黄化大麦叶的红外光谱分析

报道了南黄大麦叶的红外光谱分析，发现黄化与绿色大麦叶的生物大分子中的OH，CH2，C=O，C-O-C等基因的红外吸收峰的强度相近，而CH3基的吸收峰强度随大麦的发育呈规律性的变化，即在生长初期增强，在抽穗（4月初）后则急剧下降，联系黄化大麦叶在4月前为浅黄色，4月后逐渐转为淡绿色的叶色变化过程，认为南黄大麦叶前期黄化的原因，可能是色素中类胡萝卜素在发育初期含量较多，在转绿的4月后，其相对含量也急剧降低造成的。

THE INFRARED SPECTRAL ANALYSIS OF THE LEAVES OF NANCHONG YELLOWISH BARLEY

The IR spectral analysis of the leaves of Nanchong yellowish barley is reported in this paper, we have found out that the IR peak absorbances of the groups of OH,CH_2,C=O and C-O-C in the biomolecules of Nanchong yellowish barley are almost the same as that of the ordinary barley. But the peak absorbance of CH_3 group in leaves of yellowish barley is quite differennt from that of the ordinary barley. It regularly changes as the barley grows.
