Root Analysis System

Purpose:

HM-GX02 root analysis system is a set of professional root washing, and can also be used for root box culture plant root phenotype analysis, can analyze root length, diameter, area, volume, root tip count, etc., powerful functions, simple operation, the software can analyze the morphological analysis of plant roots and the overall structural distribution of the root system, etc., widely used in root morphology and structure research.

Principle:

HM-GX02 root analysis system uses a high-quality graphic scanner to obtain high-resolution plant root color or black and white images. The scanner is equipped with a special dual-light source lighting system under the scanning panel and in the upper cover, and a dual-light source calibration area is reserved on the scanning panel. In addition, it is also equipped with special, high-transparency root placement trays of different sizes. During scanning, the light source under the scanning panel and the light source in the upper cover simultaneously scan the root samples in the high-transparency root plate, which can avoid the shadows and unevenness that are easy to occur during root scanning, and effectively ensure the quality of the acquired image.

This soft root analysis software can read images in TIFF and JPEG standard formats. For the acquired images, the high-quality root images obtained by scanning are analyzed using the software decrypted by inserting the dongle. The basic morphological parameters such as the length, diameter, area, volume, and root tip of the cross-overlapping part of the root system are measured and calculated using non-statistical methods. This meets the researchers’ research on different categories and levels of plant roots.

(13) User-defined segmented diameters at unequal intervals, automatically measuring the length, projected area, surface area, volume, etc. of each diameter segment, and its distribution parameters.

(14) Root color analysis can be performed to determine the number of surviving roots, and output the diameter, length, projected area, surface area, and volume of roots of different colors.

(15) It can perform topological analysis of the root system, automatically determine the number of root connections, relationship angles, etc., and can also automatically analyze the length, area, volume, etc. of the main root or any lateral root separately. It can display the corresponding parameters of any diameter segment of the marked root system separately (customizable at unequal intervals).

(16) It can automatically measure the fractal dimension of the root system using the box dimension method. It can analyze the proportion of rhizobium volume in the root system to objectively determine the contribution of rhizobium body.

(17) It can perform large-scale fully automatic root system analysis, and can edit and correct each analysis result graph.

(18) It can perform large-scale automated estimation of root biomass distribution.

(19) It can analyze the characteristics of the angle of azimuth, horizontal angle analysis, and main root extraction analysis.

(20) Each analysis image, distribution map, and result data can be saved and exported to an Excel table, and the analysis mark map can be exported.

(21) The instrument has cloud platform support, and the analysis data can be saved to the cloud for viewing anytime and anywhere.
