Application areas

Application Example 1: Dynamic monitoring of root growth and development

Monitoring of dynamic growth of roots 40 days after corn emergence

usered/blueThree-dimensional glasses can watch three-dimensional effects

Application Example 2: Differences in root systems between different varieties

A relatively large angle distribution,

Relatively shorter, thicker roots

A relatively small angle distribution,

Relatively long and thinner roots

The differences in root systems between different variants of the two rice (Ra4993 and Ra5531) can be easily analyzed using the X-ray scanning imaging system of the plant root system, while the traditional method of post-root scanning will ignore the differences in angles between root systems.

usered/blueThree-dimensional glasses can watch three-dimensional effects

Application Example 3: Root System Classification

It is difficult to distinguish different plant root systems with the naked eye.With the results of the X-ray scanning imaging analysis system of plant roots, the scatter plots obtained by lateral root density and main root length as the coordinate axes can be classified.In the figure above, multiple variants are distributed in the upper part of the center line, while normal varieties are distributed in the lower part of the center line.After the two varieties are hybridized, this method can be used to quickly scan multiple characteristics of offspring.

Application Example 4: Root system response to stress

The special culture medium does not contain nutrients, moisture and any pests, so researchers can easily add different nutrients, moisture and pests to conduct stress response research.

Count measurements of nodule nematodes, the above figure is a demonstration trend of nodule changes over time

Application Example 5: X-ray imaging study of plant stems

Low-energy X-ray imaging technology can detect the ear stems of corn non-destructively. The above picture is the actual picture of the ear stems of corn ears that are obtained.

Application Example 6: Research on Seed X-ray Imaging

Non-destructive study of the internal structure of plant seeds, and compare the differences between different individuals of the same species. The above picture is a corn seed imaging picture

Application Example 7: Research on X-ray imaging of cotton wool

Viewing the three-dimensional structure of the inner sleek through three-dimensional glasses can analyze the detailed information of different parts of the inner sleek. The above picture is a three-dimensional picture of the inner sleek.
