A development of near infrared imaging spectroscopy with heavy water to visualise water movement in plants

由于氧化氘（D_2O）的化学特性与水相似，因此，植物对它的吸收量很大，可以作为研究植物水分关系的良好示踪剂。在特定的近红外波段，近红外不是被D2O吸收，而是被水吸收。因此，近红外成像和D2O示踪剂的组合提供了一种观察植物水分运动的方法。在这项研究中，我们建立了宏观和微观可视化方法来研究植物水分运动。我们还开发了这种新方法的用户界面。

Because the chemical characteristics is similar to water, deuterium oxide (D2O) well up-taken in plants can be a good tracer to study plant water relations. At a specific near infrared waveband, near-infrared is absorbed not by D2O but by water. Therefore, a combination of near-infrared imaging and D2O tracer provides a method observing water movement in plants. In this study, we established macroscopic and microscopic visualization methods to investigate water movement in plants. We also developed an user interface for this novel method.
