染色体片段置换系(chromosome segment substitution lines, CSSLs)是利用一系列的杂交、回交、自交和分子标记辅助选择相结合的方法建立起来的覆盖植物基因组的一系列的近等基因系。利用遗传背景相对纯合的染色体片段置换系可以提高QTL定位的精确性。利用遗传背景相同的CSSL之间杂交,可以将不同片段上的多个优良基因快速聚合,培育出具有更多优良性状的新品种。水稻是世界上

本文综合国内外关于棉花地上部形态发与蕾铃脱落的生理生态研究成果,基于2010-2011年在江苏南京进行的不同低温敏感性品种分期播种试验、棉花花铃期短期渍水试验和2009-2011年在江苏大丰和东台进行的氮肥试验、密度试验与渍水试验。运用作物模型学原理和系统分析法,在统计分析基础上,综合量化棉花地上部形态指标与蕾铃脱落过程和环境因子间的动态关系。基于累积温光效应(TSE)确定了氮素和渍水对棉花地上部
The transport of runaway electrons in a high-temperature plasma is relatively easy to measure in a steady state experiment and a perturbation experiment, which
We propose a most simple and experimentally feasible scheme for teleporting unknown atomic entangled states in driven cavity quantum electrodynamics (QED). In o
