用AFLP分子标记技术对 5 0个有代表性的玉米及其野生近缘种大刍草、摩擦禾、薏苡材料进行了遗传关系分析。利用 2 1个PstⅠ MseⅠ引物组合检出可辨认带共 6 4 1条,其中多态性带 5 86条,平均每对引物得到 30 5 2条多态性带,多态性 91 4 %。聚类分析结果表明,可以将 5 0个材料分为 3大类,与已有的玉米族分类一致,但与玉蜀黍属内的种间和种内分类存在差异,说明大刍草各种内存在较大的遗传多样性。本实验发现玉蜀黍属与摩擦禾关系比与薏苡的关系更近,但并没有发现玉米与小颖玉米亚种比与其他大刍草的遗传关系更近。

A two-component carbon tetrachloride system and a two-component aqueous system have been treated with the proposed strategy where only 21 calibration samples are needed, and the result showed that the predictive ability was not obviously impaired for the former system while being clearly strengthened for the latter one in comparison with a conventional way that required a calibration set of 100 samples.5 An unlooked-for experimental observation that in near-infrared spectroscopy the second overtone of aniline adsorbed by 13X molecular sieve nearly disappeared led us investigate a fundamental problem: the behavior of NIR when the outside space surrounding a molecule is too small to allow the molecule to vibrate freely.
同时,最小相关样本设计能进一步减少所需的校正样本数,且能提供更多合适变量以建立多元校正模型。这两方面的改进使模型的预测能力得以提高,其预测精度即使在水体系中也有明显的改善。五、近红外漫反射光谱在线非接触监测气-固吸附过程中出现了一个意外现象,即在近红外光谱上,被13X分子筛吸附的苯胺的二级倍频几乎完全消失了。这促使笔者深入探讨了近红外光谱的空间效应(当一分子被一足够小的刚性空间限制时,其振动的受限导致一级倍频和二级倍频强度均减少,并且后者减少的程度比前者更大)。
