(A) 健康茶梢(ITS)、叶蝉为害茶梢(TSITGL)和茶树花(TF)挥发物在前2个隐变量(LV1与LV2)的得分图(椭圆为基于Hotelling T2计算出的95%置信区间); (B) 偏最小二乘法判别分析双标图(实线圆半径为1.0); (C) 各挥发物(编号同表4)的变量重要性投影图(VIP), 上图为挥发物VIP≥1, 下图为挥发物VIP<1。

Figure 5. The partial least square discriminant analysis (PLS-DA) for volatiles
(A) Scores with respect to the LV1 and LV2 (the eclipse denotes the 95% confidence interval based on Hotelling T2) for volatiles from intact tea shoots (ITS), leafhopper-infested tea shoots (TSITGL) and tea flowers (TF); (B) The biplot in PLS-DA (the dashed line is a guideline for 1.0); (C) The variable importance for the projection (VIP) for volatiles (the number is the same as Table 4). Volatiles with VIP≥1 are shown on top, and volatiles with VIP<1 are displayed at bottom panel.
