油茶籽脂肪酸成分含量与高光谱反射率的相关性

Correlation between camellia seed aliphatic acid composition and hyperspectral reflectance

测定来自不同产地的30个油茶籽样品的油酸、亚油酸、棕榈酸含量和高光谱反射率，分析油茶籽高光谱反射率与脂肪酸含量间的相关关系。结果显示，与油茶籽脂肪酸成分含量相关性比较好的高光谱波段主要分布在400～500、600～630nm以及900am左右，且敏感波段区高光谱反射率与脂肪酸成分含量的相关系数均在0．4以上。

By testing the mount of oleic acid, linoleic acid, and palmitic acid of 30 samples of camellia seeds and their hyperspectral reflectance, this paper analyzed correlation between camellia aliphatic acid amount and their hyperspectral reflectance by means of quantitative analysis. The result showed that the hyperspectral bands that had a close connection with the correlation of aliphatic acid of camellia seed were particularly located in the 400-500 nm, 600-630 nm, and 900 nm. In addition,in the sensitive hyperspectral bands, all the correlation coefficients between the hyperspectral reflectance and the aliphatic acid amount were more than 0.4.
