摘要
用傅里叶变换红外光谱仪测定了成株期辣椒(Capsicum annuum)正常植株和根腐病植株的叶片、主根和须根3个部位的光谱。结果表明，两种植株叶片中的主要成分是蛋白质和多糖，主根和须根的主要成分是纤维素和木质素；与正常植株相比，根腐病植株叶片中蛋白质和多糖的组成发生了变化，主根中显示纤维素相对含量减少，且出现了新的蛋白质组分，须根中则显示纤维素的相对含量增加。傅里叶变换红外光谱(FTIR)可以区分根腐病对辣椒植株不同部位的影响，为辣椒根腐病的研究提供参考。
Abstract
Fourier transform infrared spectroscopy (FTIR) was used to obtain the spectra of leaf, taproot and fibrous roots of normal and root rot pepper plants in the adult stage. The results showed that for normal and root rot pepper plants, the main components of leaves were protein and polysaccharide, and for taproots and fibrous roots they were cellulose and lignin; for root rot plants, relative to normal plants, the structure of protein and polysaccharide in leaves has been changed, the relative content for cellulose of taproots has increased while fibrous roots decreased. The above results demonstrated that FTIR may be used to distinguish the effects of the toot rot on different parts of the pepper, which provided reference for the study of pepper root rot.
