Chlorophyll fluorescence induction is widely applied to investigate plant growth conditions by calculating the ratio of its intensity at oxidized and reduced states. We examined the applicability of a time-resolved profile of chlorophyll fluorescence induction with the aid of multivariate analysis to monitor the leaf water stress. Principal component (PC) analysis of time-resolved images of chlorophyll fluorescence induction and their score images were reconstructed. Control leaves (non-stressed leaves) and water-stressed leaves could be classified by normalized PC3 score images. This technique has the potential to monitor the water stress condition of plants by using a simple device.
叶绿素荧光诱导广泛应用于通过计算其氧化和还原状态的强度比来研究植物生长条件。我们利用多变量分析来监测叶片水分胁迫，检验了叶绿素荧光诱导时间分辨谱的适用性。重建了叶绿素荧光诱导时间分辨图像及其得分图像的主成分（PC）分析。归一化的 PC3 得分图像可用于区分对照叶片（非胁迫叶片）和水分胁迫叶片。该技术具有通过使用简单设备监测植物水分胁迫状况的潜力。
