应用核基因组SSR和叶绿体基因组SSR，分析了枳属28份枳及枳杂种种质的遗传多样性及其与近缘属植物的亲缘关系。核基因组SSR分析表明普通枳的遗传差异明显，22个SSR位点的平均多态性信息含量（PIC）为0.51，平均期望杂合度为0.52，表明中国枳种质资源具有较丰富的遗传多样性。在遗传距离约0.16时，22份普通枳可以分成4个类型。叶绿体基因组SSR分析则发现普通枳间基本无差异，表明以母系遗传为特...

施氮量对不同品质类型小麦子粒蛋白质组分含量及加工品质的影响
小麦 施氮量 蛋白质组分 加工品质
2012/3/27
选用强筋小麦济麦20、中筋小麦泰山23和弱筋小麦宁麦9号，利用反相高效液湘色谱（RP-HPLC）方法测定了施氮量对不同品质类型小麦子粒蛋白质组分含量和高分子量谷蛋白亚基（HMW-GS）、低分子量谷蛋白亚基（LMW-GS）含量的影响，并分析其与子粒加工品质的关系。结果表明，随施氮量增加，强筋小麦济麦20和中筋小麦泰山23的子粒蛋白质含量及各组分含量均呈先增加后降低的趋势，施氮量为N 240 kg/h...
