Abstract

X-ray high resolution three-dimensional computed tomography (XHR3DCT) is a non-invasive technique to monitor the inner morphology of an object. It permits to obtain a series of horizontal stack of the structure that allows its 3D reconstruction of images by a computer post-processing analysis. This technology is commonly used for medical analysis on human or rarely on animals and its utilization in the plant field has been recently discussed. As we are engaged in the investigation on the possibility to use XHR3DCT for monitoring the storage quality and/or post-harvest development of fresh produces such as vegetables, here we report on minimal demonstration performed on garlic bulbs. In particular, immediately after the harvest from the soil, cloves of garlic bulbs have been maintained under different conditions differed in temperature and humidity, with and without irradiation by red (660 nm) or infra-red (735 nm) lights. At an intermediate time, some cloves have been non-invasively monitored by XHR3DCT to predict the changes in the size (volume) of growing inner shoots (sprouts). To determine the sprout volume based on the XHR3DCT-scanned images, several mathematical approaches have been tested. With approximation of the garlic sprout shape as a parabolic cone, estimation of shoot volume could be readily achieved. By analyzing the inner shoot size in garlic clove kept under different conditions, increase in the shoot size under red light or under higher temperature and relative humidity could be monitored non-invasively, suggesting that XHR3DCT can be used for monitoring of inner structure within the clove of garlic without damaging the samples. Future applications of this technique in during post-harvest managements of a wide range of fresh produces are expected.

利用x射线3d计算机断层扫描监测完整蒜瓣内蒜苗的发育
x射线高分辨率三维计算机断层扫描(XHR3DCT)是一种监测物体内部形态的非侵入性技术。它允许获得一系列的水平堆栈结构,允许其三维重建图像的计算机后处理分析。该技术通常用于人体的医学分析,很少用于动物的医学分析,最近讨论了其在植物领域的应用。由于我们正在研究使用XHR3DCT监测新鲜农产品(如蔬菜)的储存质量和/或收获后发展的可能性,我们在这里报告在大蒜鳞茎上进行的最小演示。特别是,在从土壤中收获后,蒜瓣在不同的条件下保持,不同的温度和湿度,有和没有红光(660纳米)或红外线(735纳米)的照射。在此期间,一些丁香已被XHR3DCT无创监测,以预测生长的内芽(芽)的大小(体积)的变化。为了根据xhr3dct扫描图像确定芽体积,已经测试了几种数学方法。将大蒜芽形近似为抛物线锥,可以很容易地估计出大蒜芽的体积。通过对不同保存条件下蒜瓣内芽大小的分析,可以无创地监测到红光或较高温度和相对湿度下蒜瓣内芽大小的变化,说明XHR3DCT可以在不破坏样品的情况下监测蒜瓣内部结构。预计该技术将在各种新鲜农产品的收获后管理中得到应用。
