Sampling Survey and Identification of Races of Soybean Cyst Nematode （Heterodera glycines Ichinohe） in Huang-Huai Valleys 总被引：2，自引：0，他引：2
LU Wei-guo GAI Jun-yi LI Wei-dong 《中国农业科学(英文版)》2006,5(8):615-621
Soybean cyst nematode （SCN Heterodera glycines Ichinohe） is one of the most important nationwide soybean diseases in China. A total of 38 soil specimens or locations in the area was sampled and tested for SCN races during 2001-2003 for the inspection of race distribution in Huang-Huai Valleys. A map of race distribution was constructed according to the data from both the present study and the published reports cited. Three areas, namely, the area of southeast to Jinan in Shangdong Province; the area of northern Henan Province and its border region to south of Hebei Province; and the area of Luohe, Zhoukou of Henan Province and Fuyang of Anhui Province mainly infested with Race 1 were identified. Race 4 was predominant in Shanxi Province, Beijing and the adjacent area of Henan, Shandong, and Anhui provinces, and the delta of Huanghe River in Shandong Province. Race 2 was mainly found in Liaocheng, Dezhou of Shangdong Province and Shijiazhuang of Hebei Province, and Jiaozuo and Huojia of Henan Province. Race 7 was distributed in the west part of Jiaodong Peninsula of Shandong Province and Kaifeng, Huaxian, Wenxian of Henan Province. Race 5 was found and scattered in Hebei and Henan Province. Race 9 was found in Shangqiu of Henan Province, which was reported for the first time in China. It can be seen that Race 1 and Race 4 were the two predominant races in Huang-Huai Valleys, and that research should focus on developing resistant cultivars of these races. There might exist other races in an area with some predominant races. The race substitution in the past decade was not obviously found, therefore, the results should be meaningful to future breeding for resistance to SCN in Huang-Huai Valleys. 相似文献

黄淮地区大豆胞囊线虫生理小种的抽样调查与研究 总被引：4，自引：1，他引：4
【目的】探讨黄淮地区大豆胞囊线虫（Heterodera glycines Ichinohe）的种类及其分布。【方法】2001～2003年在黄淮大豆产区依据Riggs的鉴别模式对38个地点大豆胞囊线虫（SCN）生理小种作抽样调查，并结合文献资料，绘制出黄淮地区大豆胞囊线虫生理小种分布图。【结果】大豆胞囊线虫主要分布在山东、河北、北京、山西大部分地区、河南东部与北部、安徽北部；在山西南部及河南西南部地区的抽样调查中未检测到大豆胞囊线虫。其中1号生理小种主要分布在山东济南以南及以东地区，河南北部与河北南部交界地区，河南漯河、周口及安徽阜阳地区。4号生理小种主要分布在河南、山东、安徽交界地区，山西、北京地区，以及山东黄河三角洲地区。2号生理小种主要分布在山东聊城、德州地区，河北石家庄地区，河南焦作、获嘉地区。7号生理小种主要分布在山东半岛和河南开封、滑县、温县等地。5号生理小种在河南和河北有零星分布。另外，在河南商丘地区新发现有9号生理小种。【结论】黄淮地区的优势小种是1号和4号生理小种，抗线虫育种应该以兼抗1号和4号生理小种为主要目标。各生理小种的分布没有明显分界，优势小种分布区域中存在其他生理小种。在过去的10年中，该地区生理小种的组成相对稳定，本研究结果可供大豆抗线虫育种参考。 相似文献

燃煤烟气对土壤-小麦系统中汞累积及分布的影响 总被引：1，自引：0，他引：1
为研究燃煤烟气对土壤-小麦系统中汞积累和分布的影响,在小麦苗期和成熟期采集河南省商丘市某燃煤电厂周围农田土壤和小麦植株样品,用ZYG-Ⅱ型智能冷原子荧光测汞仪测量样品中的汞含量。结果表明,小麦苗期和成熟期,土壤样品中汞含量没有超过土壤环境质量标准(GB15618—1995)二级标准的限值。燃煤电厂周围表层土中汞含量要明显高于深层土,呈表层富集现象,苗期小麦根的汞含量高于茎叶,其根、茎叶的汞含量与表层土的汞含量呈显著正相关。小麦从苗期到收获期,表层土、小麦根和茎叶的汞浓度升高。小麦从苗期到收获期,茎叶面积迅速增加,小麦叶片直接从大气中吸收燃煤烟气中的汞,使小麦茎叶通过叶面吸收的汞浓度增加,收获期燃煤电厂周围小麦各器官汞含量为茎叶>根>颖壳>籽粒。成熟期小麦根的汞含量与表层土的汞含量呈显著正相关,而茎叶汞含量与表层土的汞含量无相关性。因此,燃煤烟气中汞沉降影响燃煤电厂周围种植的小麦各器官对汞的吸收和累积。 相似文献
