimal substrate of 0.6% CMC-Na. Due to the heat-libality, Cx should be sterilized more than 10 min. The testing conditions of the activity ofβ-G were almost the same with Cx except the substrate of 0.5% salicin and the sterilization time of more than 15 min.

主要取得了一下成果：(1)明确了条锈菌细胞壁降解酶活性测定的条件：羧甲基纤维素酶活性的测定条件为50℃，pH4.8，反应时间30min，底物浓度为0.6%羧甲基纤维素钠，以DNS法测定，且失活酶液的灭活时间应大于10min；β-葡萄糖苷酶活性的测定条件为：50℃，pH4.8，反应时间30min，底物浓度为0.5%水杨苷，以DNS法测定，且失活酶液的灭活时间应大于15min；果胶酶活性的测定条件为：50℃，pH4.8，反应时间1h，底物浓度为0.25%果胶，以DNS法测定，且失活酶液的灭活时间应大于10min。

Meanwhile, USDA reported that Asian soybean rust was found in Georiga's southwestern most county of Seminole, near the town of Donalsonville.

同时，美国农业部说，在佐冶亚洲西南部的塞米诺县发现了亚洲大豆锈菌。

Elicitors can be found in intercellular washing fluidsin highly incompatible interaction between wheat and stem rust.

小麦接种高度非亲和性的小麦秆锈菌后，在其细胞间隙液中可能存在激发子。

These powder is summer rust spores and teliospore.

这些粉状物就是锈菌的夏孢子和冬孢子。

In this experiment the surface structure of seed coats was observed and a test of the quantity of teliospore on the seed coat was done. The result indicated that the deeper and more the longitudinal grooves and villoses the seed coat are the larger the teliospore's quantity is.

试验主要对六个红花品种种皮上锈菌冬孢子的负荷量与其种皮表面结构进行了观察，查明种皮纵沟较多、较深，且表面绒毛较多的品种，冬孢子负荷量较大，反之则少。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
