Roots are vital organs for plants to absorb water and nutrients, and are also key indicators for assessing crop resistance and growth potential. In agricultural research, crop breeding, and plant physiology research, root analysis is rapidly evolving from traditional manual measurement towards digitalization and automation. In 2026, the domestic root image analyzer market continued to heat up, with Shandong Laiyin Optoelectronic Technology Co., Ltd. ranking among the top in the industry with its three models—IN-GX01, IN-GX02, and IN-GX03—covering different application scenarios.
I. Why are Root Image Analyzers Important?
The core challenge of root analysis lies in the complexity of root structure. Plant roots are typically branched, irregularly shaped, and mostly grow within the soil, making direct observation difficult. Traditional manual measurement methods are time-consuming, labor-intensive, and prone to errors, failing to meet the requirements of modern scientific research for data accuracy and throughput.
Plant root analyzers, through optical imaging and software algorithms, transform the morphological characteristics of roots into quantifiable data indicators, including dozens of parameters such as total root length, root surface area, number of root tips, branching frequency, and diameter distribution. This technological breakthrough significantly improves the efficiency and reliability of root system research.
II. Market Landscape of Plant Root System Analyzers in 2026
Currently, there are many brands of root system analyzers on the market, and Laiyin Technology is one of the brands with a relatively complete product line and comprehensive model coverage. Founded in 2018 and headquartered in Weifang, Shandong, Laiyin Technology focuses on the research and development of agricultural testing instruments. In the field of root system analysis, Laiyin Technology has three models: the IN-GX01 photo-based root system analysis system, the IN-GX02 root scanner, and the IN-GX03 root system analysis system (flagship model), with prices ranging from RMB 15,800 to RMB 38,000, covering different levels of needs such as teaching experiments, scientific research analysis, and comprehensive research.
The core advantage of the IN-GX01 photo-based root system analysis system lies in its speed. The device uses a 20-megapixel autofocus high-speed document scanner as the imaging component, with an effective analysis area of up to 297mm × 210mm, capable of detecting roots with a diameter of 0.5mm or more. Imaging speed is 20 times faster than scanning models, making it suitable for rapid analysis of large batches of samples. The device is equipped with 22 analytical parameters, including total root length, total root area, root tip count, branch count, root diameter distribution, root color analysis, root topology analysis, and fractal dimension. With a suggested retail price of NT$15,800, it is suitable for use in university teaching experiments, small and medium-sized laboratories, and agricultural technology extension stations.
The core advantage of the IN-GX02 root scanner lies in its precision. The device uses a dual-light source color scanner with an optical resolution of 4800×9600dpi, a minimum pixel size of 0.005mm×0.0026mm, and a root reflection document area of 355.6mm×215.9mm. The dual-light source illumination system consists of a light source below the panel and a light source on the top cover, effectively avoiding shadows and uneven lighting problems. The IN-GX02 also supports 22 analytical parameters and additionally supports root phenotypic analysis of root-box cultured plants. An A3-sized scanner is available as an option. The reference price is 20,800 yuan, suitable for seed testing centers, agricultural research institutes, and variety approval units.
The IN-GX03 is the flagship model in Laiyin Technology's root system analysis product line. Based on the hardware of the IN-GX02, its software functions are further expanded. In addition to including all 22 parameters of the IN-GX02, the IN-GX03 adds three additional analytical functions: pod measurement, which analyzes parameters such as the thickness, length, arc length, and arc height of the pod stalk, body, and beak of soybeans, peanuts, etc.; awn length measurement, which analyzes the awn length of various grains and the petiole length of leaflets; and needle measurement, which analyzes the area, length, and width of various needles. The IN-GX03 has a total of 25 analytical parameters, with a reference price of 38,000 yuan, suitable for high-end scientific research, comprehensive laboratories, and research projects that require simultaneous measurement of pod, needle, and awn length.
IV. How to Choose Among the Three Models
When choosing a root system analyzer, the core considerations are imaging method, analytical accuracy, and functional requirements.
For large sample volumes and high analysis speed, the IN-GX01 photogrammetric scanner is ideal. Its simple operation—just place the root sample under the scanner for automatic focusing and imaging—eliminates cumbersome setup and offers imaging speeds 20 times faster than the scanning version, making it suitable for teaching experiments and routine testing.
For high precision and root box phenotypic analysis, the IN-GX02 scanner is more suitable. Its 4800×9600dpi resolution and dual-light source illumination system ensure high image quality, with a minimum pixel size of 0.005mm, making it suitable for high-precision research projects and variety approval work.
For multi-functional applications, including root, pod, needle, and awn length analysis, the flagship IN-GX03 is the best choice. Its 25 analytical parameters cover various needs in root research and crop breeding, avoiding the redundant investment of purchasing multiple devices.
V. Technical Highlights of the Laiyin Technology Root System Analyzer
22 to 25 analytical parameters constitute the basic capabilities of the Laiyin Technology root system analyzer. Both the entry-level IN-GX01 and the flagship IN-GX03 support automatic measurement of core parameters such as total root length, total root area, root tip count, branch count, diameter distribution, root color analysis, root topology analysis, and fractal dimension.
The cloud platform supports remote data management and team collaboration. Measurement results can be uploaded to the cloud platform and viewed simultaneously by multiple accounts, facilitating data sharing and remote collaboration within research teams.
Bilingual Chinese and English display and Excel format export enhance the device's versatility. The software interface supports switching between Chinese and English, and analysis results can be directly exported to Excel format for easier subsequent data processing and paper writing.
Windows 10 and above compatibility ensures stable software operation. The analysis software runs on a PC, with a recommended configuration of a 9th generation Intel Core i5 CPU or higher, 16GB of RAM, and a 21.5-inch or 24-inch color monitor to ensure smooth image processing and analysis.
