| Abstract: | Root is an important apparatus, by which plant obtains nutrient and water from surrounding medium such as soil. Due to its special growing environment and complex morphological structure, the research of root system is more difficult than the aboveground part of plant. Observation and measurement in situ have always been the technical bottleneck for research on plant root system. In this paper, the advances of measurement technology for plant root system were summed up in brief. The attempt to get in situ plant root images was made with using MSCT imaging technology and implemented visualization of plant root growing in different medium. Further research approach was put forward after the analysis of influential factors about imaging quality. |
