DNA polymorphism difference between root system and rhizosphere soil arbuscular mycorrhizal fungi of Prunus mume by AFLP analysis [PDF]
, 2015 应用巢式PCr并进行梅根系与根围土壤丛枝菌根真菌(ArbuSCulAr MyCOrrIHIzAl fungI,AMf)dnA扩增片段长度多态性(AMPlIfIEd frAgMEnT lEngTH POlyMOrPHISM,AflP)的差异比较,研究梅共生AMf的作用机理。结果表明,从18个梅品种的30个根围土壤样品中有28个样品获得纯化的dnA片段,占样品数93.3%,样品平均多态性位点数为6.5个,nEI’S基因多样性为0.3559±0.1382,SHAnnOn信息指数为0.5299±0.1676 ...

Shuitu Baochi Xuebao, 2005 土壤微生物量碳、基础呼吸作用、土壤代谢商是表征土壤质量的重要指标,并且与土壤本身的理化性质有关。脱氢酶活性是土壤微生物种群及其活性的重要敏感性指标之一。通过室内培养,研究了不同铅添加水平(200~1 200 mg/kg)对青紫泥田微生物生物量碳及土壤基础呼吸作用、土壤代谢商、土壤脱氢酶的影响。研究表明:随培养时间延长,青紫泥田生物量碳呈下降趋势,基础呼吸作用随铅浓度升高而加强。土壤代谢商随培养时间延长变化趋势不同。外源铅胁迫下土壤脱氢酶活性随铅处理浓度升高明显受抑制。相关分析表明 ...
