Abstract

The feasibility of Near Infrared Spectroscopy to detect fungicide treatment on wheat samples was assessed. A total of 213 durum wheat samples from four different trial sites in Andalusia (southern Spain), with different agroclimatic conditions (soil, temperature, rainfall) were selected for been analyzed on VIS+NIR (400 nm-2500 nm) and NIR (1100 nm-2500 nm). Different mathematical pre-treatment on the signal (scatter correction and derivatives) were evaluated for their discrimination accuracies. Using MPLS, the selected models obtained 84% of well classified samples.

摘要

评估了近红外光谱法检测小麦样品中杀菌剂处理的可行性。从西班牙南部安达卢西亚的四个不同试验点（具有不同的农业气候条件（土壤、温度、降雨））选择了总共 213 个硬质小麦样品，用于在 VIS+NIR（400nm-2500nm）和 NIR（1100nm-2500nm）上进行分析。对信号进行了不同的数学预处理（散射校正和导数），以评估其判别精度。使用 MPLS，所选模型获得了 84%的良好分类样本。
