摘　　要：以分别嫁接于枳和枳橙两种砧木的纽荷尔脐橙、福本脐橙和斯宾诺索红橘三个品种的柑橘果实为试材,采用傅里叶变换红外光谱(FTIR)和主成分分析(PCA)的方法研究了砧木对不同品种柑橘果皮和果肉物质组成的影响。结果表明:在不同品种间以及在同一品种不同砧木间果皮和果肉的红外光谱在峰形、峰位和吸收强度上均存在差异;果皮和果肉二阶导光谱的主成分分析得分图可明显区分开不同砧木的纽荷尔脐橙和不同砧木的福本脐橙;造成差异的物质的特征峰在主成分分析载荷图上的绝对值较高,这些物质以多糖、蛋白质,以及含有C=O、C-CH_(3)基团和C=C的物质为主;不同砧木对不同品种柑橘果皮和果肉的物质组成有不同的影响。The citrus fruits of three varieties,Newhall navel orange,Fukumoto navel orange and Spinoso red tangerine grafted on the trifoliate orange and citrage were used to study the influence of rootstocks on the composition of different citrus peels and pulps by Fourier transform infrared spectroscopy(FTIR)and principal component analysis(PCA).The results showed that the peak shape,peak position and absorption intensity of the infrared spectra of pericarp and pulp were different.The PCA of the second conductance spectra of peel and pulp could clearly distinguish Newhall navel orange,Fukumoto navel orange and Spinoso red tangerine grafted on the trifoliate orangeand citrage.The characteristic peaks of the substances that caused the difference had higher absolute values on the load chart of principal component analysis.These substances were mainly polysaccharides,proteins,substances containing C=O,substances containing C-CH_(3) group and substances containing C=C.The effects of rootstocks on peel and pulp of citrus of three varieties were different.
